For safety and to achieve a good installation, please read and follow these safety precautions:
Cisco Aironet 1550 Series Outdoor Mesh Access Point Hardware Installation Guide 2-6 OL-24247-01 Chapter 2 Installing the Access Point Avoiding Damage to Radios in a Testing Environment
Select your installation site with safety, as well as performance in mind. Remember: electric power lines and phone lines look alike. For safety, assume that any overhead line can kill.
Call your electric power company. Tell them your plans, and ask them to come look at your proposed installation.
Plan your installation carefully and completely before you begin. Successful raising of a mast or tower is largely a matter of coordination. Each person should be assigned to a specific task and should know what to do and when to do it. One person should be in charge of the operation to issue instructions and watch for signs of trouble.
When installing the access point and antennas, remember:
Do not use a metal ladder. Do not work on a wet or windy day. Do dress properlyshoes with rubber soles and heels, rubber gloves, long sleeved shirt or jacket.
Use a rope to lift the access point. If the assembly starts to drop, get away from it and let it fall.
If any part of the antenna system should come in contact with a power line, do not touch it or try to remove it yourself. Call your local power company. They will remove it safely. If an accident should occur, call for qualified emergency help immediately. Avoiding Damage to Radios in a Testing Environment The radios on outdoor units (bridges) have higher transmit power levels than radios on indoor units
(access points). When you test high-power radios in a link, you must avoid exceeding the maximum receive input level for the receiver. At levels above the normal operating range, packet error rate (PER) performance is degraded. At even higher levels, the receiver can be permanently damaged. To avoid receiver damage and PER degradation, you can use one of the following techniques:
Separate the omnidirectional antennas by at least 2 ft (0.6 m) to avoid receiver damage or by at least 25 ft (7.6 m) to avoid PER degradation. Note These distances assume free space path loss and are conservative estimates. Required separation distances for damage and performance degradation levels in actual deployments are less if conditions are not non-line-of-sight.
Reduce the configured transmit power to the minimum level.
Use directional antennas, and keep them away from each other.
Cable the radios together using a combination of attenuators, combiners, or splitters to achieve a total attenuation of at least 60 dB. For a radiated test bed, the following equation describes the relationships among transmit power, antenna gain, attenuation, and receiver sensitivity:
txpwr + tx gain + rx gain - [attenuation due to antenna spacing] < max rx input level Where:
txpwr = Radio transmit power level tx gain = transmitter antenna gain rx gain = receiver antenna gain OL-24247-01 Cisco Aironet 1550 Series Outdoor Mesh Access Point Hardware Installation Guide 2-7 Installation Guidelines Chapter 2 Installing the Access Point For a conducted test bed, the following equation describes the relationships among transmit power, antenna gain, and receiver sensitivity:
txpwr - [attenuation due to coaxial components] < max rx input level Caution Under no circumstances should you connect the antenna port from one access point to the antenna port of another access point without using an RF attenuator. If you connect antenna ports, you must not exceed the maximum survivable receive level of 0 dBm. Never exceed 0 dBm, or damage to the access point can occur. Using attenuators, combiners, and splitters having a total of at least 60 dB of attenuation ensures that the receiver is not damaged and that PER performance is not degraded. Installation Guidelines Because the access point is a radio device, it is susceptible to common causes of interference that can reduce throughput and range. Follow these basic guidelines to ensure the best possible performance:
For information on planning and initially configuring your Cisco Mesh network, refer to the Cisco Wireless Mesh Access Points, Design and Deployment Guide, Release 7.0.
Review the FCC guidelines for installing and operating outdoor wireless LAN devices at http://www.cisco.com/en/US/partner/prod/collateral/routers/ps272/data_sheet_c78-647116_ps114 51_Products_Data_Sheet.html.
Perform a site survey before beginning the installation.
Install the access point in an area where structures, trees, or hills do not obstruct radio signals to and from the access point.
The access points can be installed at any height, but best throughput is achieved when all the access points are mounted at the same height. We recommend installing the access points no higher than 40 feet to allow support for wireless clients on the ground. Note To calculate path loss and to determine how far apart to install access points, consult an RF planning expert. Site Surveys Every network application is a unique installation. Before installing multiple access points, you should perform a site survey to determine the optimum use of networking components and to maximize range, coverage, and network performance. Consider the following operating and environmental conditions when performing a site survey:
Data ratesSensitivity and range are inversely proportional to data bit rates. The maximum radio range is achieved at the lowest workable data rate. A decrease in receiver sensitivity occurs as the radio data increases.
Antenna type and placementProper antenna configuration is a critical factor in maximizing radio range. As a general rule, range increases in proportion to antenna height. However, do not place the antenna higher than necessary, because the extra height also increases potential interference from other unlicensed radio systems and decreases the wireless coverage from the ground.
Physical environmentClear or open areas provide better radio range than closed or filled areas. Cisco Aironet 1550 Series Outdoor Mesh Access Point Hardware Installation Guide 2-8 OL-24247-01 Chapter 2 Installing the Access Point Installation Guidelines
ObstructionsPhysical obstructions such as buildings, trees, or hills can hinder performance of wireless devices. Avoid locating the devices in a location where there is an obstruction between the sending and receiving antennas. Before Beginning the Installation Before you begin the installation process:
Ensure that a site survey has been performed.
Ensure that your network infrastructure devices are operational and properly configured.
Ensure that your controllers are connected to switch trunk ports.
Ensure that your switch is configured with untagged access ports for connecting your access points.
Ensure that a DHCP server with Option 43 configured is reachable by your access points, or manually configure the controller information in the access point (for additional information, refer to the Configuring DHCP Option 43 section on page F-1).
Become familiar with the access point installation components (see the Becoming Familiar with Access Point Installation Components section on page 2-9). Becoming Familiar with Access Point Installation Components The access point is designed to be installed in an outdoor environment, such as the exterior roof overhang of a tall building or a streetlight pole. Carefully review the following figures to become familiar with the system components, connectors, indicators, cables, system interconnection, and grounding:
Components in a typical access point installation (see Figure 2-1)
Pole mount installation (see Figure 2-2)
Cable strand mount installation (see Figure 2-3
Streetlight power tap installation (see Figure 2-4) Note The illustrations in this document show all available connections for the access point. Unused connections are capped with a connector plug to ensure the watertight integrity of the access point. liquid-tight adapters are provided for connector openings, which can be installed before or after deploying the access point.

User supplied. 2. The safety ground wire in the AC power cord must have a ground path to a grounding rod. 3. The shielded Ethernet cable has a ground path through the power injector and the safety ground wire in the AC power cord. Note The 1552 access point was designed with consideration for resistance to effects of lightning effects on the access point electronics. The 1552 access point employs lightning arrestor circuitry on the Ethernet and power ports. On the input Ethernet port, Gas Discharge Tubes (GDT) are used for the Power Entry Module (PEM) to mitigate lightning effect. On the AC power, GDTs are also used along with fuses to mitigate high-current condition. For the DC power, a fuse is used to mitigate high current condition. While not a common practice, the user may want to consider using lightning protection at the antenna ports for added protection. To meet EN/IEC60950-22 (Clause 4.2) requirements, the installer must ensure that additional protection is provided external to this equipment to reduce transient surges from Overvoltage IV to Overvoltage Category II at the AC power input of the access point. The over-voltage and fault-current protection components used to achieve this protection must comply with the IEC 61643 Cisco Aironet 1550 Series Outdoor Mesh Access Point Hardware Installation Guide 2-10 OL-24247-01 Chapter 2 Installing the Access Point Installation Guidelines series of standards. To meet CAN/CSA-C22.2 No. 60950-22-07/UL60950-22 requirements, the installer may use alternative components to provide this additional protection. Those components may comply with ANSI/IEEE C62.11, CSA Certification Notice No. 516, CSA C22.2 No. 1, or UL 1449. Suitability of the components for the application must be determined for the intended installation. (For example, some devices are suitable for installation on the load side of the service entrance only, and some are suitable for use with cord-connected equipment only.) Warning Installation of the equipment must comply with local and national electrical codes. Statement 1074 Figure 2-2 Pole Mount Installation 1 1 2 3 5 1 2 Stainless steel mounting straps

MAC address filtering is enabled by default. This enables the controller to respond to the listed access points. To add a MAC filter entry on the controller, follow these steps:
Step 1 Step 2 Step 3 Log into your controller using a web browser. Choose SECURITY > MAC Filtering > New. Enter the MAC address of the access point to the MAC Filter list; for example, 00:0B:91:21:3A:C7. Note The access point MAC address is located on the bottom of the unit. When two MAC addresses are shown, use the top MAC address. Step 4 Select a WLAN ID or Any WLAN from the WLAN ID pop-up menu. OL-24247-01 Cisco Aironet 1550 Series Outdoor Mesh Access Point Hardware Installation Guide 2-13 Installation Guidelines Step 5 Step 6 Step 7 Step 8 Chapter 2 Installing the Access Point Enter a description (32 characters maximum) of the access point in the Description field; for example, Fisher_Street_00.0B.91.21.3A.C7 shows the location and MAC address of the access point. Choose an interface from the Interface Name pop-up menu, and click Apply. Repeat Steps 2 to 6 to add other access points to the list. Log out of your controller, and close your web browser. Configuring a RAP The access point defaults to the mesh access point (MAP) radio role. One or more of your access points must be reconfigured as a root access point (RAP). The RAPs connect to a wired Ethernet link through a switch to the controller. The MAPs use their wireless backhaul interface to connect to a RAP to reach the controller. To configure a RAP on the controller GUI, follow these steps:
Step 1 Step 2 Step 3 Step 4 Step 5 Step 6 Step 7 Log into your controller using a web browser. Click Wireless. When your access point associates to the controller, the name of the access point appears in the AP Name list. Double-click your access point name. Find Mesh Information, and choose Root AP by clicking the drop-down arrow in the AP Role field. Click Apply. Repeat Steps 2 through 5 for each RAP. Log out from your controller, and close your web browser. Configuring a Bridge Group Name The bridge group name (BGN) controls the association of the access points to a RAP. BGNs can be used to logically group the radios to avoid different networks on the same channel from communicating with each other. This setting is also useful if you have more than one RAP in your network in the same area. If you have two RAPs in your network in the same area (for more capacity), we recommend that you configure the two RAPs with the same BGN, but on different channels. The BGN is a string of ten characters maximum. A factory-set bridge group name (NULL VALUE) is assigned during manufacturing. It is not visible to you, but allows new access point radios to join a network of new access points. The BGN can be reconfigured from the Controller CLI and GUI. After configuring the BGN, the access point reboots. The BGN should be configured very carefully on a live network. You should always start from the farthest node (last node) from the RAP and move towards the RAP. If you start configuring the BGN in a different location, then the access points beyond this point (farther away) are dropped, as they have a different BGN. Cisco Aironet 1550 Series Outdoor Mesh Access Point Hardware Installation Guide 2-14 OL-24247-01 Chapter 2 Installing the Access Point Installing the Access Point To configure the BGN for the access points using the GUI, follow these steps:
Log into your controller using a web browser. Click Wireless. When access points associates to the controller, the name of the access point appears in the AP Name list. Double-click on an access point name. Find Mesh Information, and enter the new BGN in the Bridge Group Name field. Click Apply. Repeat Steps 2 through 5 for each access point. Log out from your controller, and close your web browser. Step 1 Step 2 Step 3 Step 4 Step 5 Step 6 Step 7 Installing the Access Point This section provides instructions for installing your access points. Personnel installing the access point must understand wireless access points and bridging techniques and grounding methods. Caution All installation methods for mounting an access point on any wall surface is subject to the acceptance of local jurisdiction. Installation Options There are two optional installation kits:
Pole mount kitUsed for pole, wall, or streetlight installations
Strand mount kitUsed for cable strand installations Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030 Warning Installation of the equipment must comply with local and national electrical codes. Statement 1074 Caution To provide inline PoE, you must use the power injector (AIR- PWRINJ1500-2=) specified for the access point. Other power injectors, PoE switches, and 802.3af power sources do not provide adequate power, which might cause the access point to malfunction and cause over-current conditions at the power source. You must ensure that the switch port connected to the access point has PoE turned off.

Cisco Aironet 1550 Series Outdoor Mesh Access Point Hardware Installation Guide 2-20 OL-24247-01 Chapter 2 Installing the Access Point Pole Mounting Installing the Access Point The access point can be installed where power is available, without the need for a wired LAN connection. The access point uses intelligent wireless routing that is based on the Adaptive Wireless Path Protocol
(AWPP). AWPP enables a remote access point to dynamically optimize the best route to the wired LAN network using another access point. The 1522 access point uses the 5-GHz radio for the Mesh backhaul and connections. The 2.4-GHz radio is used for local wireless client access. To mount your access point on a vertical pole or streetlight pole, you need to install two metal bands around the pole to support the access point. This process requires extra tools and material not provided in the pole mount kit (see Table 2-2).

Statement 1080 Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046 Removing the Access Point from Service When removing an access point from service, make sure you remove power from the access point before opening the cover and disconnecting the AC input wiring. When removing the AC wiring, the ground connection should be the last to be disconnected. Conducting Periodic Inspections The access point should be inspected periodically to ensure normal and airtight operation in the hazardous location environment. Table 2-5 lists the inspection routines and their periodicity. Table 2-5 Periodic Inspection Table Inspection Routine Inspect O-ring seals and exterior electrical connections for aging, corrosion, and low ground resistance. Inspect cover and liquid-tight adapter gaskets for airtightness. Periodicity Every 3 years Every 5 years What to Do Next When you power up a MAP that is not connected to a wired Ethernet, fiber-optic, or cable network to the controller, the access point uses the Cisco Adaptive Wireless Path Protocol (AWPP) to bind to another mesh access point (MAP) with the best path to a root access point (RAP) connected to the wired network to a controller. The access point sends a discovery request when powered up. If you have configured the access point in the controller correctly, the controller sends back a discovery response to the access point. When that happens, the access point sends out a join request to the controller, and the controller responds with a join confirmation response. Then the access point establishes a Control And Provisioning of Wireless Access Points (CAPWAP) connection to the controller and gets the shared secret configured on the controller. Refer to the Cisco Wireless LAN Controller Configuration Guide for more information on configuring, monitoring, and operating your access points.

Statement 1040 4 2 Introduction to the Access Point The Cisco Aironet 1550 Series Outdoor Mesh Access Point (hereafter called the access point or AP) is a ruggedized outdoor access designed for service in mesh networks. The 1550 series leverages 802.11n technology with integrated radio and internal/external antennas. The 1550 outdoor platform consists of Multiple Input Multiple Output (MIMO) WLAN radios and with integrated spectrum intelligence
(Clean Air). CleanAir provides full 11n data rates while detecting, locating, classifying and mitigating radio frequency (RF) interference to provide the best client experience possible. CleanAir technology on the outdoor 11n platform mitigates WiFi and non-WiFi interference on 2.4 GHz radios. The 1550 AP series offers multi-band 2.4 GHz, and 5 GHz configurations with an option to configure access and backhaul radios. The 1550 outdoor radios are called 2.4 GHz MIMO radios and 5 GHz MIMO radios. The radios can be configured for one or two radio operation. The 2.4 GHz radios are used primarily for local access and the 5 GHz radios for both local access and wireless backhaul in the Mesh mode. The 1550 series supports the modularity of the 1520 series and allows flexibility in radio configuration. In addition to full interoperability with 802.11n clients, the 1550 series interoperates with legacy clients and offers enhanced backhaul performance. The 1552C access point is configured with an integrated DOCSIS 3.0 cable modem. The access point is a standalone unit that can be cable strand or tower mounted. The access point can also operate as a relay node for other access points not directly connected to a wired network. Intelligent wireless routing is provided by the Adaptive Wireless Path Protocol (AWPP). This enables each access point to identify its neighbors and intelligently choose the optimal path to the wired network by calculating the cost of each path in terms of signal strength and the number of hops required to get to a controller. The access point is configured, monitored, and operated through a Cisco wireless LAN controller (WLC), referred to as a controller in this document. The WLC is described in the appropriate Cisco Wireless LAN Controller Configuration Guide. The Cisco Mesh Networking Solution Deployment Guide describes how to plan and initially configure the Cisco mesh network, which supports wireless point-to-multipoint mesh deployments. The controllers use a browser-based management system, a command-line interface (CLI), or the Cisco Wireless Control System (WCS) network management system to manage the controller and the associated access points. The access point is compliant with Wi-Fi Protected Access 2 (WPA2) and employs hardware-based Advanced Encryption Standard (AES) encryption between wireless nodes to provide end-to-end security. 5 3 Unpacking the Access Point Follow these steps to unpack the access point:

- 5.725 GHz), and the upper ISM band (5.725 - 5.850 GHz). It has two transmitters with a maximum total output power of 26 dBm for UNII-2 and Extended/ETSI bands for the A-domain. The total maximum output power for the upper ISM band is 28 dBm for A-domain. Power settings will change depending on the regulatory domain. Output power is configurable for 5 power levels in 3 dB steps. Its three receivers enables maximum-ratio combining (MRC). The 1552 models C and I access points are equipped with three new integrated dual-band antennas, with 2 dBi gain at 2.4 GHz and 4 dBi gain at 5 GHz. The antenna works in cable strand mount and low cost, low profile applications. 14 External Antenna Option Warning In order to comply with radio frequency (RF) exposure limits, the antennas up to 8 dBi gain for this product should be placed no less than 20cm (8") from your body or nearby persons. This distance shall be increased to 40cm (16") with antennas that have gain between 8 and 14 dBi. Statement 339 Warning Do not locate the antenna near overhead power lines or other electric light or power circuits, or where it can come into contact with such circuits. When installing the antenna, take extreme care not to come into contact with such circuits, because they may cause serious injury or death. For proper installation and grounding of the antenna, please refer to national and local codes (for example, U.S.:NFPA 70, National Electrical Code, Article 810, Canada: Canadian Electrical Code, Section 54). Statement 1052 Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030 The 1552 models E and H access points are equipped with three N-type radio frequency (RF) connectors (antenna ports 4, 5, and 6) on the bottom of the unit for external antennas to support multiple input multiple output (MIMO) operation as shown in Figure 7.

Power transmitted is a combination of the amplification of the signal and the antenna gain. The access point has been designed to operate with the Cisco provided antennas. 17 Integrated Antenna Option The 1552C and 1552I models use the Integrated Low Profile Dual-Band 2.4/5 GHz Dipole Antenna Array. The antenna contains an array of three dual-band dipole antennas. The three dipole antennas are contained within this single radome, thereby greatly reducing the antennas visual footprint, and greatly reducing the possibility of snagging the antenna on the cable bundle, the RF cable, or test cables. The antennas operate over both 2.4 GHz and 5.25 5.85 GHz bands. Each of the three dipole antennas is a dual-band antenna, covering both the 2.4 2.483 GHz band, and the 5.25 5.85 GHz bands. The antenna have a peak gain of about 2 dBi at 2.4 GHz and 4 dBi at 5 GHz. The antenna unit is gray weatherproof radome for outdoor operation. The low profile integrated antennas are attached to the bottom of a Cisco access point. The 1552C comes with the option of a C-bracket for strand mounting. The 1552C mesh access point chassis mounting brackets and low profile antenna all fit within the 30 cm vertical right-of-way for cable strand-mounted equipment. The antennas are internally connected to the diplexer ports of the outdoor mesh access point 2.4/5 GHz 2x3 MIMO radios. Figure 9 shows an installed integrated low-profile dual-band (2.4 GHz and 5.25 GHz) 3-element array antenna.

Statement 1074 Warning This equipment must be externally grounded using a customer-supplied ground wire before power is applied. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Statement 366 Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. Statement 1001 The 1550 series access point supports the following power sources:
AC power90 to 480 VAC, 47 to 63 Hz
Streetlight power tap
Quazi-AC power-over-cable (POC)40 to 90 VAC, 47 to 63 Hz, quasi-square wave
External 12 VDC power
Power-over-Ethernet power injector (same as 1520)
Internal 6 ampere-hour battery backup Caution Do not place the power injector in an unprotected outdoor environment because water could get into the power injector and cause a short circuit and possible fire. Warning Connect the unit only to DC power source that complies with the Safety Extra-Low Voltage (SELV) requirements in IEC 60950 based safety standards Statement 1033 20 The 1550 series access point can be connected to more than one power source. The access point detects available input sources and switches to the preferred power source using the following prioritization:
AC or POC power
External DC power
Power injector PoE power (same as 1520)
Internal battery power Warning This unit might have more than one power supply connection. All connections must be removed to de-energize the unit. Statement 1028 Warning To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord. Statement 1023 Caution To provide inline PoE, you must use the 1500 power injector (AIR-PWRINJ1500-2=). Other power injectors, PoE switches, and 802.3af power sources cannot provide adequate power, which may cause the access point to malfunction and cause over-current conditions at the power source. You must ensure that the switch port connected to the access point has PoE turned off. Caution Do not install the power injector and the power outdoors. They must be installed indoors. Caution When the access point is installed outdoors or in a wet or damp location, the AC branch circuit that is powering the access point should be provided with ground fault protection
(GFCI), as required by Article 210 of the National Electrical Code (NEC). Three AC power cord options are available:
40-ft (12.2-m) power cord for installations in the US and Canada. One end of the power cord is terminated with an access point AC power connector and the other end is terminated with an AC plug (AIR-CORD-R3P-40NA=).
40-ft (12.2-m) power cord for use outside the US and Canada. One end of the power cord is terminated with an access point AC power connector and the other end is unterminated.
(AIR-CORD-R3P-40UE=). 21
4-ft (1.2-m) streetlight power tap adapter for light pole installations in the US and Canada
(AIR-PWR-ST-LT-R3P=). Ethernet (PoE) Ports The access point supports an Ethernet uplink port (PoE-In) and a PoE out port (PoE-Out). The access point Ethernet uplink port uses an RJ-45 connector (with weatherproofing) to link the access point to the 10BASE-T, 100BASE-T, or 1000BASE-T network. The Ethernet cable is used to send and receive Ethernet data and to optionally supply inline 56-VDC power from the power injector. The minimum length of this cable must be not less than 10 feet (3 meters). The access point PoE-Out Ethernet port uses an RJ-45 connector (with weatherproofing) to provide LAN connectivity and IEEE 802.3af power to a peripheral customer device, such as a camera or sensor gateway. The Ethernet MAC addresses are printed on a label on the bottom of the access point under the LEDs. Tip The access point senses the Ethernet and power signals and automatically switches internal circuitry to match the cable connections. Caution To provide inline PoE, you must use the 1550 series power injector. Other power injectors, PoE switches, and 802.3af power sources can not provide adequate power, which may cause the access point to malfunction and cause possible over-current conditions at the power source. Cable Option The factory-orderable cable option provides a cable modem and Power-over-Cable (POC) capabilities for the access point for high-speed data transfer and Internet access. When the cable option is selected and installed, the access point uses its F-type cable connector to receive both data and power. Data is passed between wireless clients on the mesh network to the cable company network via the internal cable modem of the access point. In this configuration, the access point receives operating power from the cable. For detailed installation information, see the Cisco Aironet 1550 Series Outdoor Access Point Hardware Installation Guide. Configuration information can be found in the controller configuration guide of the controller you are using. 22 Fiber Option Warning Class 1 laser product. Statement 1008 The factory-orderable fiber option provides a fiber input and output capability. Fiber data is transmitted and received over a single-strand fiber cable, which is connected to the access point using these small-factor pluggable (SFP) modules:
100BASE-BX10-U fiber Rugged SFP module
1000BASELX single-mode Rugged SFP module
1000BASESX multimode Rugged SFP module Note SFP modules are not hot-swappable. One fiber connection is available on both the 1552E and 1552H access points. The fiber connection is on the bottom of both the 1552E and 1552H access points (shown on Figure 1). Client data is passed to the network controller through the fiber connection via a fiber capable switch. For detailed installation information about the fiber option, see the Cisco Aironet 1550 Series Outdoor Mesh Access Point Hardware Installation Guide. Configuration information can be found in the controller configuration guide of the controller you are using. 6 Network Deployment Examples The access point is a wireless device designed for wireless client access and point-to-point bridging, point-to-multipoint bridging, and point-to-multipoint mesh wireless connectivity. The access point provides 5-GHz backhaul capability to link with another access point to reach a wired network connection or to provide repeater operations for other access points. The access point plays two primary radio roles: a root access point (hereafter called a RAP) or a mesh
(non-root) access point (hereafter called a MAP), which is the default role of all access points. When the access point has a fiber or wired Ethernet or cable connector connection to the controller (through a switch), the radio role is called a RAP. In order to be considered a RAP, the access point must be configured as a RAP. A RAP is a parent node to any bridging or mesh network. A controller can support one or more RAPs, each one parenting the same or different wireless networks. There can be more than one RAP for the same mesh network for redundancy. RAPs and MAPs can support wireless clients on the 2.4-GHz and 5-GHz band. Client access on 5-GHz is called universal client access. 23 When the access point does not have a wired Ethernet connection to the controller (through a switch), the radio role is called a MAP. The MAPs have a wireless connection (through the backhaul interface) to other MAPs and finally to a RAP which has an Ethernet connection through a switch to the controller. MAPs may also have a wired Ethernet connection to a local LAN and serve as a bridge endpoint for that LAN (using a point-to-point or point-to-multipoint bridge connection). Wireless Backhaul The access point supports wireless backhaul capability using the 5-GHz radio to bridge to another access point to reach a wired network connection to a controller as shown in Figure 10. The access point connected to the wired network is considered a RAP in this configuration. The remote access point is considered a MAP and transfers wireless client traffic to the RAP for transfer to the wired network. Control And Provisioning of Wireless Access Points (CAPWAP) control traffic is also transferred over this bridged link. Figure 10 Access Point Backhaul Example
(5.8 Ghz)
(2.4 Ghz) 8 3 4 8 4 1 Point-to-Point Bridging The access points can be used to extend a remote network by using the 5-GHz backhaul radio to bridge the two network segments as shown in Figure 11. To support Ethernet bridging, you must enable bridging on the controller for each access point. By default this capability is turned-off for all access points. Wireless client access is supported; however, if bridging between tall buildings, the 2.4-GHz wireless coverage area may be limited and possibly not suitable for direct wireless client access. 24 Figure 11 Access Point Point-to-Point Bridging Example
(5 GHz) 5 9 4 5 5 2 Point-to-Multipoint Bridging The access points can be used as a RAP to connect multiple remote MAPs with their associated wired networks. By default this capability is turned-off for all access points. To support Ethernet bridging, you must enable bridging on the controller for each access point. Wireless client access can be provided over the bridging link; however, if bridging between tall buildings, the 2.4-GHz wireless coverage area may be limited and possibly not suitable for direct wireless client access. Figure 12 illustrates an example of access point-to-multipoint bridging. Figure 12 Access Point Point-to-Multipoint Bridging Example
(5 GHz)
(5 GHz) 4 9 4 5 5 2 25 Point-to-Multipoint Mesh Network The access point is typically deployed in a mesh network configuration. In a typical mesh deployment, one or more RAPs have a wired network connection through a switch to a controller. Other remote MAPs without wired network connections use the backhaul feature to optimally link to a RAP that is connected to the wired network. In the mesh network, the links between the access points are referred to as the backhaul links. Intelligent wireless routing is provided by the Adaptive Wireless Path protocol (AWPP). This enables each MAP to identify its neighbors and intelligently choose the optimal path to the RAP with the wired network connection by calculating the cost of each path in terms of signal strength and the number of hops required to get to a controller with signal strength given priority since signal strength determines the data rate available for backhaul. Figure 13 illustrates a typical mesh configuration using access points.

Access points and controllers in Layer 3 configurations use IP addresses and UDP packets, which can be routed through large networks. Layer 3 operation is scalable and is the recommended operation. Figure 14 illustrates a typical Layer-3 wireless network configuration containing access points and a controller. Figure 14 Typical Layer 3 Access Point Network Configuration Example 8 5 4 8 4 1 7 Preparing the Access Point The access point is a radio device which is susceptible to common causes of interference that can reduce throughput and range. Follow these basic guidelines to ensure the best possible performance:
For information on planning and initially configuring your Cisco mesh network, refer to the Cisco Wireless Mesh Access Points, Design and Deployment Guide, Release 7.0. These documents are available on cisco.com.
Do not install the access point in an area where structures, trees, or hills obstruct radio signals to and from the access point.
You can install the access point at any height, but best throughput is achieved when the access points are mounted at the same height. Note To perform path loss calculation and to determine how far apart to install access points, consult an RF planning expert. 27 Site Surveys Cisco recommends that you perform a site survey before installing the equipment. A site survey reveals problems that can be resolved before the network is operational. Because 802.11a/b/g/n operates in an unlicensed spectrum, there may be sources of interference from other 802.11a wireless devices
(especially in multi-tenant buildings) that could degrade your 802.11 signals. A site survey can determine if such interference exists at the time of deployment. A proper site survey involves temporarily setting up mesh links and taking measurements to determine whether your antenna calculations are accurate. Determine the correct locations and antenna types before you drill holes and route cables and mounting equipment. Tip When power is not readily available during a site survey, use an unrestricted power supply
(UPS) to temporarily power the mesh link. Consider the following operating and environmental conditions when performing a site survey:
How far is your wireless link?
Has a previous site survey been conducted?
Do you have a clear Fresnel zone between the access points or radio line of sight?
What is the minimum acceptable data rate within the link?
Do you have the correct antenna (if more than one antenna is being offered)?
Do you have access to both of the mesh site locations?
Do you have the proper permits, if required?
Are you following the proper safety procedures and practices?
Have you configured the access points before you go onsite? It is always easier to resolve configurations or device problems first.
Do you have the proper tools and equipment to complete your survey?
Avoiding Damage to Radios in a Testing Environment The radios on outdoor units (bridges) have higher transmit power levels than radios on indoor units
(access points). When you test radios in a link, you must avoid exceeding the maximum receive input level of the receiver. At levels higher than the normal the operating range and packet error rate (PER) performance of the receiver is degraded. At even higher levels, the receiver can be permanently damaged. 28 To avoid receiver damage and PER degradation, you can use one of the following techniques:
Separate the omnidirectional antennas by at least 2 ft (0.6 m) to avoid receiver damage or by at least 25 ft (7.6 m) to avoid PER degradation.
Reduce the configured transmit power to the minimum level.
Cable the radios together using a combination of attenuators, combiners, or splitters to achieve a total attenuation of at least 60 dB. For a radiated test bed, the following equation describes the relationships among transmit power, antenna gain, attenuation, and receiver sensitivity:
txpwr + tx antenna gain + rx ant gain - [attenuation due to antenna spacing] < max rx input level Where:
txpwr = Radio transmit power level tx gain = transmitter antenna gain rx gain = receiver antenna gain For a conducted test bed, the following equation describes the relationships among transmit power, antenna gain, and receiver sensitivity:
txpwr - [attenuation due to coaxial RF Attenuator components] < max rx input level
(0 dbm) Caution Under no circumstances should you connect the antenna port from one access point to the antenna port of another access point without using an RF attenuator. If you connect antenna ports you must not exceed the maximum survivable receive level of 0 dBm. Never exceed 0 dBm or damage to the access point can occur. Using attenuators, combiners, and splitters having a total of at least 60 dB of attenuation ensures that the receiver is not damaged and PER performance is not degraded. 29 Before You Begin Warning Read the installation instructions before connecting the system to the power source. Statement 1004 Before you begin the installation process:
Become familiar with the procedures for mounting the access point.
Become familiar with the access point connections (Figure 1 on page 10, Figure 2 on page 11, and Figure 6 on page 14).
Verify that the switch you are using to connect the controller is configured properly. Note For additional installation, mounting and safety information for the outdoor mesh access point, see the Cisco Aironet 1550 Series Outdoor Mesh Access Point Hardware Installation Guide, which is available on Cisco.com, and Safety Warnings for Cisco Aironet 1520 Series Outdoor Mesh Access Points, which accompanies this guide. 8 Deploying the Access Point Warning Do not operate the unit near unshielded blasting caps or in an explosive environment unless the device has been modified to be especially qualified for such use. Statement 364 The access point is deployed on Layer 3 networks. Layer 3 is the default mode for a newly configured wireless LAN controller. This guide assumes that you will be deploying your access point on a Layer 3 network and a DHCP server is available. Before deploying the access point, make sure the controller to which the access point will associate is properly configured by performing the following operations:
Make sure that the wireless LAN controller is set to Layer 3 mode
Verify the wireless LAN controller software version
Record the access point BVI MAC address
Enter the access point BVI MAC address to the wireless LAN controller filter list Verifying the Wireless LAN Controller Mode Follow these steps to verify that the wireless LAN controller mode is set to Layer 3:
30 Step 1 Open your web-browser and enter the IP address of your wireless LAN controller. Be sure to Step 2 precede the IP address with https://. A login screen appears. Enter your username and password. The default case-sensitive username and password are admin and admin. The Summary page appears. From the top menu bar, click CONTROLLER. The Controller General page appears. Step 3 Step 4 Verify that the CAPWAP Transport Mode is set to Layer 3. If it is not, change it to Layer 3 and click Apply. Save any changes you made. From the menu bar, click MONITOR to return to the Monitor Summary page. Step 5 Step 6 Verifying the Wireless LAN Controller Software Version On the Summary page, you can verify the software version that the wireless LAN controller is running. If a version update is necessary, refer to the appropriate controller configuration documentation. Recording the Access Point MAC Address Use a text file to record the MAC address of all the access points you intend to deploy in your network. Having a file of access point MAC addresses will be of considerable value for future testing. While you are compiling the list, you might want to change the name of the access point to something you can easily remember. The name can contain up to 32 characters. The following example, fisher_street:ea:co contains the last four HEX characters of the access point MAC address. Adding the Access Point MAC Address to the Wireless LAN Controller Filter List The wireless LAN controller maintains an access point authorization MAC address list and responds to discovery requests from access points on that list. To add the access point MAC address (or MAC addresses) to the Wireless LAN controller filter list, follow these steps:
Step 1 If you are not logged onto the wireless LAN controller, log on now. The Summary page appears. Step 2 On the menu bar, click SECURITY. The Security RADIUS Authentication Server page appears. Step 3 Under AAA in the left frame, click MAC Filtering. The Security MAC Filtering page appears. Step 4 Click New. The MAC Filters New page appears. 31 Step 5 Enter the MAC address of the access point in the MAC Address field. You can also use the config macfilter add command to add a MAC filter entry to the controller. Select a WLAN ID or Any WLAN from the WLAN ID pop-up menu. Enter a description (32 characters maximum) of the access point in the Description field. Step 6 Step 7 Step 8 Choose an interface from the Interface Name pop-up menu. Step 9 Click Apply. Step 10 Repeat this process to add other access points to the list. Note You can also use the controller CLI command config macfilter add to add a MAC filter entry on the controller. Step 11 On the menu bar, click Monitor to return to the Monitor Summary page. Verifying Controller Association To verify that your access point is associated to the wireless LAN controller, perform these steps:
Log into your controller web interface (https) using a web browser. Step 1 Step 2 Click Wireless and verify that your access point MAC address is listed under Ethernet MAC. Step 3 Log out of the controller and close your web browser. Deployment Notes Using a DHCP Server in a Layer 3 Mesh Network To use a DHCP server in a Layer 3 mesh network, make sure the wireless LAN controller is in Layer 3 mode. You must also configure DHCP option 43 on the DHCP server. After the controller is restarted, the access point receives IP addresses from the DHCP server. 32 Configuring DHCP Option 43 You can use DHCP Option 43 to provide a list of controller IP addresses to the access points, enabling each access point to find and join a controller. This section contains a DHCP Option 43 configuration example on a Microsoft Windows 2003 Enterprise DHCP server for use with Cisco Aironet lightweight access points. Additional information about Microsoft DHCP Option 43 is available on Cisco.com at the following URL:
http://www.cisco.com/en/US/tech/tk722/tk809/technologies_configuration_example09186a0080871 4fe.shtml DHCP Option 43 server implementation information for Cisco IOS is available at cisco.com at the following URL:
http://www.cisco.com/en/US/docs/wireless/technology/controller/deployment/guide/dep.html#wp106 8287 Note In DHCP Option 43, you should use the IP address of the controller management interface. Note DHCP Option 43 is limited to one access point type per DHCP pool. You must configure a separate DHCP pool for each access point type. Cisco Aironet 1000 and 1500 (1505 and 1510) series access points use a comma-separated string format for DHCP Option 43. Other Cisco Aironet access points use the type-length-value (TLV) format for DHCP Option 43. DHCP servers must be programmed to return the option based on the DHCP Vendor Class Identifier (VCI) string (DHCP Option 60) of the access point. The VCI strings for Cisco access points capable of operating in lightweight mode are listed in Table 1:

Step 1 Enter configuration mode at the Cisco IOS CLI. Step 2 Create the DHCP pool, including the necessary parameters such as default router and name server. The commands used to create a DHCP pool are as follows:
ip dhcp pool pool name network IP Network Netmask default-router Default router dns-server DNS Server Where:
pool name is the name of the DHCP pool, such as AP1000. IP Network is the network IP address where the controller resides, such as 10.0.15.1 Netmask is the subnet mask, such as 255.255.255.0 Default router is the IP address of the default router, such as 10.0.0.1 DNS Server is the IP address of the DNS server, such as 10.0.10.2 34 Step 3 Add the Option 60 line using the following syntax:
option 60 ascii VCI string For the VCI string, use the value from Table 1. The quotation marks must be included. Step 4 Add the option 43 line using the following syntax:
option 43 ascii Comma Separated IP Address List For example, if you are configuring Option 43 for Cisco 1000, 1500, or 1550 series access points using the controller IP addresses 10.126.126.2 and 10.127.127.2, add the following line to the DHCP pool in the Cisco IOS CLI:
option 43 ascii 10.126.126.2,10.127.127.2 The quotation marks must be included. Configuring Option 43 for Cisco 1100, 1130, 1200, 1240, 1250, 1300, 1520, and 1550 Series Access Points To configure DHCP Option 43 for Cisco 1100, 1130, 1200, 1240, 1250, 1300, 1520, and 1550 series access points in the embedded Cisco IOS DHCP server, follow these steps:
Step 1 Enter configuration mode at the Cisco IOS CLI. Step 2 Create the DHCP pool, including the necessary parameters such as default router and name server. The commands used to create a DHCP pool are as follows:
ip dhcp pool pool name network IP Network Netmask default-router Default router dns-server DNS Server Where:

This section provides troubleshooting procedures for basic problems with the access point. For the most up-to-date, detailed troubleshooting information, refer to the Cisco Support website at cisco.com. 49 Guidelines for Using the Access Point You should keep these guidelines in mind when you use the access point:
The access points can only communicate with controllers and cannot operate independently in standalone mode.
The access point communicates only with controllers and does not support Wireless Domain Services (WDS). The access points cannot communicate with WDS devices. However, the controller provides functionality equivalent to WDS when an access point associates to it.
The access point supports Layer 3 CAPWAP communications with the controllers. In Layer 3 operation, the access point and the controller can be on the same or different subnets. The access point communicates with the controller using standard IP packets. Layer 3 operation is scalable and is recommended by Cisco. Unless it has a static IP address, a Layer 3 access point on a different subnet than the controller requires a DHCP server on the access point subnet and a route to the controller. The route to the controller must have destination UDP ports 12222 and 12223 open for CAPWAP communications. The routes to the primary, secondary, and tertiary controllers must allow IP packet fragments.
Before deploying your mesh access points ensure that the following has been done:
Your controllers are connected to switch ports that are configured as trunk ports. Your mesh access points are connected to switch ports that are configured as untagged access ports. A DHCP server is reachable by your mesh access points and has been configured with Option 43. Option 43 is used to provide the IP addresses of the Management Interfaces of your controllers. Typically, a DHCP server can be configured on a Cisco Layer 3 switch or router. Optionally a DNS server can be configured to enable a local domain Cisco CAPWAP controller (CISCO-CAPWAP-CONTROLLER.<local domain>) to resolve to the IP address of the Management Interface of your controller. Your controllers are configured and reachable by the mesh access points. Your controllers are configured with the MAC addresses of the mesh access points. 50 Checking the LEDs Four LEDs, located between the PoE-In and PoE-Out connectors, monitor the status of the access point power, uplinks, and radios. Figure 16 identifies and describes the LED functions. Table 2 provides additional LED signal information.

If all LEDs off, the access point has no power. 1. 2. When the access point power supply is initially turned on, all LEDs are amber. Note Regarding LED status colors, it is expected that there will be small variations in color intensity and hue from unit to unit. This is within the normal range of the LED manufacturers specifications and is not a defect. See the Cisco Aironet 1550 Series Outdoor Mesh Access Point Hardware Installation Guide for a detailed description of the LEDs and additional troubleshooting tips. 52 Misconfigured Access Point IP address IP address misconfiguration can occur when you are re-addressing a segment of your mesh network and you start at the mesh access point connected to the wired network (RAP). To avoid this problem, always start the IP addressing changes from the farthest access point and work your way back to the root access point. This problem might also happen if you move equipment such as uninstalling an mesh access point and then redeploying with a different IP subnet in another physical location on the mesh network. Another option to fix this misconfigured IP address is to physically take a controller in Layer 3 mode with a root access point to the location of the misconfigured mesh access point. Set the bridge group name for the root access point to match the misconfigured access point. Add the access point MAC address to the filter list of the controller. When the misconfigured access point appears in the Summary page of the controller, configure the access point with an IP address. If you are using a static IP address on the access point and plan on redeploying the access point on another subnet, perform a clear config command from the controller for that access point while it is joined before you remove it from the network. Verifying the Controller MAC Filter List Prior to activating your access point, you must ensure that the access point MAC address has been added to the controller MAC Filter list and that Mac Filter List is enabled. To view the MAC addresses added to the controller MAC filter list and ensure the MAC filter list is enabled, you can use the controller CLI or the controller GUI. Controller CLI Use the show macfilter summary controller CLI command to view the MAC addresses added to the controller filter list. Controller GUI Log into your controller web interface (HTTPS) using a web browser and click SECURITY > AAA >
MAC Filtering to view the MAC addresses added to the controller filter list. Then click Wireless >
Mesh to ensure the MAC filter list is enabled. 53 11 Cisco 90-Day Limited Hardware Warranty Terms There are special terms applicable to your hardware warranty and various services that you can use during the warranty period.

Statement 1040 2 Introduction to the Access Point The Cisco Aironet 1550 Series Outdoor Mesh Access Point (hereafter called the access point) is a ruggedized outdoor access designed for service in mesh networks. The 1550 series leverages 802.11n technology with integrated radio and external antennas. The 1550 outdoor platform consists of
(Multiple Input Multiple Output) MIMO WLAN radios and optional integrated spectrum intelligence
(Clean Air). CleanAir provides full 11n data rates while detecting, locating, classifying and mitigating radio frequency (RF) interference to provide the best client experience possible. CleanAir technology on the outdoor 11n platform mitigates WiFi and non-WiFi interference for both the access and backhaul radios. 4 DRAFT The 1550 AP series offers multi-band 2.4 GHz, and 5 GHz configurations with an option to configure access and backhaul radios. The 1550 outdoor radios are called 2.4GHz MIMO radios and 5GHz MIMO radios. The radios can be configured for one or two radio operation. The 2.4GHz radios are used primarily for local access and the 5 GHz radios for wireless backhaul in the Mesh. The 1550 series supports the modularity of the 1520 series and allows flexibility in radio configuration. In addition to full interoperability with 802.11n clients, the 1550 series interoperates with legacy clients and offers enhanced backhaul performance. The 1550 series can also be configured with an integrated DOCSIS 3.0 cable modem. Note The 4.9-GHz Public Safety band requires a license and may be used only by qualified Public Safety operators as defined in section 90.20 of the FCC rules. The access point is a standalone unit that can be cable strand or tower mounted. The access point can also operate as a relay node for other access points not directly connected to a wired network. Intelligent wireless routing is provided by the patent-pending Adaptive Wireless Path Protocol
(AWPP). This enables each access point to identify its neighbors and intelligently choose the optimal path to the wired network by calculating the cost of each path in terms of signal strength and the number of hops required to get to a controller. The access point is configured, monitored, and operated through a Cisco wireless LAN controller (hereafter called a controller) as described in the appropriate Cisco Wireless LAN Controller Configuration Guide. The Cisco Mesh Networking Solution Deployment Guide describes how to plan and initially configure the Cisco mesh network, which supports wireless point-to-point, point-to-multipoint, and mesh deployments. The controllers use a browser-based management system, a command-line interface (CLI), or the Cisco Wireless Control System (WCS) network management system to manage the controller and the associated access points. The access point is compliant with Wi-Fi Protected Access 2 (WPA2) and employs hardware-based Advanced Encryption Standard (AES) encryption between wireless nodes to provide end-to-end security. 3 Unpacking the Access Point Note When you are unpacking the access point, do not remove the foam blocks attached to the antenna connectors.

The 2GHz b/g/n radio operates in 2.4 GHz ISM band. It supports channels 1-11 in US, 1-13 in Europe, and 1-13 in Japan. It has two transmitters with a maximum total output power of 25dBm for 802.11b/g/n operation. Output power is configurable to 5 levels. It has three receivers that enable maximum-ratio combining (MRC). 11 DRAFT The 5GHz a/n radio operates in the UNII-2 band (5.25 - 5.35 GHz), UNII-2 Extended/ETSI band (5.47
- 5.725 GHz), and the upper ISM band (5.725 - 5.850 GHz). It has two transmitters with a maximum total output power of 26 dBm for UNII-2 and Extended/ETSI bands. The total maximum output power for the upper ISM band is 28 dBm. Output power is configurable for 5 power levels in 3dB steps. Its three receivers enables maximum-ratio combining (MRC). The 1550 access point antenna options include a new integrated dual-band omni-directional antenna, with 2dBi gain at 2.4-2.5 GHz and 4 dBi gain at 5.25-5.85GHz. The antenna works in cable strand mount and low cost, low profile applications. External Antennas Warning In order to comply with radio frequency (RF) exposure limits, the antennas for this product should be positioned no less than 20cm from your body or nearby persons. Statement 339 Warning Do not locate the antenna near overhead power lines or other electric light or power circuits, or where it can come into contact with such circuits. When installing the antenna, take extreme care not to come into contact with such circuits, because they may cause serious injury or death. For proper installation and grounding of the antenna, please refer to national and local codes (for example, U.S.:NFPA 70, National Electrical Code, Article 810, Canada: Canadian Electrical Code, Section 54). Statement 1052 Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030 The access point is equipped with three N-type radio frequency (RF) connectors (antenna ports 1, 2, and 3) on the top of the unit for external antennas to support multiple input single output (MISO) operation as shown in Figure 1. The access point also has three N-type RF connectors (antenna ports 4, 5, and 6) on the bottom of the unit for external antennas as shown in Figure 2. When using the optional Cisco compact omnidirectional antennas, the 2.4- and 5-GHz antennas connect directly to the access point. The Cisco omnidirectional antennas use vertical polarization. The access point can also be equipped with specific third-party external antennas (see Table 1), subject to local regulatory requirements. If you install third-party antennas, be sure to install them with all waterproofing steps recommended by the third-party manufacturer. For additional information, see the documentation shipped with the antenna. 12 DRAFT Note The FCC limits the amount of power this device can transmit. Power transmitted is a combination of the amplification of the signal and the antenna gain. The access point has been designed to operate with the antennas listed below having a maximum gain of 4 dBi for 2.5-GHz and 7 dBi for 5-GHz antennas. Antennas not included in this list or having a higher gain are strictly prohibited for use with the access point. The required antenna impedance is 50 ohms. Note To reduce potential radio interference to other users, the antenna type and its gain should be chosen so that the equivalent subtropical radiated power (EIRP) is not more than required for successful communication. Antenna Configurations Two antenna configurations are available, based on how the access point is mounted. The cable strand mounting configuration uses three antennas and the tower mount configuration uses four antennas. Table 1 identifies the antenna ports used and explains the configurations.

Internal battery power Warning This unit might have more than one power supply connection. All connections must be removed to de-energize the unit. Statement 1028 18 DRAFT Warning To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord. Statement 1023 Caution To provide inline PoE, you must use the 1520 series power injector. Other power injectors, PoE switches, and 802.3af power sources cannot provide adequate power, which may cause the access point to malfunction and cause over-current conditions at the power source. You must ensure that the switch port connected to the access point has PoE turned off. Caution Do not install the power injector and the power outdoors. They must be installed indoors. Caution When the access point is installed outdoors or in a wet or damp location, the AC branch circuit that is powering the access point should be provided with ground fault protection
(GFCI), as required by Article 210 of the National Electrical Code (NEC). Three AC power cord options are available:
40-ft (12.2-m) power cord for light pole installations in the US and Canada. One end of the power cord is terminated with an access point AC power connector and the other end is terminated with an AC plug (AIR-CORD-R3P-50NA=).
40-ft (12.2-m) power cord for use outside the US and Canada. One end of the power cord is terminated with an access point AC power connector and the other end is unterminated.
(AIR-CORD-R3P-50UE=).
4-ft (1.2-m) streetlight power tap adapter for light pole installations in the US and Canada
(AIR-PWR-ST-LT-R3P=). Ethernet (PoE) Ports The access point supports an Ethernet uplink port (POE-In) and a downlink port (POE-Out). The access points Ethernet uplink port uses an RJ-45 connector (with weatherproofing) to link the access point to the 10BASE-T, 100BASE-T, or 1000BASE-T network. The Ethernet cable is used to send and receive Ethernet data and to optionally supply inline 56-VDC power from the power injector. The minimum length of this cable must be not less than 10 feet (3 meters). 19 DRAFT The access points downlink Ethernet port uses an RJ-45 connector (with weatherproofing) to provide LAN connectivity and IEEE 802.3af power to a peripheral customer device, such as a camera or sensor gateway. The BVI MAC addresses are printed on the label on the side of the access point Tip The access point senses the Ethernet and power signals and automatically switches internal circuitry to match the cable connections. Caution To provide inline PoE, you must use the 1520 series power injector. Other power injectors, PoE switches, and 802.3af power sources can not provide adequate power, which may cause the access point to malfunction and cause possible over-current conditions at the power source. Cable Option The factory-orderable cable option provides a cable modem and Power-over-Cable capabilities for the access point for high-speed data transfer and Internet access. When the cable option is installed, the access point uses its F-type cable connection to receive both data and power. Data is passed between wireless clients on the mesh network to the cable companys network via the access points internal cable modem. In this configuration, the access point receives operating power from the cable. For detailed installation information, see the Cisco Aironet 1550 Series Outdoor Access Point Hardware Installation Guide. Configuration information can be found in the controller configuration guide of the controller you are using. Fiber Option Warning Class 1 laser product. Statement 1008 The factory-orderable fiber option provides a fiber input and output capability. Fiber is data is transmitted and received over a single-strand fiber cable which is connected to the access point using:
100BASE-BX10-U fiber Rugged small factor pluggable (SFP) module
1000BASELX single-mode Rugged SFP module
1000BaseSX multimode Rugged SFP module Note SFP modules are not hot-swappable. 20 DRAFT For convenience, two fiber connections are available on the access point. One connection is on the bottom of the unit (shown on Figure 1) and the other on the left side (shown on Figure 2). Client data is passed to the network controller through the fiber connection via a fiber capable switch. For detailed installation information about the fiber option, see the Cisco Aironet 1550 Series Outdoor Mesh Access Point Hardware Installation Guide. Configuration information can be found in the controller configuration guide of the controller you are using. 6 Network Deployment Examples The access point is a wireless device designed for wireless client access and point-to-point bridging, point-to-multipoint bridging, and point-to-multipoint mesh wireless connectivity. The access point provides 5-GHz backhaul capability to link with another access point to reach a wired network connection or to provide repeater operations for other access points. The access point plays two primary radio roles: a root access point (hereafter called a RAP) or a non-root access point (hereafter called a MAP), which is the default role of all access points. When the access point has a wired Ethernet or cable connector connection to the controller (through a switch), the radio role is called a RAP. In order to be considered a RAP, the access point must be configured as a RAP. A RAP is a parent node to any bridging or mesh network. A controller can support one or more RAPs, each one parenting the same or different wireless networks. There can be more than one RAP for the same mesh network for redundancy. RAPs and MAPs can support wireless clients on the 2.4-GHz band. When the access point does not have a wired Ethernet connection to the controller (through a switch), the radio role is called a MAP. The MAPs have a wireless connection (through the backhaul interface) to other MAPs and finally to a RAP which has an Ethernet connection through a switch to the controller. MAPs may also have a wired Ethernet connection to a local LAN and serve as a bridge endpoint for that LAN (using a point-to-point or point-to-multipoint bridge connection). Wireless Backhaul The access point supports wireless backhaul capability using the 5-GHz radio to bridge to another access point to reach a wired network connection to a controller as shown in Figure 6. The access point connected to the wired network is considered a RAP in this configuration. The remote access point is considered a MAP and transfers wireless client traffic to the RAP for transfer to the wired network. Lightweight access point protocol (LWAPP) control traffic is also transferred over this bridged link. 21 DRAFT Figure 6 Access Point Backhaul Example
(5.8 Ghz)
(2.4 Ghz) 8 3 4 8 4 1 Point-to-Point Bridging The access points can be used to extend a remote network by using the 5-GHz backhaul radio to bridge the two network segments as shown in Figure 7. To support Ethernet bridging, you must enable bridging on the controller for each access point. Wireless client access is supported; however, if bridging between tall buildings, the 2.4-Ghz wireless coverage area may be limited and possibly not suitable for direct wireless client access. Figure 7 Point-to-Point Bridging Example 0 4 4 8 4 1 Point-to-Multipoint Bridging The access points can be used as a RAP to connect multiple remote MAPs with their associated wired networks. By default this capability is turned-off for all access points. To support Ethernet bridging, you must enable bridging on the controller for each access point. Wireless client access can be provided over the bridging link; however, if bridging between tall buildings, the 2.4-Ghz wireless coverage area may be limited and possibly not suitable for direct wireless client access. 22 DRAFT Figure 8 illustrates an example of access point-to-multipoint bridging. Figure 8 Point-to-Multipoint Bridging Example 9 3 4 8 4 1 Mesh Network The access point is typically deployed in a mesh network configuration. In a typical mesh deployment, one or more RAPs have a wired network connection through a switch to a controller. Other remote MAPs without wired network connections use the backhaul feature to optimally link to a RAP that is connected to the wired network. In the mesh network, the links between the access points are referred to as the backhaul links. Intelligent wireless routing is provided by the patent-pending Adaptive Wireless Path protocol
(AWPP). This enables each MAP to identify its neighbors and intelligently choose the optimal path to the RAP with the wired network connection by calculating the cost of each path in terms of signal strength and the number of hops required to get to a controller with signal strength given priority since signal strength determines the bandwidth available for backhaul. Figure 9 illustrates a typical mesh configuration using MAPs and RAPs. 23 DRAFT Figure 9 Typical Mesh Configuration Using MAPs and RAPs RAP Network WCS MAP 1 MAP 2 MAP 3 MAP 4 MAP 5 MAP 6 MAP 7 MAP 8 MAP 9 1 4 4 8 4 1 Layer 3 Network Operation The access points support Layer 3 network operation. Access points and controllers in Layer 3 configurations use IP addresses and UDP packets, which can be routed through large networks. Layer 3 operation is scalable and recommended by Cisco. Figure 10 illustrates a typical Layer-3 wireless network configuration containing access points and a controller. 24 DRAFT Figure 10 Typical Layer 3 Access Point Network Configuration Example 8 5 4 8 4 1 7 Preparing the Access Point The access point is a radio device which is susceptible to common causes of interference that can reduce throughput and range. Follow these basic guidelines to ensure the best possible performance:
For information on planning and initially configuring your Cisco mesh network, refer to the Cisco Mesh Networking Solution Deployment Guide or the Cisco Aironet 1500 Series Wireless Mesh AP Design Guide. These documents are available on cisco.com.
Do not install the access point in an area where structures, trees, or hills obstruct radio signals to and from the access point.
You can install the access point at any height, but best throughput is achieved when the access points are mounted at the same height. Note To perform path loss calculation and to determine how far apart to install access points, consult an RF planning expert. Site Surveys Cisco recommends that you perform a site survey before installing the equipment. A site survey reveals problems that can be resolved before the network is operational. Because 802.11a is unlicensed, there may be sources of interference from other 802.11a wireless devices (especially in multi-tenant buildings) that could degrade your 802.11 signals. A site survey can determine if such interference exists. A proper site survey involves temporarily setting up mesh links and taking measurements to determine whether your antenna calculations are accurate. Determine the correct locations and antenna types before you drill holes and route cables and mounting equipment. 25 DRAFT Tip When power is not readily available during a site survey, use an unrestricted power supply
(UPS) to temporarily power the mesh link. Consider the following operating and environmental conditions when performing a site survey:
How far is your wireless link?
Has a previous site survey been conducted?
Do you have a clear Fresnel zone between the access points or radio line of sight?
What is the minimum acceptable data rate within the link?
Do you have the correct antenna?
Do you have access to both of the mesh site locations?
Do you have the proper permits, if required?
Do you have a partner? Never attempt to survey or work alone on a roof or tower.
Have you configured the access points before you go onsite? It is always easier to resolve configurations or device problems first.
Do you have the proper tools and equipment to complete your survey?
Avoiding Damage to Radios in a Testing Environment The radios on outdoor units (bridges) have higher transmit power levels than radios on indoor units
(access points). When you test high power radios in a link, you must avoid exceeding the receivers maximum receive input level. At levels higher than the normal the receivers operating range, packet error rate (PER) performance is degraded. At even higher levels, the receiver can be permanently damaged. To avoid receiver damage and PER degradation, you can use one of the following techniques:
Separate the omnidirectional antennas by at least 2 ft (0.6 m) to avoid receiver damage or by at least 25 ft (7.6 m) to avoid PER degradation. Note These distances assume free space path loss and are conservative estimates. Required separation distances for damage and performance degradation levels in actual deployments will be less due to non line-of-sight propagation conditions.
Reduce the configured transmit power to the minimum level.
Use directional antennas and keep them pointed away from each other. 26 DRAFT
Cable the radios together using a combination of attenuators, combiners, or splitters to achieve a total attenuation of at least 60 dB. For a radiated test bed, the following equation describes the relationships among transmit power, antenna gain, attenuation, and receiver sensitivity:
txpwr + tx gain + rx gain - [attenuation due to antenna spacing] < max rx input level Where:
txpwr = Radio transmit power level tx gain = transmitter antenna gain rx gain = receiver antenna gain For a conducted test bed, the following equation describes the relationships among transmit power, antenna gain, and receiver sensitivity:
txpwr - [attenuation due to coaxial components] < max rx input level Caution Under no circumstances should you connect the antenna port from one access point to the antenna port of another access point without using an RF attenuator. If you connect antenna ports you must not exceed the maximum survivable receive level of 0 dBm. Never exceed 0 dBm or damage to the access point can occur. Using attenuators, combiners, and splitters having a total of at least 60 dB of attenuation ensures that the receiver is not damaged and PER performance is not degraded. Before You Begin Warning Read the installation instructions before connecting the system to the power source. Statement 1004 Before you begin the installation process:
Become familiar with the procedures for mounting the access point.
Become familiar with the access point connections (Figure 1 on page 9, Figure 2 on page 10, and Figure 3 on page 11).
Verify that the switch you are using to connect the controller is configured properly. 27 DRAFT Note For additional installation, mounting and safety information for the outdoor mesh access point, see the Cisco Aironet 1550 Series Outdoor Mesh Access Point Hardware Installation Guide, which is available on Cisco.com, and Safety Warnings for Cisco Aironet 1520 Series Outdoor Mesh Access Points, which accompanies this guide. 8 Deploying the Access Point Warning Do not operate the unit near unshielded blasting caps or in an explosive environment unless the device has been modified to be especially qualified for such use. Statement 364 The access point is deployed on Layer 3 networks. Layer 3is the default mode for a newly configured wireless LAN controller. This guide assumes that you will be deploying your access point on a Layer 3 network and a DHCP server is available. Before deploying the access point, make sure the controller to which the access point will associate is properly configured by performing the following operations:
Make sure that the wireless LAN controller is set to Layer 3 mode
Verify the wireless LAN controller software version
Record the access point BVI MAC address
Enter the access point BVI MAC address to the wireless LAN controller filter list Verifying the Wireless LAN Controller Mode Follow these steps to verify that the wireless LAN controller mode is set to Layer 3:
Step 1 Open your web-browser and enter the IP address of your wireless LAN controller. Be sure to Step 2 precede the IP address with https://. A login screen appears. Enter your username and password. The default case-sensitive username and password are admin and admin. The Summary page appears. From the top menu bar, click CONTROLLER. The Controller General page appears. Step 3 Step 4 Verify that the LWAPP Transport Mode is set to Layer 3. If it is not, change it to Layer 3 and click Apply. Save any changes you made. Step 5 28 DRAFT Step 6 From the menu bar, click MONITOR to return to the Monitor Summary page. Verifying the Wireless LAN Controller Software Version On the Summary page, you can verify the software version that the wireless LAN controller is running. If a version update is necessary, refer to the appropriate controller configuration documentation. Recording the Access Point MAC Address Use a text file to record the MAC address of all the access points you intend to deploy in your network. Having a file of access point MAC addresses will be of considerable value for future testing. While you are compiling the list, you might want to change the name of the access point to something you can easily remember. The name can contain up to 32 characters. The following example, fisher_street:ea:co contains the last four HEX characters of the access point MAC address. Adding the Access Point MAC Address to the Wireless LAN Controller Filter List The wireless LAN controller maintains an access point authorization MAC address list and responds to discovery requests from access points on that list. Follow these steps to add the access point MAC address (or MAC addresses) to the Wireless LAN controller filter list:
Step 1 If you are not logged onto the wireless LAN controller, log on now. The Summary page appears. Step 2 On the menu bar, click SECURITY. The Security RADIUS Authentication Server page appears. Step 3 Under AAA in the left frame, click MAC Filtering. The Security MAC Filtering page appears. Step 4 Click New. The MAC Filters New page appears. Step 5 Enter the MAC address of the access point in the MAC Address field. You can also use the config macfilter add command to add a MAC filter entry to the controller. Select a WLAN ID or Any WLAN from the WLAN ID pop-up menu. Enter a description (32 characters maximum) of the access point in the Description field. Step 6 Step 7 Step 8 Choose an interface from the Interface Name pop-up menu. Step 9 Click Apply. Step 10 Repeat this process to add other access points to the list. 29 DRAFT Note You can also use the controller CLI command config macfilter add to add a MAC filter entry on the controller. Step 11 On the menu bar, click Monitor to return to the Monitor Summary page. Verifying Controller Association To verify that your access point is associated to the wireless LAN controller, perform these steps:
Log into your controller web interface (https) using a web browser. Step 1 Step 2 Click Wireless and verify that your access point MAC address is listed under Ethernet MAC. Step 3 Log out of the controller and close your web browser. Deployment Notes Using a DHCP Server in a Layer 3 Mesh Network To use a DHCP server in a Layer 3 mesh network, make sure the wireless LAN controller is in Layer 3 mode. You must also configure DHCP option 43 on the DHCP server. After the controller is restarted, the access point receives IP addresses from the DHCP server. Configuring DHCP Option 43 You can use DHCP Option 43 to provide a list of controller IP addresses to the access points, enabling each access point to find and join a controller. This section contains a DHCP Option 43 configuration example on a Microsoft Windows 2003 Enterprise DHCP server for use with Cisco Aironet lightweight access points. Additional information about Microsoft DHCP Option 43 is available on Cisco.com at the following URL:

30 DRAFT http://www.cisco.com/en/US/docs/wireless/technology/controller/deployment/guide/dep.html#wp106 8287 Note In DHCP Option 43, you should use the IP address of the controller management interface. Note DHCP Option 43 is limited to one access point type per DHCP pool. You must configure a separate DHCP pool for each access point type. Cisco Aironet 1000 and 1500 (1505 and 1510) series access points use a comma-separated string format for DHCP Option 43. Other Cisco Aironet access points use the type-length-value (TLV) format for DHCP Option 43. DHCP servers must be programmed to return the option based on the access points DHCP Vendor Class Identifier (VCI) string (DHCP Option 60). The VCI strings for Cisco access points capable of operating in lightweight mode are listed in Table 3:

This section provides troubleshooting procedures for basic problems with the access point. For the most up-to-date, detailed troubleshooting information, refer to the Cisco Support website at cisco.com. 47 DRAFT Guidelines for Using the Access Point You should keep these guidelines in mind when you use the access point:
The access points can only communicate with controllers and cannot operate independently.
The access point communicates only with controllers and does not support Wireless Domain Services (WDS). The access points cannot communicate with WDS devices. However, the controller provides functionality equivalent to WDS when an access point associates to it.
The access point supports Layer 3 LWAPP communications with the controllers. In Layer 3 operation, the access point and the controller can be on the same or different subnets. The access point communicates with the controller using standard IP packets. Layer 3 operation is scalable and is recommended by Cisco. Unless it has a static IP address, a Layer 3 access point on a different subnet than the controller requires a DHCP server on the access point subnet and a route to the controller. The route to the controller must have destination UDP ports 12222 and 12223 open for LWAPP communications. The routes to the primary, secondary, and tertiary controllers must allow IP packet fragments.
Before deploying your mesh access points ensure that the following has been done:
Your controllers are connected to switch ports that are configured as trunk ports. Your mesh access points are connected to switch ports that are configured as untagged access ports. A DHCP server is reachable by your mesh access points and has been configured with Option 43. Option 43 is used to provide the IP addresses of the Management Interfaces of your controllers. Typically, a DHCP server can be configured on a Cisco Layer 3 switch or router. Optionally a DNS server can be configured to enable a local domain Cisco LWAPP controller
(CISCO-LWAPP-CONTROLLER.<local domain>) to resolve to the IP address of the Management Interface of your controller. Your controllers are configured and reachable by the mesh access points. Your controllers are configured with the MAC addresses of the mesh access points. Checking the LEDs Four LEDs, located between the PoE-In and PoE-Out connectors, monitor the status of the access points power, uplinks, and radios. Figure 12 identifies and describes the LED functions. Table 7 provides additional LED information. 48 DRAFT Figure 12 LEDs 1 Status LED Displays the current status of the access point and power. 3 Radio 1 Status LEDDisplays the status of the 802.11n radio. 2 Uplink Status LEDDisplays the status of all 4 Radio 2 Status LEDDisplays the status of uplink connections (Ethernet, fiber, cable, and mesh). the 802.11n radio.

All LEDs dark indicates no power is applied. Status LED Firmware failure LWAPP discovery Uplink LED All LEDs amber indicates the access point power supply is on. RF-1 and RF-2 LEDs Firmware failure Note Regarding LED status colors, it is expected that there will be small variations in color intensity and hue from unit to unit. This is within the normal range of the LED manufacturers specifications and is not a defect. See the Cisco Aironet 1550 Series Outdoor Mesh Access Point Hardware Installation Guide for a detailed description of the LEDs and additional troubleshooting tips. Misconfigured Access Point IP address IP address misconfiguration can occur when you are re-addressing a segment of your mesh network and you start at the mesh access point connected to the wired network (RAP). To avoid this problem, always start the IP addressing changes from the farthest access point and work your way back to the root access point. This problem might also happen if you move equipment such as uninstalling an mesh access point and then redeploying with a different IP subnet in another physical location on the mesh network. Another option to fix this misconfigured IP address is to physically take a controller in Layer 3 mode with a root access point to the location of the misconfigured mesh access point. Set the bridge group name for the root access point to match the misconfigured access point. Add the access points MAC address to the controllers filter list. When the misconfigured access point appears in the controllers Summary page, configure the access point with an IP address. If you are using a static IP address on the access point and plan on redeploying the access point on another subnet, perform a clear config command from the controller for that access point while it is joined before you remove it from the network. 50 DRAFT Verifying the Controller MAC Filter List Prior to activating your access point, you must ensure that the access point MAC address has been added to the controller MAC Filter list and that Mac Filter List is enabled. To view the MAC addresses added to the controller MAC filter list and ensure the MAC filter list is enabled, you can use the controller CLI or the controller GUI. Controller CLI Use the show macfilter summary controller CLI command to view the MAC addresses added to the controller filter list. Controller GUI Log into your controller web interface (HTTPS) using a web browser and click SECURITY > AAA >
MAC Filtering to view the MAC addresses added to the controller filter list. Then click Wireless >
Mesh to ensure the MAC filter list is enabled. 11 Cisco 90-Day Limited Hardware Warranty Terms There are special terms applicable to your hardware warranty and various services that you can use during the warranty period.
