RAy3 Microwave Link 9 Product 1. Product 1.1. Main characteristics RAy microwave units work as a point-to-point link in a full duplex setting with transfer speeds of up to 1002 Mbps. Supported are 2 license-free bands 17 GHz (17.10 17.30 GHz) and 24 GHz (24.00 24.25 GHz). Bandwidth can be configured from 3.5 up to 112 MHz, independently for Tx and Rx. Modulation can be fixed or adaptive and can be adjusted from QPSK to 4096QAM. QPSK modulation could be on the fly (without data loss) strengthened for higher receiver sensitivity by extremely robust FEC such modulation is marked as QPSK-S (S means strong). RAy microwave links operating in 17 and 24 GHz bands can also be operated as a Short Range Device (SRD). This link is formed by two RAy units, each equipped by its own parabolic antenna and accessories to be fully operational. Link transparency notes RAy links are transparent for IP and UDP Ethernet traffic (practically all protocols passes through including MPLS and many others) except following packets:
Management packets targeted for RAy units itself Special packets for protocols explicitly mentioned in this manual which are somehow processed by RAy units (like PTP) Packets which did not went through and were dis-
carded due to capacity limitation and/or policy rules
(e.g. QoS, Shaping ...). Hardware concept Fig. 1.1: RAy3 Microwave link RAy product line has been designed to have minimum possible number of hardware variants. Upgrade of functionality does not result in on-site hardware changes everything is done by activating software feature keys (see Section 1.7, Ordering codes and Chapter 5, Configuration). HW models are determined only by frequency bands, because both RAy units have identical hardware. Transmitting and receiving channels are freely defined by software and technically separated from each other by cross polarization. Note Even all units are hardware identical, default factory settings for each RAy in the pair use dif-
ferent channels for L and U unit, so the link could be established using default radio parameters. Cross polarization means that one side of the link uses one polarization for transmission (e.g. hori-
zontal) and the opposite polarization for receiving (e.g. vertical). The other side of the link is turned by 90. It therefore transmits and receives using opposite polarization with respect to the other unit. The practical result for users is that RAy units for 17 and 24 GHz must be mounted with reverse polarity on both ends of the link. 10 RAy3 Microwave Link RACOM s.r.o. Product 1.2. Mechanical interfaces This chapter describes basic properties of each RAy unit, which are important for its mechanical install-
ation: antenna waveguide, unit fixing (screws, etc.) and unit grounding (screw + cable). Other interfaces
(for data, power and service purposes) are described in next chapters Ethernet + power interfaces and Service interfaces. 1.2.1. Antenna waveguide RAy3 link requires the use of external parabolic antenna for each RAy unit both for physical mounting as well as for the wireless transmission itself. Parabolic antennas from different producers are available. Radio connection between the antenna and RAy unit is ensured by the waveguide on RAy unit (located across the holder), where well lubricated antenna waveguide pivot nicely fits in. Fig. 1.2: Waveguide pivot 1.2.2. Unit mounting The RAy unit is mechanically fixed to the antenna by 4x M8 screws (one per each side of RAy unit). Installation and basic adjustment of the antenna is described in the Section 4.2, Antenna mounting. Attaching RAy unit to it by 4x M8x30 (Allen) screws delivered with each antenna or each mount kit is described in the Section 4.3, RAy unit mounting. For adjusting the exact antenna direction see Sec-
tion 4.7.2, Directing antennas . Fig. 1.3: Antenna and RAy3 unit RACOM s.r.o. RAy3 Microwave Link 11 Product 1.2.3. Grounding screw Grounding screw is used for a proper grounding of the RAy unit, which is necessary for its function (ensured by galvanic connection to the grounded mast through a grounding cable). One M8 screw (with standard 6-edge head) is delivered with each RAy unit. Grounding screw has two possible positions (two holes) to be mounted in. Those are located near the left and right fixing screws of the RAy unit and both are marked by a yellow grounding symbol and both are equivalent (second hole remains unused). For more information about unit grounding see Section 4.3.3, RAy unit grounding. Note Fig. 1.4: Grounding screw Grounding screw function is to ensure proper grounding of the RAy unit (by a grounding cable), not for mechanical fixing of the unit. 12 RAy3 Microwave Link RACOM s.r.o. 1.3. Ethernet + power interfaces This chapter describes interfaces for user data transfer and power sourcing of the unit, as described on the picture and characterized in the table below. Remaining interfaces for service purposes are described in next chapter Service interfaces. Product Fig. 1.5: Slots ETH1+POE, ETH2 Slot Function Gigabit metallic Ethernet + Power over Ethernet (PoE) port ETH1+POE This port is capable of powering the unit with any PoE power source working ac-
cording to IEEE 802.3at standard. Passive PoE from 20 to 60 V is supported (if DC input is required, it could be injec-
ted through this connector - the voltage range is identical: from 20 to 60 V). Slot for user exchangeable SFP module A wide range of fibre optics Ethernet modules is available. Both single or dual mode transceivers can be used. An SFP module with metallic RJ45 interface can also be used. The SFP LED Located on SFP, just next to connectors. It is controlled by SFP module. Its function is specific for each SFP module. The typical behavior is an indication the received signal from the optical or metallic link to be within operational range. ETH2 Note A set of all necessary bushing parts are delivered with each RAy unit - see a description of this standard basic accessory ACS-RAy3. Additional bushing options for installation of longer connectors or other equipment are available as well. For bushings installation see Section 4.4, Connectors assembly and disassembly. All accessories offered by RACOM for proper installation of the complete RAy link setup (in-
cluding proper grounding) are tested for compatibility with RAy unit. See accessories listed in overview and described in details. RACOM s.r.o. RAy3 Microwave Link 13 Product Important All bushings and plugs (including the original plugs in the flanges) must be fitted with O-rings and carefully tightened. Otherwise, the unit is not protected against moisture intake through connectors and can not offer guaranteed functionality. 1.3.1. Ethernet 1, PoE - RJ45 connector ( ETH1+POE ) RJ45 socket connector marked ETH1+POE is a standard 10/100/1000Mbps metallic Ethernet port. One plastic RJ45 plug for CAT5e and CAT6 cables is delivered with each RAy unit, ready to be punched to an Ethernet cable. Higher quality and CAT7 compatible RJ45 plugs are available from RACOM as well see for example item CON-RJ45-TLG-CAT6. This port can be optionally used for power sourcing the unit by PoE (Power over Ethernet). Both an active PoE power supply (compliant with at least IEEE 802.3at stand-
ard known also as PoE plus) and a passive PoE power supply (with voltage range 20-60 V) are supported. Technical parameters of PoE power input:
Supported voltage range is 20 to 60 V, both polarities are supported. For Ray unit booting the minimum re-
quired voltage is 21 V (to prevent booting with discharged 24 V battery). Internal RJ45 pins wiring is:
(V+) ... 1,2,4,5
(V-) ... 3,6,7,8 It is possible to use all 8 pins or only 4 pins. Use:
either 4,5 (V+) and 7,8 (V-) or 1,2 (V+) and 3,6 (V-) or both simultaneously Fig. 1.6: RJ45 Ethernet connector All contacts of RJ45 connector are galvanically separated from RAy unit. It ensures galvanical separation for any kind of PoE power supply as well as for DC power sourcing (made through OTH-DC/RJ45). More information about usage and installation of available power options can be found in Section 4.6, Power supply and Section 4.5, Grounding and overvoltage protection. 14 RAy3 Microwave Link RACOM s.r.o. Product 1.3.2. SFP slot ( ETH2 ) ETH2 is a standard SFP slot for 10/100/1000 Mbps Eth-
ernet SFP modules, user exchangeable. Both fibre optic and metallic Ethernet SFP modules are supported. For optical both single and dual mode fibre optics Ethernet modules (= 2 or 1 fibers) can be used. CSFP modules are not supported. RACOM offers all mentioned types of SFP modules, tested to be RAy compatible as a standard ac-
cessory. The SFP status LED is located just next to the slot. It is controlled by SFP module. Its function is specific for each SFP module. The typical behavior is an indication the re-
ceived signal from the fibre optic or metallic link to be within operational range. Do not remove the smaller plastic screw next to ETH2 label. It is part of the cabinet and assures pressure equalization outside and inside. Important Fig. 1.7: SFP slot It is strongly recommended to use a high quality SFP module with industry temperature range. The SFP modules listed in Accessories are thoroughly tested by RACOM and are guaranteed to function with RAy units. It is possible to use any other SFP module, but RACOM cannot guarantee they will be completely compatible with RAy units. RACOM s.r.o. RAy3 Microwave Link 15 Product 1.3.3. DC power ( using ETH1+POE ) Direct DC power source can be used to power the RAy3 unit. Slot ETH1+POE allows to use the OTH-DC/RJ45 as a DC connector. It is equipped by 2 terminals (each 1.5 mm2 / AWG 14) with screws to ensure a perfect con-
nection with cooper DC power cable. Its other end is then fitted into RJ45 connector slot ETH1+POE in the RAy unit. Supported voltage range is 20 to 60 V, both polarities are supported. For Ray unit booting the minimum required voltage is 21 V (to prevent booting with discharged 24 V battery). Power input is galvanic separated inside RAy unit. Optional grounding of DC cable should be connected directly to the mast or to the Grounding screw on RAy chassis, to ensure proper grounding of the cable. For grounding to the mast use suitable grounding kit for example see Grounding in section Accessories. More information about DC power sourcing possibilities and installation can be found in Section 4.6, Power sup-
ply. Fig. 1.8: Power supply connector Fig. 1.9: Power via an DC-RJ45 adapter 16 RAy3 Microwave Link RACOM s.r.o. Product Fig. 1.10: Power via DC-RJ45 adapter Note DC-RJ45 adapter occupies ETH1+POE port. When used, Ethernet connection to the unit has to be made through ETH2 port. Possible solutions are:
If fiber optic Ethernet is used (using the correct type of SFP module), RAy3 unit is powered by DC through the DC-RJ45 adapter. If a metallic Ethernet has to be used together with DC power source, then metallic SFP module in ETH2 SFP slot is one of valid solutions. Other valid possibility how to power the unit using DC power source is to use passive PoE in-
jector or active PoE power supply with DC input and deliver the power to RAy3 unit through Ethernet cable with RJ45 connector plugged in to ETH1+POE slot. Fig. 1.11: SFP possibilities when direct DC power is used RACOM s.r.o. RAy3 Microwave Link 17 Product 1.4. Service interfaces Slot S is shortcut of "Service". It contains system connectors standard USB port and a pair of contacts for RSS voltage output (red + gray ones). Also HW button and Status LED are located there. Fig. 1.12: Slot S Slot Function USB service connector For USB/WiFi or USB/ETH adapters, see Section 1.4.1, USB connector ( S ) RSS voltage output Red and green connectors (for example 0.547 V means RSS = 54.7 dBm), see Fig. 1.16, RSS voltage contacts S HW button For service purposes: Internal backup or Factory settings, see Section 5.6.1, Maintenance Status LED Visible through semitransparent plug, see Section 1.5, Status LED ( S ) 18 RAy3 Microwave Link RACOM s.r.o. Product 1.4.1. USB connector ( S ) USB-A port is designed for access to RAy management through USB/WIFI adapter or USB/ETH adapter plugged in to. More information about installation and configuration of available adapters can be found in Quick Guide and in Section 5.4.3, Service access (part USB Accessories). Note Only RACOM recommended adapters are supported. See section USB adapters. 1.4.2. Service WiFi - optional (using USB S) Each RAy3 unit is equipped with the service WiFi interface from the factory. It is realized by standalone WiFi module inserted in to the USB connector in slot "S". WiFi can be used solely for unit management (no user traffic can be transmitted by using this WiFi connection). WiFi module can be disabled in FW (WiFi module is out of power then) or manually unplugged. In both cases the results are identical - no WiFi is possible. Management of the WiFi port is described in Section 5.4.3, Service access (part USB Ac-
cessories). 1.4.3. Service Ethernet - optional (using USB S) RAy3 unit can be equipped with the service Ethernet interface as an option. It can be used solely for unit management (no user traffic can be transmitted using this Ethernet connection). Optional Eth adapter (ordering code OTH-USB/ETH-XA) can be inserted in to the USB connector in slot "S" (instead of WiFi module). Management of this Ethernet port is described in Section 5.4.3, Service access (part USB Accessories). Fig. 1.13: USB connector Fig. 1.14: USB WiFi adapter Fig. 1.15: Ethernet adapter RACOM s.r.o. RAy3 Microwave Link 19 Product 1.4.4. RSS voltage contacts ( S ) RSS voltage output connectors are located in slot S aside USB connector. This pair of contacts (red + green ones) al-
lows to connect a voltmeter (pin diameter 2 mm) to the RAy unit and measure RSS value transformed to the voltage out-
put. RSS (Received Signal Strength) is a basic parameter used for directing antennas to the optimal direction. RSS output voltage is calibrated to be proportional to actual RSS dBm
(for example 0.547 V means RSS 54.7 dBm). Thus a standard digital voltmeter allows to see RSS value in a digital form interactively during the antenna alignment. More inform-
ation about RSS voltage output usage is in Section 4.7.2, Directing antennas (part Voltmeter) together with several alternative ways to get this value by other methods. 1.4.5. HW button ( S ) It is located in a small hole next to USB connector. It can be pushed by any tiny blunt thing with the diameter up to 2 mm. Its length has to reach about 7 mm in to the hole. (It can be ball pen cartridge both ends work on the thin one, match, toothpick, etc.). Important Usage of very sharp things for pushing the HW but-
ton (like needle, edge clip etc.) may destroy the contact inside RAy unit! Such a button destruction is not covered by warranty. Fig. 1.16: RSS voltage contacts The button supports multiple functions, which are activated dependent on the state of the unit when the button is pushed and the length of the push:

Note Please your supplier to ensure completeness of your product delivery for the individual link situation, applicable spectrum regulations, local security requirements, type of power sourcing, grounding, etc. Important RACOM does not have any responsibility for improper use of any offered device. It is customers full responsibility to check technical parameters of all ordered items and to use and configure them in accordance with their purpose. It is also customers full responsibility to respect all requirements applicable at the site of installation. 1.7.1. RAy units There are several different ordering codes for each HW model of RAy3 units. They differ in some properties like working frequency, encryption HW acceleration, factory defaults and limitations built in to units in the factory like limitation of Tx power or prevention to use any form of encryption (not changeable later by license keys or by a user). The structure of RAy3 ordering code7 starts with detailed identification of the HW model (first 9-11 symbols), which are also printed on RAy3 Product label." The structure of HW model identification is:
Fig. 1.19: Ordering information Trade name + Gen. Band RAy3 Frequency band in GHz Possible values: 17, 24 5 http://www.racom.eu/eng/products/microwave-link.html#order-codes 6 https://webservice-new.racom.eu/main/eshop.list 7 https://www.racom.eu/eng/products/m/ray3/product.html#obj_kod RACOM s.r.o. RAy3 Microwave Link 23 Product Var. FRQ Type Code Important Designation of product variant, if it is used. More variants can be used within one unit, i.e. more letters can be on this position. These variants cant be ordered and included in the unit later on. Possible values:
none (position not used) means same as X N no encryption HW, encryption will never be possible (neither HW nor SW) E no encryption HW S encryption HW installed, MTU 2048 Bytes (only RAy3-24) X encryption HW installed, MTU 10240 Bytes R reduced RF output power -30 to -15 dBm (always in combination with N, E, S or X) Frequency Possible values:
L unit transmits on lower part of the band U unit transmits on upper part of the band Note: L/U indicates TX default, which can be changed. Both units have the same HW for lower and upper unit. Specific product type for which type approvals like CE, FCC etc. are issued. Possible values:
RAy3-17, RAy3-24 Detailed HW identification of the unit printed on Product label on the housing. Note: SW keys and Optional accessories are not HW dependent and can be ordered later on, so they are not printed on Product label. The processor included in the unit variant S and X uses a encryption module listed as 5A002 a.1 in the COUNCIL REGULATION (EC) No 428/2009, setting up a Community regime for the control of exports, transfer, brokering and transit of dual-use items. Units are subject to export control when exporting outside the European union, according to national, EU8 and US law. RAy3 microwave link has to be ordered together with SW feature key for initial capacity and optionally with a bundled DC power adapter. Those appear in ordering codes in brackets just after first 9-11 symbols of the detailed HW variant (lasting by -L or -U and printed on unit Product label as item Code). Those functionalities and options could be added, erased or changed by a user later on. For detailed description of the ordering code structure see RACOM web9. Note The proper pair of Lower (L) and Upper (U) units should be selected when ordering the mi-
crowave link. The difference between L and U code is only in default factory settings, which are different for each side of the link. Unit marked with L is set for transmission on lower fre-
quency (and receive on higher one), while unit marked with U is set for transmission on higher frequency (and receive on lower one). This allows the link to be established without any initial manual settings just by powering up both units at factory defaults (see Quick Guide). 8 http://ec.europa.eu/trade/import-and-export-rules/export-from-eu/dual-use-controls/index_en.htm 9 http://www.racom.eu/eng/products/microwave-link.html#order-codes 24 RAy3 Microwave Link RACOM s.r.o. Product 1.7.2. Capacity keys RAy units allow to pay only for purchased transmission capacity (pay as-you-grow concept). Activation keys could be purchased together with the unit or later at RACOM E-shop10. Each key is generated for specific S/N of the unit and the purchased capacity. It unlocks all combinations of channels and modulations up to the purchased capacity. Once installed, a specific feature or function of the unit is allowed. Feature keys could be erased or upgraded. See Configuration / Feature keys for more details. Several types of SW feature key are available for RAy units:
Bundled capacity (ordered together with RAy units - see previous chapter) Separately purchased capacity feature keys (see below) Upgrade capacity feature keys (see below) Maximum transmitted data capacity can be limited by a SW feature key. Capacity feature key defines allowed combinations of channel width and modulation for transmitting channel according Capacity SW keys table11. The Capacity feature key limit applies for transmitted data on the unit where the key is installed. It means, that for asymmetrical capacity keys could be different for each side of the link. Capacity feature keys could be purchased bundled with RAy3 unit (and installed in the factory) or standalone or as a capacity upgrade key (both installed by user). Every Capacity feature key could be upgraded. Separately purchased capacity feature keys Keys purchased separately and installed by user. Tab. 1.4: Capacity keys code scheme For available ordering codes see RACOM web12. Note RACOM is able to generate customer specific Capacity feature keys on special request. Upgrade capacity feature keys Keys purchased separately and installed by user. 10 https://webservice-new.racom.eu/main/eshop.list 11 http://www.racom.eu/eng/products/microwave-link.html#scalability 12 http://www.racom.eu/eng/products/microwave-link.html#order-codes RACOM s.r.o.

Features activation RAy units allow to pay only for purchased features (pay as-you-grow concept). Activation keys could be purchased together with the unit or later at RACOM E-shop14. Each key is generated for specific S/N of the unit and the purchased feature (or a set of features). Once installed, a specific feature or function of the unit is allowed. Feature keys could be erased or upgraded. See Configuration / Feature keys for more details. Available feature activation keys are listed in following table:

Product Fig. 1.20: Example of production label Note A link should consist from a pair of -L and -U units (L and U are always a last letter in Code printed on production label of each unit). It would ensure the link is automatically established after factory defaults (to simplify initial setting of the unit). 1.7.5. Certified Accessories Ordering codes for all accessories certified by RACOM to work properly with RAy units, are listed in Section 2.1, Overview and on Accessories section15on RAy web sites. RACOM resells those on RACOM E-shop16 and in Section 2.2, Details provides full information where to buy them directly from original suppliers. Note Accessories are necessary to be added to RAy units to allow a proper functionality of the whole microwave link.

Pre-installation check out Installation (Chapter 4.) Advanced configuration (Chapter 5.) Troubleshooting (Chapter 8.) Pre-installation Checklist Default settings for L and U units are chosen to allow delivered units to automatically establish a link without unpacking RAy3 units from the box. It is enough to open the boxes and power both RAy units up (by PoE or DC power supplies). It allows users to comfortably set up basic parameters necessary for the installation in the lab and thus shorten the time on the tower or roof to a minimum. Following text provides a guide how to optimally arrange the workplace, how to setup the link and which parameters are good to be set up before the installation outside. Default factory settings define the initial link to be established on the most narrow channel, strongest modulation and lowest available Tx power (in RAy3 case those are 3.5 MHz channel, QPSK_S modu-
lation and Tx power = -30 dBm). Complete default settings are described in section 10 Technical parameters. Note RAy3 default factory settings allow to install both units on the mast and establish the short link without prior manual configuration. Just the distance has to be very short due to Tx power set to the minimum for the unit (-30 dBm on RAy3-17 and RAy3-24). Typically, Tx power has to be increased to a reasonable level (or even to a maximum) before link alignment. Fig. 3.1: Workplace for link testing and configuration 38 RAy3 Microwave Link RACOM s.r.o. Step-by-step Guide Take the following steps to link together both delivered RAy3 units and to establish a connection between them and PC or tablet or mobile and perform a basic setup:
Open both boxes and double check that both RAy3 units are turned OK, so waveguides are heading to each other. Connect power sources (PoE or DC) to both RAy3 units (using slot ETH1+POE). Wait about 30 seconds until both units boot up and the link is established. The green light should be visible on both units through transparent plug on slot S. Until a WiFi password is set, red light periodically flashes together with green light - see Section 1.5, Status LED ( S ). Connect by WiFi or by Ethernet cable (plugged in to LAN input on PoE power supply or in to Eth port on USB/ETH adapter) to one of those two units. Units linked together allow effectively set all IP ad-
dresses, passwords, security keys, feature keys, users, etc. from one side of the link. If WiFi is used, then just select which WiFi to connect to. IP address of your PC or laptop is set automatically by DHCP. If Eth over USB port is used (through USB/ETH adapter OTH-USB/ETH-XA), IP address of your PC or laptop is set automatically by DHCP as well. If Eth connection to one of data ports on RAy3 (ETH1 or ETH2) is used, then the IP address on your PC or laptop has to be set manually to establish a working connection. See Quick Guide for the complete list of IP addresses to use. Enter a web management of the unit and configure everything you like to change to be ready for outside installation. Following parameters are typically set in this phase:
IP addresses and VLANs passwords security keys feature keys users WiFi password and behavior Tx and Rx frequencies (if known in advance) Higher Tx power (to be ready for antenna alignment) see section Important below Note This setup can be used for link configuration, however full radio performance can't be expec-
ted (high modulations, full Tx power range, etc.) because standard conditions between units
(antenna interface, polarization planes, free space attenuation) are not met inside the box. High TX power does not lead to better RX signal quality, because the receiver input can be saturated with too strong signal - see Overexcited receiver. Until a WiFi password is set, red light periodically flashes together with green light - see Section 1.5, Status LED ( S ). Important Maximum secure Tx power for RAy units inside the box is 0 dBm. Higher Tx power risks the damage of sensitive input circuits!
If you need to configure higher Tx power to be ready for antenna alignment during installation on the mast, you first have to turn units in to position where waveguides are not heading to each other, so reasonable attenuation is ensured. Secure is for example to put RAy units RACOM s.r.o. RAy3 Microwave Link 39 Step-by-step Guide in parallel in to a direction without any metal material in front of the microwave beams (it could reflect waves back to units). Maximum time units can be powered up inside the box is 10 minutes (standard room tem-
perature expected). Longer time may lead to the unit overheat! If more time is needed for configuration, units have to be unpacked from boxes. 40 RAy3 Microwave Link RACOM s.r.o. Step-by-step Guide 3.1. Service access The RAy3 link is supplied with a default configuration of access parameters:
For Ethernet access through RJ45 or SFP ports:
Unit L has the service IP address 192.168.169.169 and mask 255.255.255.0 Unit U has the service IP address 192.168.169.170 and mask 255.255.255.0 For WiFi or Ethernet access via USB/WiFi or USB/ETH adapter:
Both units have service IP address 172.17.17.17 and mask 255.255.255.0 For Ethernet access through RJ45 or SFP ports an IP address has to be set on your PC that is within the mask, e.g. 192.168.169.180. For WiFi or USB/ETH access an IP address for laptop or mobile or tablet is set automatically by DHCP (enabled by default). Then open the HTTP or HTTPS configuration interface, e.g. https://192.168.169.169 or ht-
tp://172.17.17.17 Access is allowed over HTTP, HTTPS or SSH. The default username is "admin" and the password is also "admin" (it is strongly recommended to change it). See Configuration / Link settings / Service access / USB accessories chapter for detailed information. The Antenna Alignment Web Tool can also be used for antenna direction alignment. It can be accessed via a web browser utilizing IP addresses with /tk at the end (e.g. http://172.17.17.17/tk for WiFi or USB/ETH adapter or http://192.168.169.169/tk or http://192.168.169.168/tk for ETH1/ETH2 ports). When connection has been established, use the Service access menu to customize access parameters. Default management IP addresses should be replaced with well-chosen operating addresses. Default can lead to network problems later. The menu contains parameters for the entire link, both for the Local and remote Peer units. If a connec-
tion has been established, both sets of parameters have been set. While working with an isolated unit, only Local parameters are functional for the currently connected unit. Note If the link is OK and there are no parameters shown of the station Peer, it is necessary to click on Refresh. Follows the description of basic settings. Pictures in following sections show default factory settings for L unit and RC info rcinfo20_250_default:XXX. Default settings for unit U (for opposite side of the link) would be adequately exchanged. Values for other RCinfo may be different as well (differences typically refer to frequencies and Tx power as they are allowed by authorities for the actual band and a region). After entering values on the screen always save the content by clicking on Apply. Note If there is any problem with HTTPS certificate after completing the firmware upgrade, please see the Annex Https certificate for further steps. RACOM s.r.o.

Station location for easier inclusion the network hierarchy, it is possible to enter the stations location Fig. 3.3: Configuration Menu Link settings / General For full explanation of all possibilities of this screen see Section 5.4.1, General. RACOM s.r.o. RAy3 Microwave Link 43 Step-by-step Guide 3.1.3. Setting Ethernet access parameters Menu Link / Service access / Services Those settings are necessary to make new units accessible within target Ethernet network. Typically, all following parameters should be set according to both networks IP addressing, routing, planned access methods for data and for management, etc.:
IPv4 address enter a valid IP address to access the unit. The default IP address has to be replaced with a valid address. Keeping the default address will probably lead to future problems in the network. Netmask enter the network mask. Gateway if necessary, enter a gateway, otherwise leave blank Enable access protocols that you are going to need. For security reasons, do not enable more than is necessary. HTTP(S) allow access to the web interface. Telnet enabling access to the CLI interface using telnet protocol. SSH enabling access to the CLI interface using SSH protocol.

Step-by-step Guide 3.1.4. Creation of users Menu Link / Service access / Users It is recommended to create user accounts managed by the main user already in this phase (for example a user with rights limited to read-only access). Following actions are available:
Edit - enter the menu. New password choose a password and enter it. Confirm password enter the password again to confirm. Fig. 3.5: Configuration menu Link settings / Service access / Users For full explanation of all possibilities of this screen see the section called Users. RACOM s.r.o. RAy3 Microwave Link 45 Step-by-step Guide 3.1.5. Applying Feature keys Menu Maintenance / Feature keys The firmware of the microwave link is capable of controlling several features (for example the maximum user data speed, maximum Tx power, etc.). It is recommended to install all separately purchased feature keys prior to physical installation to allow all expected features of the link to be usable after the install-
ation. Fig. 3.6: Configuration menu Maintenance / Feature keys Note Speed keys purchased with the unit are installed in the factory (and can be double checked within this menu). Key for limited Tx power is not installed except specifically ordered. If RCinfo limits the maximum power, it can not be overruled by feature key with the higher Tx power. For full explanation of possibilities of this screen see the section called Feature keys. 46 RAy3 Microwave Link RACOM s.r.o. Step-by-step Guide 3.1.6. WiFi settings Menu Link / Service access / USB accessories Go to menu Link Settings / Service Access / USB accessories and enter WiFi password or disable WiFi completely. Standard settings are that Enable on Air link loss is ON (when the link is down, WiFi is activated; when link is OK, WiFi will be deactivated in few minutes) and Force Enable is OFF (activates WiFi permanently). Passphrase has to be set, otherwise the WiFi is unsecured and system warning is active. Fig. 3.7: Configuration menu Link settings / Service access / USB accessories Note If you access the unit over WiFi, do this step as last action before reboot (as the WiFi connection will be interrupted and new connection with new password would be required to continue the work). For full explanation of possibilities of this screen see the section called USB accessories. RACOM s.r.o. RAy3 Microwave Link 47 Step-by-step Guide 3.2. Basic link configuration Default radio parameters depend on the specific type of link and the specific channel allocation table. Channels are typically set in the lower part of the band, the smallest bandwidth, QPSK modulation, and low power. Both units in the pair should be capable of immediate communication. If it is possible to work with these radio parameters at the installation location, the link can be activated. On an operating link the required operating parameters can then be set up. If a change in the parameters is necessary, it is done in the menu Link settings / Radio and saved by clicking Apply. This applies when working on both units simultaneously if they are connected, otherwise each unit is configured individually. When configuring units individually, pay attention to correct settings of duplex pair for channels TX and RX. For example, if one station has TX channel L1, then the second station must also have the channel RX L1. 3.3. Link test Verify the functionality of the radio link:
Switch in screen Status / Brief. Status Bar displays Link: Ok. If the alarm message appears at Local or Peer, this doesnt necessarily mean there is a problem. The message indicates that the limit at any of the monitored parameters has been exceeded. Essential is the "Link: Ok" message on the status bar. The Status screen contains values for both Local and Peer units. N/A next to Peer indicates that the data from the Peer unit has not been transferred. If Link is Ok, simply click Refresh at the bottom of the screen and Peer data will be updated. Menu Status / Detailed / Radio indicates link RSS and MSE values, in case of ACM also the selected modulation and Netbitrate. If the ATPC function is enabled (menu Link settings / Radio) it also indic-
ates instantaneous / max. allowed power and for MSE and RSS values it indicates immediate / target value size. Menu Tools / Live data / Bar indicators displays current size of RSS, MSE and BER. Menu Tools / Programs / Ping allows you to send a ping test to the selected IP address. Try out the possibility of modulation:
Modulation ACM. In menu Link settings / Radio enable ACM. Set the TX modulation parameter to the required maximum value. In menu Status / Brief / Radio you can monitor (Refresh or Start) changes in used modulation based on the instantaneous MSE signal quality. To set a fixed modulation go to Link settings / Radio, switch off ACM and set the TX modulation to a value from the range of QPSK through 256-QAM based on the results of the previous test. If you choose modulation higher than allowed by MSE, the connection will be lost. Status Link will lose its Ok value. Both units will need to be moved closer to resume the link. If this is not possible, use the Ethernet to access each unit individually and set the basic modulation QPSK. Verify the functionality of the entire link:
If possible, connect user devices to both RAy units over PoE and test mutual communication. Another way of testing this is to connect a PC to the other unit and send a ping from one PC to the The minimum variant of this test is to use an Ethernet cable connection from the PC connected to the local RAy to the PC connected to the remote RAy and test communication between both units over Ethernet. This will verify Ethernet functionality. other. 48 RAy3 Microwave Link RACOM s.r.o. Prepare installation configuration:

Antenna mounting Antenna mounting depends on the antenna vendor, antenna type and the size of the chosen antenna. The result of any antenna installation is that it is fixed to the mast, pointing to the right direction and its waveguide and fixing screws are ready for mounting RAy unit to it. Fig. 4.2: Antenna mounting 50 RAy3 Microwave Link RACOM s.r.o. Installation Fig. 4.3: Fixing screws Common for all antennas is a holder which ensures:
fixing of the antenna to the mast flexibility in two planes (necessary for antenna adjustment to the proper direction). Each holder allows at least 2 methods of mounting antenna on the mast tube:
right-side mounting left-side mounting Following sections describe in detail installation of antennas, mounting kits and/or flexible waveguides, so the antenna is ready for mounting RAy unit to it. Choose below a chapter relevant for your antenna supplier and installation manual according to antenna type and size. Note Each antenna allows RAy unit to be mounted on it with horizontal or vertical RX polarization. This is discussed in detail in Section 4.3, RAy unit mounting. 4.2.1. LEAX-RAy antenna mounting Mounting instructions for each LEAX-RAy antenna are shipped with each antenna. Identical mounting instructions are available within RACOM RAy download1 section, on our website. See list below:

(same for all sizes). The RAy interface is part of each LEAX-RAy delivery (one interface set per antenna). It needs to be mounted to each antenna according to the instruction manual before mounting the RAy unit. Four pcs M8x30 (Allen) screws to mount the RAy unit to the antenna are also part of the antenna delivery. Note 0.9m and 1.2m LEAX-RAy antennas on windy sites (max wind speed above 50 m/s) has to be installed with optional struts. They allow to increase operational wind speed up to 65 m/s
(instead of 50 m/s respectively 55 m/s). They also allow to use tower pipe 50-120 mm (instead standard 90-120 mm). Consult LEAX website9 for exact parameters and additional info. Ensure the pin lubrication is completed during assembly. 4.2.2. Jirous antennas mounting Mounting instructions for Jirous antennas are available on the manufacturer's website http://en.jirous.com. Mounting is also described in detail on RACOM RAy download10 section:

Strut allows to increase operational wind speed (typically up to 65 m/s). Consult Jirous website13 for exact parameters and additional info. Ensure the pin lubrication is completed during assembly. 4.2.3. Other antennas mounting Antenna which do not have a direct interface to RAy needs also a proper antenna mounting kit or a flexible waveguide with a mounting kit for it. Such interface has to be installed prior to RAy unit install-
ation to the antenna. Antenna mounting kit can be ordered as an accessory part (one per antenna). It has to be chosen ac-
cording to selected band and antenna vendor - see Overview of currently available types. Any other antenna can be connected to the RAy by standard flexible waveguide. RACOM offers mounting kits
(RAy holders) for different flexible waveguides (see Accessories and the picture Flexible waveguide). 6 https://www.racom.eu/download/hw/ray/free/eng/04_1_anteny/ANT-LEAX-1200-inst.pdf 7 https://www.racom.eu/download/hw/ray/free/eng/04_1_anteny/ANT-LEAX-1200-strut-inst.pdf 8 https://www.racom.eu/download/hw/ray/free/eng/04_1_anteny/ANT-LEAX-RAy-inst.pdf 9 https://www.leax-arkivator-telecom.com/en/products/microwave-antennas.html 10 https://www.racom.eu/eng/products/microwave-link.html#download 11 https://www.racom.eu/download/hw/ray/free/eng/04_anteny/ANT-JRM-inst.pdf 12 https://www.racom.eu/download/hw/ray/free/eng/04_1_anteny/ANT-LEAX-900-strut-inst.pdf 13 http://en.jirous.com 52 RAy3 Microwave Link RACOM s.r.o. Installation Standard mechanical tools are enough to install each of those accessories. Antenna mounting kit for Arkivator antennas Items "ANT-ARK-KIT-xx" (where xx is the band) fits all traditionally produced Arkivator antennas (from company Arkivator, acquired by LEAX Group) as well as today produced Arkivator antennas from company LEAX Arkivator Telecom sold without RAy interface. NOTE:
All LEAX-RAy antennas listed in the RACOM portfolio contain specific RAy interface and thus no mounting kit is required. Antenna mounting kit for Andrew antennas Items "ANT-ANW-KIT-xx" (where xx is the band) fits most of Andrew antennas manufactured by CommScope with specific vendor's interface unmounted. RAy3-17 and RAy3-24 need Dual polarized antennas. for 17 GHz band use ANT-ANW-KIT-17/18 and order the following dual-polarized antenna types:
30 cm 60 cm 100 cm VHLPX1-18W/A VHLPX2-18W/A VHLPX3-18W/A NOTE:
The antennas labelled for 17.700 - 19.700 GHz band are also OK for 17.100 - 17.300 GHz band
(confirmed by CommScope). for 24GHz band use ANT-ANW-KIT-24 and order the following dual-polarized antenna types:
30 cm 60 cm 100 cm VHLPX1-26W/A VHLPX2-26W/A VHLPX3-26W/A NOTE:
The antennas labelled for 24.250 - 26.500 GHz band are OK for 24.000 - 24.250 GHz band (con-
firmed by CommScope). NOTE:
Ordering codes with "-W/A" at the end means one of suitable types of waveguide (vendor's interface), must be unmounted before installation of RAy antenna mounting kit. Ordering codes with "-GDC" at the end means no vendor's interface, so nothing needs to be unmounted in such a case. If there is a requirement to connect different type of antenna (for example some newer antenna type), it is possible to modify the existing adapter to meet new requirements. Flexible waveguide Flexible waveguide mounting kit can be ordered as an accessory part. RACOM s.r.o. RAy3 Microwave Link 53 Installation Fig. 4.4: Flexible waveguide assembly Flexible waveguides themselves are not offered by RACOM - please consult your antenna supplier. Ensure the pin lubrication is completed during assembly. 4.3. RAy unit mounting RAy unit can be attached to several different models of antennas from several vendors. Installation of RAy unit on to LEAX-RAy or Jirous antennas or to any other antenna through proper RAy mounting kit (eventually with flexible waveguide) is very simple and it is identical for all antennas and mounting kits. Installation starts with the lubrication of antenna pivot, followed by fixing the RAy unit in a proper position to the antenna and finished by unit grounding to the mast as described in following sections. 4.3.1. Lubrication of the antenna pivot Before fitting the RAy bushing to the antenna pivot ensure the "O" ring (part No. 1) is in the correct position. It is also essential to prevent moisture getting in between these two parts. This moisture could cause oxidation which would complicate disassembly of this mechanical coupling in the future. For this reason we need to treat these surfaces with the grease which is supplied in the box marked
"SILIKONOVE MAZIVO / SILOCONE GREASE". If you use a different grease for lubrication then it should be a Teflon or a silicon grease. Fig. 4.5: Grease points on the antenna pivot and RAy unit bushing Lubricate both the internal area of the bushing on the RAy unit (2) and the "O" ring (1) with a thin even layer that allows the pin to slide easily into the bushing without damaging the "O" ring. The layer has to be really thin and even to ensure no grease is pushed in to the waveguide. A little bit more grease 54 RAy3 Microwave Link RACOM s.r.o. may only be applied in the area (3) beyond the "O" ring on the antenna pin to optimally fill the small gap (max. 0.1 mm) between the pin and the bushing to prevent leakage of moisture and water into the unit. Installation should be carried out according to the antenna installation instructions. Installation A tub of grease is supplied with each RAy unit. Important Lubrication is a very important assembly step for every RAy unit. Failure to lubricate the unit can lead to operational and assembly complications. Fig. 4.6: Silicone grease 4.3.2. RAy unit mounting to the antenna Each antenna allows RAy unit to be mounted on it with different polarization:
horizontal TX polarization vertical TX polarization Fig. 4.7: Horizontal and vertical TX polarization see the arrow sign In all cases mount the unit with the connectors facing downwards at an angle. Note RAy3-17 and RAy3-24 links need one unit to be installed with vertical polarization and the other unit with horizontal polarization because these units use cross polarization. RACOM s.r.o. RAy3 Microwave Link 55 Installation Fig. 4.8: RAy3 unit with antenna (left-side mounting and horizontal polarization) RAy unit is fixed to the antenna by 4 pcs M8x30 (Allen) screws, which are part of the delivery of each antenna or each mounting kit. Those should be partially unscrewed so that the unit can be slid on to them. Then check whether the "O" ring is correctly fitted on the antenna pin, and make sure it is not damaged and has been lubricated with grease see Section 4.3.1, Lubrication of the antenna pivot above. Then remove the protective plastic cover from the central pin of the antenna and fit the unit flange
(located in the center of flat part of RAy unit, across the holder) to it carefully not to damage the "O"
ring. Once the RAy unit is plugged to the antenna pin, turn RAy clockwise so its screw-holders fit the right position for all 4 screws. Carefully ensure the correct polarization of the unit and secure the RAy unit in place with all four bolts. Finally, gently tighten the bolts with a No. 6 Allen key. Important Gently tightening all 4 screws is enough. Do not over-tighten any screw, it may damage the protective color surface of the aluminum unit (enforcing corrosion processes) and in the case of an extreme force also deformations of the RAy aluminum cover may happen. Later de-in-
stallation of the unit then becomes difficult. Please ensure that all 4 screws are tightened equally during tightening and the gap between RAy screw-holders and spacers on all 4 sides of the RAy unit is approximately identical. Too strong tightening of one or 2 screws on one side of RAy unit may lead to the deformation of the sensitive zone of the waveguide between the antenna and the unit, resulting in weaker radio parameters. Even a small residual gap between RAy unit and the antenna is OK, because important is a good connection of waveguide it is good enough even with screws gently tightened. NOTE:
on older LEAX-RAy antennas (shipped during the year 2017) the residual gap under each screw-holder on RAy and antenna body may be up to 1 mm. 4.3.3. RAy unit grounding RAy unit has to be properly grounded, otherwise it can not be guaranteed its function and it can be even damaged. Grounding connection through antenna and its holder is not enough (due to color surface, oxidation etc.), thus a separated grounding is required to ensure the perfect galvanic connection. Important The RAy unit has to be grounded before connecting to the power supply and/or to the user network. 56 RAy3 Microwave Link RACOM s.r.o. Installation Typically the unit is grounded to the antenna mast, which has to be properly grounded (according to Fig. 4.19, Grounding installation 1 and Fig. 4.20, Grounding installation 2, where unit grounding to the antenna mast is marked by yellow-green cable). The RAy unit is grounded to the flange at the fixing screws using an M8 screw. An insulated copper cable with a minimum cross-section of 6 mm2 terminated with a terminal lug is used as a protective conductor. The conductor should have a green/yellow plastic cover along its whole length. The RAy grounding kit can be ordered as an accessory (see Chapter 2. Accessories) containing a grounding terminal ZSA16, 40 cm grounding strip 15 mm wide, and 100 cm of cable with grounding lugs. For in-
structions on installing terminals see the datasheet RAy grounding kit14. The antenna must be installed by a qualified person. Properly installed unit grounding kit (from RACOM accessory) is documented on photos below. Fig. 4.9: Protective conductor at the RAy unit Fig. 4.10: Grounding the RAy unit Fig. 4.11: RAy grounding kit Fig. 4.12: Protective conductor at the mast on a ZSA16 terminal 14 http://www.racom.eu/download/hw/ray/free/eng/07_prislusenstvi/ZSA16-en.pdf RACOM s.r.o. RAy3 Microwave Link 57 Installation 4.4. Connectors assembly and disassembly The unit is equipped with 3 connector slots described in detail (including connectors pin-outs) in Sec-
tion 1.3, Ethernet + power interfaces and Section 1.4, Service interfaces. Use only standard coun-
terparts to these connectors. Fig. 4.13: Slots ETH1+POE, ETH2 Fig. 4.14: Slot S A set of standard bushing and plugs is delivered with each RAy unit as an accessory ACS-RAy3. The rubber sealing for each bushing is delivered with three different internal diameters to fit different cable diameters. The rubber is diagonally cut to enable sealing of cables with pre-installed connectors. If the lengthening of the bushing is needed use the short extension OTH-BUSH-EXT35 (adds 35 mm length, parts No.6 + No.7 on pictures below) or the long extension OTH-BUSH-EXT500 (adds up to 50 cm). Important Before connecting the RAy unit to the power supply and/or to the user network it must be grounded according to Section 4.3.3, RAy unit grounding All cables have to be secured by appropriate bushings which must be fitted with relevant O-
rings and carefully tightened in, according the instructions below. Remaining connector slots on RAy unit has to be secured by plugs (including the original plugs in the flanges). Those must be fitted with O-rings and carefully tightened as well. Other-
wise, the unit is not protected against moisture intake through connectors and can not guar-
antee unit functionality. 58 RAy3 Microwave Link RACOM s.r.o. Assembly procedure:
Installation Fig. 4.15: Short bushing assembly for metallic Ethernet with short ETH connector (for example item CON-RJ45-CAT6) Fig. 4.16: Short bushing assembly for fibre optical Ethernet with RACOM / OFA fibre optic cable Fig. 4.17: Bushing including short lengthening (for metallic Eth with longer connector or for DC-RJ45 adapter or for non-OFA fibre optic cable) RACOM s.r.o. RAy3 Microwave Link 59 Installation Put on the cable: the nut No.1, rubber sealing No.2, bushing No.3 and O-ring No.4.
(If you use extension ring No.6 with O-ring No.7 put those on the cable as well.) Attach the appropriate connector No.5 to the cable. Plug the connector No.5 into the RAy3 unit.
(If you use extension ring No.6 with O-ring No.7, lubricate its thread with grease and screw those into the RAy3 unit.) Screw the bushing No.3 with the sealing O-ring into the RAy3 unit (or into the extension if used). Move the rubber sealing (2) along the cable to fit in the bushing. Screw the nut (1) on bushing (3). Tip Practical tip: Screw the ring No.6 and bushing No.3 quote tightly, so they could not rotate when the nut No.1 is screwed (or released later on). Not doing so could damage the cable by twisting it during sealing. It can also create the issue later on when the nut No.1 is released (and ring No.6 or ring No.3 releases first). Disassembly procedure:
Release the nut No.1 Remove the rubber sealing No.2 Unscrew the bushing No.3 with O-ring No.4 (and extension No.6 with O-ring No.7). Remove the connector. Warning It is absolutely critical first to completely release and disassemble the nut No.1 and remove the rubber No.2. Failure to do so could cause the damage of Ethernet cable or fibre optic wire by cable rotation. Even connectors inside the RAy unit can be damaged. Should the rubber sealing No.2 become fastened to the cable and/or to the plastic bushings, the rubber sealing must be detached from the cable by a brute force. We suggest you use a flat screw driver to release the rubber sealing No.2. It is always better to optionally damage the bushing rather than damage a cable or components inside the RAy unit. At the outer end of the long lengthening there is necessary to use a flat ring supplied as part of the OTH-BUSH-EXT500. On other places O-rings are used. See next Figure:
60 RAy3 Microwave Link RACOM s.r.o. Installation Fig. 4.18: Bushing including long lengthening Important When using other bushing or connector than the delivered there is a danger of bad seal or damaging the connector. Interior space can be small. RACOM s.r.o. RAy3 Microwave Link 61 Installation 4.5. Grounding and overvoltage protection The proper grounding together with surge protection components should be installed on site to increase the resiliency of the whole installation against natural overvoltage situations (stimulated by storms, lightning and other atmospheric issues). Such a system has to respect local standards for grounding and electromagnetic protection, otherwise the risk of damage of the unit and/or connected IT infrastruc-
ture gets much higher. We also recommend to consult each site situation with local experts to ensure the installed grounding is enough for the actual site conditions and that the overvoltage protection of sensitive components or infrastructures is reasonably effective against typical situations on site. The rule is that every metallic component of wireless infrastructure located outside the building (in LPZ0) should be properly grounded and protected against overvoltage, especially:
grounded RAy unit itself (as described in Section 4.3.3, RAy unit grounding ) grounded all shields from all metallic Ethernet cables grounded all DC cables (shields or one wire) overvoltage protection is applied on all metallic Ethernet cables at the point of entrance to the building overvoltage protection is applied on DC cable at the point of entrance to the building All types of cables should be grounded and longer cables should be grounded in several places (outside the building every few meters). Overvoltage protective devices are available for all types of cables and usage. Accessories offered by RACOM for those purposes are listed in Section 2.1, Overview and described in detail in Section 2.2, Details . Important The unit and mast must be properly grounded before the power supply and/or the user network are connected to RAy unit. Warranty does not apply for units destroyed by surges or over-voltage (see RACOM warranty conditions at Section 10.7, Warranty ). Note Some PoE power sources, PoE injectors and DC power supplies have overvoltage / surge protection built in. Please consult the datasheets of those versus the local standards and site requirements. On sensitive sites additional overvoltage protection should / could be applied between different zones (or rooms) even within one building (for example between network center and datacenter). LPZ acronym means Lightning Protection Zone. The example and rules below are designed in accordance with regulation EN 62305. 1. Where possible the antenna should be located in an LPZ 0B protection zone with the use of a local or artificial air termination device for protection against direct lightning strikes. 2. When meeting conditions for ensuring electrical insulation (distance from the lightning conductor) in accordance with article 6.3 of this standard, it is not recommended to ground the load-bearing structure and antenna to the external air termination network. Grounding should be attached to the protective system of the internal LV (Low Voltage) wiring or grounded internal structures using a CYA 6 mm2 bonding conductor , see Fig. 4.19 Grounding installation 1. 62 RAy3 Microwave Link RACOM s.r.o.

RAy3 Microwave Link 63 Installation 3. If it is not possible to set up conditions of electrical insulation in accordance with article 6.3 of this standard, we recommend connecting the load-bearing structure at roof level to the external air ter-
mination network via an 8mm diameter FeZn conductor and shielding the data cable before entry to the building with a grounding kit and CYA 6 mm2 conductor to the bonding bus, and if not already set up then also to the external air termination network, see Fig. 4.20 Grounding installation 2. 4. If there is not an external LPS on the building we recommend routing lightning current through an 8mm FeZn conductor to a common grounding system, or to a separate grounding electrode with a ground resistance up to 10 . 5. For limiting the overvoltage transferred over the data cable and into the building we recommend fitting surge protection at the interface between zones LPZ 0 and LPZ 1 connected via a CYA 4 mm2 conductor to the same grounding point as the antenna or the antenna mast. 6. We recommend protecting the PoE power supply from overvoltage on the LV side with suitable class D surge protection. RACOM supplies surge protection for installation on Ethernet cables entering buildings. For more details see Surge protection15. Additional safety recommendations Only qualified personnel with authorisation to work at heights are entitled to install antennas on masts, roofs and walls of buildings. Do not install the antenna in the vicinity of electrical wiring. The antenna and bracket should not come into contact with electrical wiring at any time. The antenna and cables are electrical conductors. During installation electrostatic charges may build up which may lead to injury. During installation or repair work to parts of the antenna lead, bare metal parts must be temporarily grounded. The antenna and antenna cable must be grounded at all times. Do not mount the antenna in windy or rainy conditions or during a storm, or if the area is covered with snow or ice. Do not touch the antenna, antenna brackets or conductors during a storm. 15 http://www.racom.eu/eng/products/microwave-link.html#accessories_ochrana 64 RAy3 Microwave Link RACOM s.r.o.

Fig. 4.26: Example of a correct lead installation. 4.6. Power supply RAy microwave unit can be powered by active PoE, passive PoE or by DC power source. All variants of power are supplied through RJ45 Ethernet connector (in slot ETH1+POE). Detailed description and 66 RAy3 Microwave Link RACOM s.r.o. technical parameters of the connector is described in Section 1.3.1, Ethernet 1, PoE - RJ45 connector
( ETH1+POE ). Installation Fig. 4.27: Power supply possibilities RACOM is offering all kinds of power supplies, all guaranteed for compatibility with RAy unit and tested for long-term stability they are listed in Section 2.1, Overview and described in detail in Section 2.2, Details . 4.6.1. PoE power sourcing Active PoE plus (called also Standard PoE+) power supply compatible with IEEE 802.3at, sourced by AC or DC power. The standard IEEE 802.3at defines negotiation method, wires to be used, oper-
ating voltage (36-56V), maximum supported current, overcurrent protection and other parameters. Any power supply compatible with IEEE 802.3at standard can be used. Passive PoE power supply (called sometime PoE injector), is an equipment pushing to the pins of Ethernet connector DC power with a polarity and voltage compatible with IEEE 802.3at standard. Thus, supported voltage, distances, grounding and internal RJ45 pins wiring are identical with Standard PoE+ (mentioned above). Typically, the current is sourced from a DC power with adequate parameters (nominal voltage 24-60V, max current at least 1A). The only additional requirement is that non-grounded wire of DC power circuit in the PoE injector has to be secured by a fuse discon-
necting the power circuit in the case of over current (similar like for DC power source connected directly to the RAy unit by a DC connector). Note RAy unit requires the voltage on RJ45 connector (ETH1+POE) to be at least 20 V, for booting 21 V (to prevent booting with discharged 24 V battery). If a longer Ethernet cable than few meters is used, then both voltage and Watts of power supply and PoE injector has to be adequately higher to cover the power loss within the Ethernet cable. Quality Ethernet cable (i.e. shielded one, like CAB-CAT7) with UV protection is recommended for outside use. Quality connectors (like CON-RJ45-CAT7) are recommend to be used on both ends of Ethernet cable to ensure long-term reliability of the connection. Such connectors have better resistance against oxidation and also against scorching contacts due to spikes during power-
on and power-off the unit by plug / unplug Ethernet cable. Anyhow standard Eth cable with standard Eth connectors should work as well. RACOM s.r.o. RAy3 Microwave Link 67 Installation Overvoltage protection unit is recommended to be applied between RAy unit and PoE power supply for details see Section 4.5, Grounding and overvoltage protection (easily visible on Fig. 4.19, Grounding installation 1). 4.6.2. DC power sourcing Direct DC power input for RAy3 unit described in Section 1.3.3, DC power ( using ETH1+POE ) requires the use of OTH-DC/RJ45. Any kind of DC power source with supplied nominal DC voltage in the range 24-60 V and with enough power for the RAy unit plus energy loss on the DC cable. (For RAy3-17 and RAy3-24 the minimum is 25 Watts). RAy unit requires the voltage on RJ45 connector (ETH1+POE) to be at least 20 V, for booting 21 V
(to prevent booting with discharged 24 V battery). If a longer DC cable than few meters is used, then both voltage and Watts of power supply has to be adequately higher to cover the power loss within the DC cable. RAy3 internal DC power circuits accept both polarities and they ensure galvanic separation of power source line from the RAy unit itself. This simplifies the DC power circuits installation. The DC power circuit must be fitted with a fuse to protect against short circuiting (or power supply has to have such a fuse built-in). Note Typically, DC wires have cross-section 1.5 mm2. DC contacts on OTH-DC/RJ45 are designed for this cross-section. OTH-DC/RJ45 occupies ETH1+POE port on RAy3 unit. When used, Ethernet connection to the unit has to be made through ETH2 port. Possible solutions are described in section NOTE at the end of Section 1.3.3, DC power ( using ETH1+POE ). If shielded DC power cable is used, then shield should be grounded by a proper Grounding kit to the mast or directly to the Grounding screw on RAy unit. If the galvanic separated power source is used and the DC power line needs to be grounded
(either positive or negative wire), the connection of one DC line to the ground should be made by a proper Grounding kit to the mast. Possible is also to use a small piece of DC cable to connect the line to be grounded directly to the Grounding screw on RAy unit. For more details see Section 4.5, Grounding and overvoltage protection. 68 RAy3 Microwave Link RACOM s.r.o. Installation 4.7. Start up Connect a power supply to the installed RAy unit. Connect the device to be used for configuration via WiFi or Ethernet cable. Access the configuration menu using browser or Alignment tool. 4.7.1. Noise on the site This is particularly true for installation of links working in free bands, where the user has no secured frequency. Analyze the level of noise in the individual channels using the spectrum analyzer under Tools/Live data/Frequency spectrum analyzer. If necessary adjust the choice of working channel on the basis of the results. While doing so, respect the rule that all units emit a signal in the Upper part of the range and receive it in the Lower part of the range in one location, or vice versa. A transmitter must not be installed in the part of the spectrum where other units function as receivers. 4.7.2. Directing antennas Placing the antennas to the correct antenna alignment is very important to ensure the strongest signal is received:
Fig. 4.28: Correct alignment diagram For first antenna alignment, use a narrow channel, low modulation and high power where possible. ATPC and ACM functions should be switched off (prevents Tx power fluctuations during alignment). Where possible adjust both ends of link simultaneously to speed up the process. Alternate adjustments at both ends of link in small increments both horizontally and vertically to es-
tablish position with strongest signal (highest value of parameter RSS, received signal strength) whilst looking for maximum main signal (see paragraph on main & side lobes). Link parameter RSS (received signal strength) is a key parameter for a proper antenna alignment and later on for a proper link functionality. All the adjustment effort is to maximize this parameter on both sides of the link and to reach pre-calculated RSS value (which is typically calculated before the link is physically established to ensure necessary link transmission parameters could be met). RACOM s.r.o. RAy3 Microwave Link 69 Installation in section 4.7.3. Several available methods to measure RSS are built in to the RAy unit. Those are discussed in detail Connect a PC, tablet, mobile or voltmeter according your preferred RSS measurement method and find the best possible antenna alignment for both sides of the link. Following section Main and side lobes would help you. Main and side lobes Directional antennas have a specific angle within which radio waves can be transmitted or received
(Angle of Tx/Rx). The strongest signal is emitted in a forward direction; the main lobe is a graphical representation of its direction of travel and strength. However, signals are also emitted and received from unwanted directions through side lobes. In receiving antennas this is a highly significant factor contributing to the level of interference in a radio network (See Fig. 4.29 Antenna lobe diagram ). Fig. 4.30 Signal strength graph provides an indication of comparative signal strength from different beams emitted from a directional antenna. B a c k l o b e S i d e l o b e s 0 90 0

Adjust the antenna alternately in the horizontal and vertical axes and monitor the resulting signal strength. Use the calculation of the expected RSS with the precision of several dBm as guidance. Side lobes transmit a signal ca 20 dBm weaker, see the Microwave link Calculation16 . 16 http://www.racom.eu/eng/products/microwave-link.html#calculation RACOM s.r.o. RAy3 Microwave Link 71 Installation The resulting RSS helps distinguish between the states A-A and C-C which appear similar. It also helps in situations where simple search for a maximum doesnt work as shown in the illustration incorrect adjustment. Real radiation diagrams are more complex, especially in that they run differently in horizont-
al and vertical axes. The basic steps for determ-
ining the main radiation lobe however stay valid. For example:

RSS measurement There are 4 tools available to support measurement of the 2 basic parameters for optimum antenna alignment: RSS (Radio Signal Strength) and MSE (Mean Square Error, the inverse to often used value called SNR - Signal to Noise Ratio):
1. Voltmeter indicates local RSS 2. RAy Tools smartphone application indicates RSS, MSE - Local & Peer 3. Antenna Alignment Tool web page indicates RSS, MSE Local & Peer 4. Bar graph on Live Data page inside web management indicates RSS, MSE, BER Local & Peer Before antenna alignment starts it is recommended to find out RSS and MSE values from the link design for the installed link or calculate these values yourself. There are 4 methods available with in-
creasing levels of accuracy:
Module Calculation inside RAy Tools smartphone application Link calculation on RACOM website17 Use Link calculation chapter in Application notes18 Precise link calculation using dedicated tools (e.g. Pathloss) Voltmeter RAy units support traditional antenna alignment using a volt-
meter measurement representing RSS in dBm (only for a local unit). Connect a voltmeter with the range 2V DC via connectors to the operational unit and adjust antennas to the lowest indicated voltage. Voltage is calibrated according to signal strength. E.g.:
RSS -65 dBm corresponds to voltage 0.65 V, RSS -80 dBm corresponds to voltage 0.80 V etc. RAy Tools smartphone application RAy Tools is an application described in detail in Chapter 7.

Radio unit type: L(ower) or U(pper) part of the frequency band. Horizontal or vertical polarization based on the physical installation. Indic-
ates the polarization of the received signal. Local and Peer are indicated separately. The proper position of the cable is sideways down. Notice for RAy3-17 and RAy3-24 links: One side of the link must be installed in vertical polarization and the other in horizontal polarization. Enable asymmetric channel bandwidth. One of the standard channel widths can be selected. This parameter must be set identically in local and remote (local TX bandwidth = peer RX bandwidth and local RX bandwidth = peer TX bandwidth). When units are connected, this is ensured automatically. If asymmetry is not allowed, then TX bandwidth = RX bandwidth on both units. Allows to choose if TX and RX channel frequencies are selected from the list of predefined channels or if manual input of frequencies would be possible (if supported). TX and RX channels are selected from a list of channels. The basic con-
figuration has the TX and RX options interconnected. In this case the basic duplex spacing between channels is preserved and by selecting one channel, the other three are defined as well. For units operating in free bands, it is possible to disconnect the TX-RX lock and select TX and RX channels individually. Corresponding channels at peer unit are set auto-
matically. NOTE: Non-standard duplex setting leads to non-effective use of the spectrum. Information about duplex spacing of TX and RX channel. Setting of minimum and maximum modulation level for ACM on TX channel
(can be set differently for local and peer unit). ACM is always enabled on RAy3 and would operate within those boundaries. You can select in range from QPSK_S (highest sensitivity for difficult conditions) up to 4096QAM
(highest speed for good conditions). NOTE: On some channel widths the highest available modulation to select may be lower than 4096QAM. Enable automatic control of RF power. Once enabled, the TX power is regulated towards lower level while main-
taining signal level high enough not to affect current degree of modulation. The ATPC algorithm controls the output power according to RSS of the peer unit. The lowest allowed RSS (the threshold) is approx. 10 dBm above declared sensitivity for BER 10-6. If necessary, it is possible to use this parameter to move the threshold slightly up or down. RF output power. With ATPC enabled this parameter defines maximum RF power level. Gain of used antenna. It is used to calculate approximate EIRP. Valid only for RAy3-17 and RAy3-24 links. Approximate calculation of EIRP. Number on the right shows the allowed EIRP limit. Sign between numbers gives information on compliance /
noncompliance with allowed EIRP limits. If the EIRP limit field background is RED, the value shown may be used but will exceed the EIRP limit. RACOM s.r.o. RAy3 Microwave Link 85 Configuration This field value will only be shown for certain RAy3-17 and RAy3-24 links and based on the Frequency tables used. The principle behind ATPC is to maintain the lowest transmitting power without affecting the throughput of the link. The output is primarily controlled by RSS on the opposite side. ATPC is also used to maintain MSE thus protecting the selected modulation level. The ATPC Control loop is evaluated once per second. The principle behind ACM is to maintain the connection between the two units even when degraded propagation conditions are experienced which make it impossible to maintain the selected modulation level. ACM regulates TX modulation across all ranges from ACM min TX modulation up to ACM max TX modulation (as configured by the user) according to the limits in table ACM switching according to MSE state. ACM control loop is evaluated with each frame, i.e. roughly after tens of microseconds. In normal operating conditions, ATPC is applied first (even if it is the slower control loop). When deteri-
oration in propagation conditions gradually increases the attenuation on the route, it is compensated by increasing RF power. ACM control will only be applied in conditions when ATPC reaches its ceiling. 86 RAy3 Microwave Link RACOM s.r.o. 5.4.3. Service access Services Access routes for link configuration.

WiFi is forced to be permanently active (and to transmit SSID) and WiFi management alarm is activated. WiFi passphrase should be set by admin before using this option. This parameter has a higher priority than "WiFi adapter enable on Air link loss", so if it is set ON then WiFi activity does not depend on Air-Link status. Enables DHCP on WiFi adapter if present (for automatic setting of client(s) IP address). Name of service WiFi visible by clients (can be max 32 characters long). Service WiFi encryption is WPA2 and can not be changed. Factory default is "none" due to missing passphrase. WPA2 is applied automatically once any passphrase is entered. Service WiFi passphrase has to be 8-64 characters long. The WiFi pass-
phrase should be set by admin before any use of WiFi. Until passphrase is set, WiFi management alarm is activated. Service WiFi mode can be IEEE 802.11n or IEEE 802.11g WiFi channel can be set 1-11 depending on WiFi mode setting (see para-

Name of each port on the switch (up to 15 characters). Enables functionality of individual port on the switch. Each port can be enabled or disabled. WARNING: When the port is disabled, no communication is possible through this port. Auto negotiation Enables Auto-Negotiation functionality of individual port. Negotiation is an Ethernet procedure by which two connected devices choose common transmission paramet-
ers, such as speed, duplex mode and flow control. In this process, the connected devices first share their capabilities regarding these parameters and then choose the highest performance transmission mode they both support. The device supports three types of Auto-Negotiation:
10/100/1000BASE-T Copper Auto-Negotiation. (IEEE 802.3 Clauses 28 and 40) 1000BASE-X Fiber Auto-Negotiation (IEEE 802.3 Clause 37) SGMII Auto-Negotiation (Cisco specification) 104 RAy3 Microwave Link RACOM s.r.o. Configuration Auto-Negotiation provides a mechanism for transferring information from the local unit to the link partner to establish speed, duplex and Master/Slave preference during a link session. Auto-Negotiation is initiated upon any of the following conditions:
Power up reset Hardware reset Software reset Restart Auto-Negotiation Transition from power down to power up The link goes down The 10/100/1000BASE-T Auto-Negotiation is based on Clause 28 and 40 of the IEEE 802.3 specification. It is used to negotiate speed, duplex and flow control over CAT5 (or higher) UTP cable. Once Auto-Negotiation is initiated, the device determines whether or not the remote device has Auto-Negotiation capability. If so, the device and the remote device negotiate the speed and duplex with which to operate. If the remote device does not have Auto-Negotiation capability, the device uses the parallel detect function to determine the speed of the remote device for 100BASE-TX and 10BASE-T modes. If a link is established based on the parallel detect function, it is then required to establish the link at half-duplex mode only. Refer to IEEE 802.3 clauses 28 and 40 for a full description of Auto-Negotiation. 1000BASE-X Auto-Negotiation is defined in Clause 37 of the IEEE 802.3 specific-
ation. It is used to auto-negotiate duplex and flow control over fibre cable. If one side of the link enables 1000BASE-X Auto-Negotiation and the link partner does not, the link cannot linkup. The device implements an Auto-Negotiation bypass mode. SGMII Auto-Negotiation. SGMII is a de-facto standard designed by Cisco. SGMII uses 1000BASE-X coding to send data as well as Auto-Negotiation information. However, the contents of the SGMII Auto-Negotiation are different than the 1000BASE-X Auto-Negotiation. WARNING: If one device provides Auto-negotiation and the other works with a manual link parameters setting (i.e. without Auto-negotiation) the link operates in half-duplex mode. If the manual setting is set to full-duplex, the "Out collisions"
may occur. Speed / duplex Ethernet link speed and duplex mode can be selected. Both parameters can be either auto negotiated or set manually. When the Auto negotiation parameter is disabled, only manual setting of the speed and duplex is possible. In most cases it is better to enable the auto negotiation and use "auto / auto" speed and duplex settings. There are two possibilities to force the link to operate in specific speed and duplex:
Auto negotiation enabled. Select the desired Speed / duplex. The auto negoti-
ation process advertises only this specified link mode. The link partner is asked to use it. Auto negotiation disabled. Select the desired Speed / duplex. The link is set to this specified link mode. The link partner has to be set manually to the same mode. RACOM s.r.o. RAy3 Microwave Link 105 Configuration Frame mode Ethernet Frame mode control defines the expected Ingress and the generated Egress tagging frame format for this port as follows:
normal DSA provider ether type DSA Normal Network mode uses industry standard IEEE 802.ac Tagged or Untagged frames. Tagged frames use an Ether Type of 0x8100. Ports that are expected to be connected to standard Ethernet devices should use this mode. Inactive options are not required. Provider mode uses user definable Ether Types per port (see Ether type parameter) to define that a frame is Provider Tagged. Ports that are connected to standard Provider network devices, or devices that use Tagged frames with an Ether Type other than 0x8100 should use this mode. Frames that ingress this port with an Ether Type that matches the port's "Ether Type" parameter will be considered tagged, will have the tag's VID and PRI bits assigned to the frame (i.e. they will be used for switching and mapping), and will have the Provider Tag removed from the frame. If subsequent Provider Tags are found following the 1st Provider Tag, they too will be removed from the frame with their VID and PRI bits being ignored. Modified frames will be padded if required. Frames that ingress this port with an Ether Type that does not match the "Ether Type" parameter will be considered untagged. The ingressing frames are modified so they are ready to egress out Customer ports (Normal Network Frame Mode ports) unmodi-
fied. Frames that egress this port will always have a tag added (even if they were already tagged). The added tag will contain this port's
"Ether Type" as its Ether Type. The PRI bits will be the Frame Priority assigned to the frame during ingress. The VID bits will be the source port's Default VID bits (if the source port was in Normal Network mode), or the VID assigned to the frame during ingress
(if the source port was in Provider mode). Valid only for the "p5 CPU" port. Ether Type DSA mode uses standard Marvell DSA Tagged frame information following a user definable Ether Type (see Ether type parameter). This mode allows the mixture of Normal Network frames with DSA Tagged frames and is useful on ports that connect to a CPU. Frames that ingress this port with an Ether Type that matches the port's "Ether Type" will be considered DSA Tagged and processed accordingly. The frame's Ether Type and DSA pad bytes will be removed so the resulting frame will be ready to egress out Marvell DSA Tag Mode ports unmodified. Frames that ingress this port with a different Ether Type will be considered Normal Network Frames and processed accordingly. 106 RAy3 Microwave Link RACOM s.r.o. Ether type MTU [B]
TX / RX flow control Configuration Marvell DSA Tag control frames that egress this port will always get the port's "Ether Type" inserted followed by two pad bytes of 0x00 before the DSA Tag. Marvell DSA Tag Forward frames that egress this port can egress just like the control frames (with the added Ether Type and pad) or they can egress as if the port was configured in Normal Network mode. This selection is controlled by the port's Egress Mode bits above. Ethernet frame type (often called EtherType) is used to indicate which protocol is encapsulated in the payload of an Ethernet Frame. This parameter is important when one protocol is encapsulated to another protocol. Examples:
Eth. type 0x8100 Standard IEEE 802.1q Comment Double-tagged, Q-in-Q or C-tag stacking on C-tag. C-
tag in IEEE 802.1ad frames. S-Tag S-Tag (backbone S-Tag) It is used very often. For example an old non-standard 802.1QinQ protocol uses this value. 0x88a8 0x88e7 0x9100 IEEE 802.1ad IEEE 802.1ah

See http://en.wikipedia.org/wiki/EtherType for further details. Defines maximum transmission unit (MTU) frame size allowed to be received or transmitted from or to a given physical port. This implies that a Jumbo frame may be allowed to be received from a given input port but may or may not be allowed to be transmitted out of a port or ports. The possible values are 1522, 2048 and 10240 Bytes. NOTE: The definition of frame size is counting the frame bytes from MAC_DA through Layer2 CRC of the frame. Defines method of Flow control for each port separately for data transmission (TX) and data receive (RX). It is the mechanism for temporarily stopping the transmission of data on an Ethernet network. Enabling flow control allows use of buffers of connected active network elements for leveling uneven flow of user data. For correct operation it is necessary to also enable Flow control on the connected device. Flow control is handled by sending Pause frames to the connected device. Possible values:
off on auto Flow control is disabled. Flow control is enabled (forced to be active). Sending pause packets is advertised and depends on result on the auto-negotiation process. Auto-Negotiation has to be supported and enabled on the port to take effect. Pause limit in
[frame]
Value limits the number of continuous Pause refresh frames that can be received on this port (if full-duplex) or the number of 16 consecutive collisions (if half-duplex). When a port has flow control enabled, this parameter can be used to limit how long this port can be Paused or Back Pressured off to prevent a port stall through jamming. The Flow Control on the port is (temporarily) disabled when the Pause refresh frames count exceeds the value of this parameter. RACOM s.r.o. RAy3 Microwave Link 107 Configuration Pause limit out
[frame]
Ignore check-
sum Setting this parameter to 0 will allow continuous jamming to be received on this port. Value limits the number of continuous Pause refresh frames that can be transmitted from this port assuming each Pause refresh is for the maximum pause time of 65536 slot times. When full-duplex Flow Control is enabled on this port, this para-
meter is used to limit the number of Pause refresh frames that can be generated from this port to keep this ports link partner from sending any data. Clearing this parameter to 0 will allow continuous Pause frame refreshes to egress this port as long as this port remains congested. Setting this parameter to 1 will allow 1 Pause frame to egress from this port for each congestion situation. Setting this parameter to 2 will allow up to 2 Pause frames to egress from this port for each congestion situation, etc. Enables ignoring Frame checksum (FCS) - or in other words - Force good FCS in the frame. When this parameter is not set (default behaviour), frames entering this port must have a good CRC or else they are discarded. When this parameter is set, the last four bytes of frames received on this port are overwritten with a good CRC and the frames are accepted by the switch (assuming that the frames length is good and it has a destination). 108 RAy3 Microwave Link RACOM s.r.o. Configuration 5.5.3. Advanced RSTP setup Configuring RSTP (Rapid Spanning Tree Protocol by IEEE 802.1w). RSTP provides significantly faster recovery in response to network changes or failures, introducing new convergence behaviors and bridge port roles to do this. RSTP was designed to be backwards-compatible with standard STP. For more information about RSTP, STP, related Path cost, etc. see https://en.wikipedia.org/wiki/Spanning_Tree_Protocol. Fig. 5.20: Menu Switch settings / Advanced / RSTP setup RSTP enable Enables RSTP protocol. When RSTP is enabled, the bridge is created and RSTP service is initiated. Should the unit be connected via two Ethernet cables (using Eth1 and Eth2 ports), the active participation of the RSTP protocol may be neces-
sary. If the parameter is not enabled, the unit transfers the BPDU frames transpar-
ently. DSA"
NOTE: To enable proper RSTP functionality, these switch parameters has to be set:
Switch settings / Interface / Port advanced / Frame mode / p5 CPU: "ether type Switch settings / Interface / Port advanced / Ether type / p5 CPU: "0xDADA"
Switch settings / Advanced / ATU settings / Reserved multicast to CPU: "Enable"
The priority value is a number between 0 and 61440 in incremental steps of 4096, with a default value of 32768. Lower priority values are 'better'. The bridge with the lowest priority value will be elected 'root bridge'. The hello time is the time between each Bridge Protocol Data Unit (BPDU) that is sent on a port. Hello time is equal to 2 seconds by default. The max age timer controls the maximum length of time that passes before a bridge port saves its configuration BPDU information. This time is set to 20 sec by default. Bridge priority Hello time [s]

Algorithm Port name Port priority Path cost Edge MAC address The forward delay is the time that is spent in the listening and learning state. This time is equal to 15 sec by default. This parameter sets the bridge's spanning tree algorithm to operate in normal
(RSTP) or force it to operate in slow (STP) mode. In normal mode, RSTP reverts back to STP on ports where it sees other hosts operating in STP mode. Identification of the internal switch port. The switch ports are connected to an ex-
ternal port or to an internal device (radio modem, management CPU). Eth1 Eth2 CPU Air port1 port10 port0 port9 The external port (with RJ45 interface) labeled "ETH1+POE". The external port (with SFP interface) labeled "ETH2". The internal port to management CPU. The internal port to radio modem, i.e. link to the peer unit. The ports' priority value is a number between 0 and 240 in increments of 16, with a default value of 128. The Path cost indicates "suitability of the link for the data transmission" and it is used in networks with redundant connections to choose the best route for packets. The Path cost can be set automatically or manually. Entering the value of zero sets this parameter automatically. The automatic setup is based on link speed. It is calculated as 20 Tbits/sec divided by a link capacity. For manual settings, lower value increase probability the link is chosen as a primary one for the data transmission. Selecting the checkbox sets the port as an "edge" port. If a port is an edge port it is assumed to be a leaf link in the graph, not connected to any other bridges. Re-
ceiving any STP BPDU's on a port configured as an edge port temporarily overrides edge port behaviour for the port. The ports' default MAC addresses are the same as the MAC address of the unit. Value can be overwritten by a user. 110 RAy3 Microwave Link RACOM s.r.o. 5.6. Tools 5.6.1. Maintenance Backup Configuration Fig. 5.21: Menu Tools / Maintenance / Backup Settings

After 3 minutes, this message appears:
Firmware upgrade started. Estimated time to finish is 370 s. Connection is terminated. After a few minutes, log in to RAy again 6.3.3. Remote unit authorization The RAy unit in default configuration, establishes a connection with any remote unit and both units act as a communication pair. Should the higher protection from the unauthorized communication take-over be required, it is possible to use the so called Secured mode of remote unit authorization. This mode is based on locking the two specific units into one communication pair. Units with Secured mode activated 138 RAy3 Microwave Link RACOM s.r.o. refuse to make a connection with any other communication unit. The units are locked using the unique authorization keys. The keys are exchanged between the units concerned. The authorization keys can be backed up to an external medium to be able to make a service unit exchange, if necessary. Should the Link authorization quard be disabled, the user data occurs even the remote unit is not authorized. Command Line Interface The Secured mode set up process consists of a few steps:
Unique authorization keys generation:
cli_link_key_gen -t b Authorization keys exchange between the two communication units:
cli_link_key_swap Authorization keys activation:
cli_link_key_apply -t b Parameter -t determines whether we configure the whole link (-t b) or only one unit (-t l). Secured mode activation. Both sides of the link must have identically secured mode set On or Off:
cli_cnf_set -t b SVC_SECURE_PEER_MODE=on PEER_SVC_SECURE_PEER_MODE=on Secured mode de-activation:
cli_cnf_set -t b SVC_SECURE_PEER_MODE=off PEER_SVC_SECURE_PEER_MODE=off Backup of the keys to an external medium. The backup has to be performed to be able to make service exchange of the corrupted unit, if necessary. The new exchanged unit is not able to make an active connection with the other unit if it is not loaded with the proper authorization key. cli_link_key_save -s s -f <file>
The key is backed up to a selected file in the internal unit file system. It can be transferred to an ex-
ternal medium using for example the scp client. Authorization key restoration from the external medium. The key has to be transferred to the unit internal file system first. The scp client can be used. The CLI commands can be applied subsequently:
cli_link_key_load -t b -f <file>
cli_link_key_apply -t b 6.3.4. Radio loopback
"Radio loopback" function (accessible via CLI only) provides indicative measurement of XPD (cross polar discrimination). XPD is the ratio between desired signals on preferred polarization and signals on opposite polarization. Command cli_rloop The Radio loopback command takes 10 seconds. The result is suppression [dB] of the unwanted signal
(transmitter to receiver penetration). Radio loopback can only be used with units operating in 17 GHz or 24 GHz band. WARNING: User traffic is interrupted during command execution!

Troubleshooting Polarization incorrect Units RAy3-17 and RAy3-24 must be mounted with opposite polarization; one with TX horizontal polarization (horizontal arrow) and the second with TX vertical polarization (vertical arrow). See Cross polarization for more info. Install the unit with the correct horizontal or vertical polarization: The arrow mark indicates the unit TX polarization. When the arrows heading perpendicular to the earth, the unit transmits a signal in vertical polarization. When the arrow is heading parallel to the earth, the unit transmits a signal in horizontal polarization. The connectors must point downward at an angle. The link cannot be established Double check the correct polarization (see above) of both units on the link. Start with the most resilient configuration. This configuration depends on the type of unit. We re-
commend using the narrowest available bandwidth (e.g. 3.5 MHz), the lowest modulation level
(QPSK_S) and maximum available output power. TX and RX channels must be the same as the RX and TX channels in the remote unit. When the connection has been established and the antennas have been directed, proceed with operation parameters. Access to the Local unit is blocked Access to the Local unit may be accidentally blocked, for instance by disabling HTTPS access. If you can access the Remote unit over HTTPS, type its address in your web browser's address field. The link will transfer the packet over the Local unit with blocked service access all the way to the Remote unit, which will give you access to the control menus of both units. Warning, the Remote unit will report as Local. Distinguishing Local-Remote A unit accessed via service access always reports as Local. If you connect through another (peer) unit and radio channel, a certain amount of caution is necessary. For example, do not reduce the transmission power so that the link interrupts accidentally. Errors of this type should be fixed by the rollback function within approx. 1 minute. Resolution can be done by comparing the length of ping on Local and Remote. Pinging the unit behind the radio channel is slower. The difference is more pronounced in the case of a long packet and the low speed of the radio channel. Access security For better protection against unauthorised access to configuration you should only allow as few kinds of access as possible. The most secure type is SSH with key leave only SSH active with "only key"
choice. RSS To configure the link and monitor its state, several menus display the RSS signal strength. Please keep in mind, that Ray is not a measuring instrument, hence the precision of the RSS reading is limited. Though, in most situations the RSS reading accuracy is better than 2dB, the absolute RSS value should not be used for accurate comparisons e.g. between two links. RACOM s.r.o. RAy3 Microwave Link 143 Troubleshooting Problem with HTTPS certificate See the Appendix C, HTTPS certificate Overexcited receiver A natural property of each radio receiver is to compress the signal in one of the functional blocks, when the signal level gets out of the AGC (automatic gain control) dynamic range. The result of this effect is non-linear distortion of the received signal which is observed as decrease in the signal to noise ratio, i.e. in case of digital modulations increase of the Mean Square Error (MSE). Limit for guaranteed functionality of RAy3 radio receiver is -15 dBm (measured on the waveguide input). This limit applies for all channel bandwidths and all modulations. Beyond this limit the distortion of linearity appears and signal quality is depreciated. In extreme cases, this can lead to the disintegration of the radio link due to reduced signal to noise ratio (as a result of signal distortion). 144 RAy3 Microwave Link RACOM s.r.o.
