Connecting Cables to RJ-45 Ports Cabling Considerations for 7705 Outdoor Enclosure Applications 3HE 19133 AAAA TQZZA 2022-2023 Nokia. Nokia Confidential Information Use subject to agreed restrictions on disclosure and use. 215 Making Connections to the RJ-45 Ports SAR-Hm and SAR-Hmc Chassis Installation Guide 10.2 Connecting Cables to RJ-45 Ports Warning:

Ensure that you read and observe all of the Dangers and Warnings described in the Mandatory Regulations and Site Preparation chapters before connecting cables to the 7705 SAR-Hm and 7705 SAR-Hmc. Ensure that cables are dressed such that they do not impede the insertion or removal of other equipment. To maintain EMC compliance, cables that are shielded and grounded at both ends must be used with interface connectors. To meet surge protection requirements, the cable shield for any open-ended cables must be grounded by attaching the shield to a convenient chassis or power supply ground point, using hardware suitable to provide a solid electrical and mechanical connection. In addition, ensure that there is sufficient strain relief to remove any mechanical strain on the ground connection due to cable movement. The 7705 SAR-Hm chassis supports two RS-232 ports, six 10/100Base-T Fast Ethernet (FE) ports, one Alarms port, and one Console port. The 7705 SAR-Hmc chassis supports two RS-232 ports in a single RJ-45 connector, three 10/100Base-T FE ports, one Alarms port, and one Console port. All ports have RJ-45 female connectors that require cables with RJ-45 male connectors. Figure 90 shows the location of the ports on the 7705 SAR-Hm. Figure 91 shows the location of the ports on the 7705 SAR-Hmc. When making a connection to an FE port, a shielded CAT5 (minimum) Ethernet cable grounded at both ends must be used to maintain EMC compliance. When making a connection to an RS-232 port, a shielded cable grounded at both sides must be used to maintain EMC compliance (an 8-conductor cable is required on the 7705 SAR-Hm and a 4-conductor cable is required on the 7705 SAR-Hmc). If a connection to both RS-232 ports on the RJ-45 connector is required on the 7705 SAR-Hmc, a 7705 SAR-Hmc RS-232 Y-Cable (3HE12554AA) is required. When making a connection to the Console port, a shielded cable grounded at least at one end must be used. When making a connection to the Alarms port, a shielded cable grounded at both ends must be used. For connections within the 7705 Outdoor Enclosure (a connection to the door alarm switch, for example) the shielded cable can be grounded at the 7705 SAR-Hmc Alarms port only. 216 2022-2023 Nokia.

wire stripper hardware for making the connection (such as a screw, star washer, and cable ties) To make a shield ground connection:

Step 1. Locate a convenient chassis ground point. Step 2. Carefully strip enough insulation (outer jacket) from the cable such that the exposed grounding wire can reach the chassis ground point. Ensure that there is enough stripped insulation to provide strain relief for the ground connection. Caution: When stripping the cable insulation, avoid nicking the ground conductors or the insulation on the signal conductor. Nicks can weaken or break a conductor or expose a wire to a potential short circuit. Step 3. Separate the ground shield (braid, foil, and drain wire) from the signal conductors. Step 4. Securely attach the shield to the chassis ground point. Use a screw and star washer large enough to make a proper ground connection. Use proper cable dressing and strain relief techniques. 10.2.2 Making Cable Connections Warning:

Ensure that you provide adequate strain relief (within a recommended distance of 1 to 2 ft (30.5 to 61.0 cm) of the connection point on the chassis) in order to prevent bending the cable when making the cable connection. For copper wire cables, maintain a minimum 1.2 in. (3.0 cm) bend radius within the allowable space. Required hardware:

cable ties (optional) 218 2022-2023 Nokia. Nokia Confidential Information Use subject to agreed restrictions on disclosure and use. 3HE 19133 AAAA TQZZA SAR-Hm and SAR-Hmc Chassis Installation Guide Making Connections to the RJ-45 Ports To attach copper wire cables:

Step 1. Attach the cables to the port connectors on the chassis. Step 2. Route the cables as described in Routing Cables. Step 3. Attach the other end of the cables to the far-end equipment. 10.2.3 Making External Alarm Connections The chassis is equipped with a copper RJ-45 female connector for external alarm connections, as shown in Figure 90. All alarm input/output interfaces are 5V tolerant, and the outputs can sink or source up to 100 mA of current. The external alarms interfaces are equipped with relays that can be used to trigger external alarm indicators. They also provide inputs that can be used to trigger the generation of alarms on the chassis to indicate environmental or external alarm conditions. Required hardware:

appropriate shielded cable with an RJ-45 male connector at the router end and a customized connector at the external devices end. Shielded cables must be used to maintain EMC compliance. To make an external alarm connection:

Step 1. Design the external alarm circuitry using the input and output pin assignments provided in Alarms Port Pinout Assignments. Step 2. Attach an appropriate connector at the external device end.

For a pole mount, the interconnecting communications wiring must not be strung from pole to pole unless equipped with suitable overcurrent and surge protection. If the Ethernet electrical connection between the chassis and another system is local

(on the same structure), surge protectors are not required but the systems must be grounded to the same ground rod. If the other system is on a different ground structure, it is highly recommended that an outdoor Surge Protection Device (SPD) be installed on each of the chassis Ethernet ports. The Ethernet ports are suitable for connection to metallic Outside Plant (OSP) cable conductors located at cell sites and other similar locations with tall antennas. The RS-232, Alarms, and Console ports on the chassis are suitable for connection to intra-building or unexposed wiring or cabling only. The intrabuilding ports of the equipment must not be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as intrabuilding interfaces only and require isolation from the exposed OSP cabling. The addition of primary protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring. 220 2022-2023 Nokia.

The topics include:

Overview and Prerequisites Powering Up the Chassis Establishing a Console Connection Troubleshooting Initial Startup Provisioning the 7705 SAR-Hm and 7705 SAR-Hmc 3HE 19133 AAAA TQZZA 2022-2023 Nokia. Nokia Confidential Information Use subject to agreed restrictions on disclosure and use. 255 Powering Up and Initializing SAR-Hm and SAR-Hmc Chassis Installation Guide 13.2 Overview and Prerequisites The primary copy of the 7705 SAR-Hm and 7705 SAR-Hmc software is factory-installed on an internal flash drive in directory cf3. When the 7705 SAR-Hm or 7705 SAR-Hmc is first powered on, by default the system searches for the bof.cfg file (also known as the BOF file) on the internal flash memory. The system reads and executes the system initialization commands configured in the boot option file (BOF). The BOF in the 7705 SAR-Hm and 7705 SAR-Hmc is factory-configured to run an automated initial commissioning process called ADP-Hm. ADP-Hm starts automatically the first time that the 7705 SAR-Hm or 7705 SAR-Hmc is powered on. It is possible to disable ADP after the 7705 SAR-Hm or 7705 SAR-Hmc is powered up for the first time. Refer to the 7705 SAR-Hm and 7705 SAR-Hmc Main Configuration Guide for information about how to disable ADP-Hm after the initial power-up. When using ADP-Hm to initialize the 7705 SAR-Hm or 7705 SAR-Hmc, the SIM must be installed in slot 1 before powering on the router. See Installing the SIM for more information. All prerequisites must be fulfilled before using ADP-Hm. Refer to the 7705 SAR-Hm and 7705 SAR-Hmc Main Configuration Guide for information about the ADP-Hm prerequisites. 256 2022-2023 Nokia. Nokia Confidential Information Use subject to agreed restrictions on disclosure and use. 3HE 19133 AAAA TQZZA SAR-Hm and SAR-Hmc Chassis Installation Guide Powering Up and Initializing 13.3 Powering Up the Chassis Note:

The chassis does not have a power switch or internal circuit breaker to turn the power ON or OFF. The 7705 SAR-Hm or 7705 SAR-Hmc is powered on by applying power from a low-voltage DC power source. The optional HV-PS35 can be used in facilities where a high-voltage DC or AC power source is available. For a DC power supply, use a DC-rated circuit breaker or a disconnect device to disconnect the system from the power supply. For an AC power supply, unplug the cord to disconnect the system from the power supply. 13.3.1 Power-up and Initialization To power up the chassis, follow these steps:

Step 1. Turn ON the power to the router at the remote DC power source to initiate the boot process. For systems using high-voltage AC or DC power, apply power to the HV-PS35 from the remote power source to initiate the boot process. Step 2. Verify that the system is initializing. The Status LED blinks green during initialization. The Alarms LED is off. The software image boots and the configuration file is loaded. If ADP-Hm is disabled, go to Step 4. Refer to the 7705 SAR-Hm and 7705 SAR-Hmc Main Configuration Guide for details about the ADP-Hm process steps and LED operation during the ADP-Hm process. Step 3. Verify that the ADP-Hm process starts to run. The Status LED blinks green when ADP-Hm is running and the Alarms LED begins flashing. Step 4. The Status LED turns solid green when initialization and the ADP-Hm process (if enabled) is complete. If the LEDs do not operate as described in the steps above, or if they blink and turn off, see Troubleshooting Initial Startup. Step 5. Verify the operational status of the ports by checking the LEDs on the front of the router. See 7705 SAR-Hm and 7705 SAR-Hmc LEDs. Step 6.

(Optional at this time if ADP-Hm is not used for initialization). After verifying the LEDs, establish communication with the router via the Console port. See Establishing a Console Connection. 3HE 19133 AAAA TQZZA 2022-2023 Nokia.

To establish a console connection, you need the following:

an ASCII terminal or a PC running terminal emulation software set to the parameters shown in Table 58 a shielded RJ-45 cable. Shielded cable must be used to maintain EMC compliance. See the Pinout Assignments chapter for more information. Table 58 Console Port Default Settings Parameter Gender Baud Rate Data Bits Parity Stop Bits Flow Control Value DCE 115 200 8 None 1 None To establish a console connection:

Step 1. Connect the terminal to the Console port on the front panel using a shielded RJ-45 cable. Step 2. Power on the terminal. Step 3. Establish the connection by pressing the <Enter> key a few times on your terminal keyboard. Step 4. At the router prompt, enter the login and password. Note:

For the 7705 SAR-Hm, the default login is admin and the default password is admin. The 7705 SAR-Hmc uses a unique one-time password for initial login. Information is provided on a notice card that is shipped with the chassis and in the 7705 SAR-Hm and SAR-Hmc Software Release Notes, Release 21.7.R1 and later. 3HE 19133 AAAA TQZZA 2022-2023 Nokia.

Configurations and executable software is stored locally in the on-board flash memory. The system boots up when power is applied to the chassis. The system is shipped from the factory with the BOF configured with an empty primary-config file, and with auto-discover enabled. Figure 108 displays the directory structure and file names on the integrated flash memory device with the suggested BOF configuration for the primary-config and primary-image files. The primary-config file is typically located at cf3:/config.cfg. Nokia recommends using the directory structure cf3:/TiMOS-SR-m.n.Yz to hold multiple releases. The location and filenames can be changed in the BOF if required. Figure 108 Files on the Integrated Flash Memory Device Root bof.cfg config.cfg TiMOS-SR-m.n.Yz both.tim and kernel.tim 26580 If the system cannot load or cannot find the bof.cfg file on the integrated flash memory device (cf3), the system prompts the user for alternate software and configuration file locations. The system will reboot continuously in an attempt to successfully find and load the file. If this happens, the faulty chassis must be returned to Nokia for replacement. Refer to 7705 SAR-Hm and 7705 SAR-Hmc Main Configuration Guide for a list of files on the integrated flash memory device.

On the 7705 SAR-Hm, the connector provides access to two sets of alarm output contacts and three alarm inputs. On the 7705 SAR-Hmc, the connector provides access to three alarm inputs. All alarm interfaces are rated for 5 VDC and 100 mA (source or sink). The alarm connector is classified for indoor use and permanent connection. Each of the three alarm inputs can be configured with the following:

name description administrative state (shut down or not shut down) detect and clear debounce timers association with up to four user-defined alarms with configurable descriptions, severity, and actions The alarm inputs must be associated with an alarm in order for them to be triggered. There is no Alarm Cut Off/Lamp Test (ACO/LT) button on the chassis. Alarm states must be cleared using a management interface (either CLI or SNMP). You can configure the alarm inputs using the configure>system>alarm-contact-

input CLI command and sub-commands. To display the status of the alarm inputs, use the show>system>alarm-contact-input all CLI command. Refer to the 7705 SAR-Hm and 7705 SAR-Hmc Interface Configuration Guide for more information. The pins on the external alarms connector can also be configured to trigger a log event with a configurable severity using the trigger-alarm-msg command in the configure>system>alarm-contact-input context. For information about how to configure the log events on the pins, refer to the System Alarm Contact Input Commands section of the 7450 ESS, 7750 SR, 7950 XRS, and VSR Basic System Configuration Guide.
