We recommend that you follow these rack specifications.

You can set up the Cisco N540-FH-CSR-SYS on a rack.

Before you begin this task, ensure that you have read and understood the safety warnings in the Preventing ESD Damage section of the Safety Warnings handout.

Before you connect the power or turn on the power to the device, you must provide an adequate device ground (earth) connection to your device.

This section describes how to ground the device. The grounding lug location is on the back panel of the device.

1. Verify that the ground cable is connected to the top of the rack and according to local site practice.

   

2. Attach one end of the shelf ground cable (#6 AWG cable) to the ground point on the rear of the chassis using the specified dual-hole lug connector.

   • Use a wire-stripping tool to remove approximately 0.75 inches (19 mm) of the covering from the end of the grounding cable.

   • Insert the stripped end of the grounding cable into the open end of the grounding lug.

   • Use the crimping tool to secure the grounding cable in the grounding lug.

   • Remove the adhesive label from the grounding pad on the chassis.

   • Place the grounding lug against the grounding pad so that there is solid metal-to-metal contact, and insert the two M4 screws with washers through the holes in the grounding lug and into the grounding pad.

   • Ensure that the lug and cable do not interfere with other equipment.

   • Prepare the other end of the grounding cable and connect it to an appropriate grounding point in your site to ensure adequate earth ground.

Refer Chapter 6: Replace Power Supply for more information about AC power cables installation.

To install the AC power cables in the power supply slots:

1. Plug the power supply cord in the power supply module.

2. Insert the power supply cord into the tie [1, 3] and tighten the tie around the power supply cord as shown in [2, 4] in the figure below.

   

   Note	These images are for only representation purposes. Certain variants of Cisco NCS 540 do not include a tie for the power supply cord.

Note	When installing DC power supply, use 12AWG, 90°C temperature rated cable. The recommanded cable length is three meters maximum from source. For lengths up to five meters, use 10AWG, and for lengths up to three meters, use 12AWG, 90°C temperature rated cable. For other lengths, contact Cisco.

Note	Always ensure that the building’s installation for short-circuit (overcurrent) protection does not exceed 15A. We recommend using a circuit breaker or a fast acting fuse with a maximum DC rating of 10A for over current protection.

Note	The DC connector or terminal block has an in-built screw and cage nut to which a torque of 1.3 to 1.8 N-m may be applied.

To attach the DC power supplies:

1. Locate the terminal block plug.

2. Insert the DC-input power source wires into the terminal block plug.

3. Attach the DC supply wires using the designated screws.

4. Use a ratcheting torque screwdriver to torque the terminal block plug captive screw. (See the following figure)

Depending on the chassis, you can use Quad Small Form-Factor Pluggable Plus (QSFP+), QSFP28, SFP, SFP+, and RJ45 connectors to connect the ports on the line cards to other network devices.

To prevent damage to the fiber-optic cables, we recommend that you keep the transceivers disconnected from their fiber-optic cables when installing the transceiver in the line card. Before removing a transceiver from the router, remove the cable from the transceiver.

To maximize the effectiveness and life of your transceivers and optical cables, do the following:

• Wear an ESD-preventative wrist strap that is connected to an earth ground whenever handling transceivers. The router is typically grounded during installation and provides an ESD port to which you can connect your wrist strap.

• Do not remove and insert a transceiver more often than is necessary. Repeated removals and insertions can shorten its useful life.

• Keep the transceivers and fiber-optic cables clean and dust free to maintain high signal accuracy and to prevent damage to the connectors. Attenuation (loss of light) is increased by contamination and should be kept below 0.35 dB.

  • Clean these parts before installation to prevent dust from scratching the fiber-optic cable ends.

  • Clean the connectors regularly; the required frequency for cleaning depends upon the environment. In addition, clean connectors when they are exposed to dust or accidentally touched. Both wet and dry cleaning techniques can be effective; refer to your site's fiber-optic connection cleaning procedures.

  • Do not touch the ends of connectors. Touching the ends can leave fingerprints and cause other contamination.

• Inspect routinely for dust and damage. If you suspect damage, clean and then inspect fiber ends under a microscope to determine if damage has occurred.

• The router must be fully installed in its rack, connected to a power source, and grounded.

• The necessary cabling for the console, management, and network connections must be available.

  • An RJ-45 rollover cable and DB9F/RJ-45 adapter are provided in the router accessory kit.

  • Network cabling should already be routed to the location of the installed router.

Before you create a network management connection for the router or connect the router to the network, you must create a local management connection through a console terminal and configure an IP address for the router. You also can use the console to perform the following functions (each of which can be performed through the management interface after you make that connection):

• Configure the router using the command-line interface (CLI).

• Monitor network statistics and errors.

• Configure Simple Network Management Protocol (SNMP) agent parameters.

• Download software updates.

The system console port is an RJ-45 receptacle for connecting a data terminal to perform the initial configuration of the router. The console cable is shipped with the hardware.

Note	Only RJ45 to DB-9 adapter cable is provided in the package.

Follow this procedure to connect a data terminal to the console port:

1. Set your terminal to these operational values: 115200 bps, 8 data bits, no parity, and two stop bits.

2. Attach the terminal end of the cable to the interface port on the data terminal.

3. Attach the other end of the cable to the console port.

You must complete the initial router configuration.

The management Ethernet port provides out-of-band management, which enables you to use the Command Line Interface (CLI) to manage the router by its IP address. This port uses a 10/100/1000 Ethernet connection with an RJ-45 interface.

Note	To prevent an IP address conflict, do not connect the management Ethernet port until the initial configuration is complete.

To connect cables to the system management port, attach Category 5 cables directly to the RJ-45 receptacle on the management Ethernet port.

Note	To comply with GR-1089-CORE, the intra-building port(s) of the equipment must use shielded intra-building cabling or wiring that is grounded at both ends.

1. Plug the cable directly into the RJ-45 receptacle.

2. Connect the network end of your RJ-45 cable to a switch, hub, repeater, or other external equipment.

The following sections describe how to connect timing cables.

The following sections describe how to connect cables from the router to a GPS unit for input or output timing of frequency:

1. Connect one end of a shielded coaxial cable to the GNSS RF IN port.

2. Connect the other end of the shielded coaxial cable to the GNSS antenna after the primary protector.

   Note	The GNSS RF In port should have a primary protector installed to meet the Local Safety guidelines.

   The GNSS RF In coaxial cable shield must be connected to the Facility Equipment Ground through the chassis. The chassis must have the ground wire connected to the Facility Equipment Ground.

This section shows how to install and remove transceiver module.

You can connect optical interface ports on line cards with other devices for network connectivity.

To maintain high signal accuracy and to prevent damage to the connectors, transceivers and fiber-optic cables must be kept clean and free of dust. Attenuation (loss of light) is increased by contamination and should be below 0.35 dB.

Consider the following maintenance guidelines:

• Transceivers are static sensitive. To prevent ESD damage, wear an ESD-preventative wrist strap that is connected to the grounded chassis.

• Do not remove and insert a transceiver more than it is necessary. Repeated removals and insertions can shorten its useful life.

• Keep all optical connections covered when not in use. Clean them before use to prevent dust from scratching the fiber-optic cable ends.

• Do not touch the ends of connectors. Touching the ends would leave fingerprints and cause other contamination.

• Clean the connectors regularly; the required frequency of cleaning depends upon the environment. In addition, clean connectors if they are exposed to dust or have been accidentally touched. Both wet and dry cleaning techniques can be effective; refer to your site's fiber-optic connection cleaning procedures.

• Inspect routinely for dust and damage. Clean and then inspect fiber ends under a microscope to determine whether any damage has occurred.
