Prerequisites

Before installing the Cisco ASR 914 Router, it is important to prepare for the installation by:

• Preparing the site (site planning) and reviewing the installation plans or method of procedures (MOP)

• Unpacking and inspecting the Cisco ASR 914 Router

• Gathering the tools and test equipment required to properly install the Cisco ASR 914 Router

For more instructions on how to prepare for the installation of the Cisco ASR 914 Router, see the Preparing

for Installation section.

Installing the Router in a Rack

The following sections describe how to install the Cisco ASR 914 Router in a rack:

Installing the Chassis Brackets

The chassis is shipped with mounting brackets that can be installed on the front or rear of the chassis. To

install the brackets on the front of the chassis, perform these steps:

Installing the Cisco ASR 914 Router

Procedure

Step 1 Remove the rack-mount brackets from the accessory kit and position them beside the router chassis.

The figure below shows how to attach the brackets on the Cisco ASR 914 Router for the 23-inch rack.

Figure 1: Attaching Mounting Brackets for the 23-inch Rack

Step 2 Position one of the brackets against the chassis side, and align the screw holes.

Step 3 Secure the bracket to the chassis with the screws removed when performing Step 1. The recommended

maximum torque is 28 in.-lb (3.16 N-m).

What to do next

Repeat Step 2 and Step 3 for the other bracket.

Installing the Router Chassis in the Rack

The procedures in this section apply to both horizontal and vertical mounting of the router in a rack.

Installing the Router Chassis in the Rack

To install the router chassis in the equipment rack, perform these steps:

Procedure

Step 1 Position the chassis in the rack as follows:

• If the front of the chassis (front panel) is at the front of the rack, insert the rear of the chassis between

the mounting posts.

• If the rear of the chassis is at the front of the rack, insert the front of the chassis between the mounting

posts.

Step 2 Align the mounting holes in the bracket (and optional cable guide) with the mounting holes in the equipment

rack.

Do not use interface module and power supply ejector handles to lift the chassis; using the handles

to lift the chassis can deform or damage the handles. Installing the Chassis to support the Japanese

JIS Rack Standard.

Step 3 Install the 8 or 12 (4 or 6 per side) 12-24 x 3/4-inch or 10-32 x 3/4-inch screws through the holes in the bracket

and into the threaded holes in the equipment rack posts.

Step 4 Use a tape measure and level to verify that the chassis is installed straight and level.

Installing the Patch Panel on the Rack

A patch panel serves as a static switchboard, using cables to interconnect networks and manage fiber optic

cables. A patch panel uses patch cords, to create each interconnection. Circuits can also be rearranged by

plugging and unplugging respective patch cords. Patch cords connect the ports in the patch panel to ports in

the network switch, which creates permanent port connections to the switch. Patch panels are based on the

number of ports they contain, with 48-port, 24-port and 12-port panels.

Installing the Patch Panel on the Rack

This procedure installs the Patch Panel on the Rack.

Procedure

Step 1 Assemble the patch panels on the opposite side of the rack to make the cable routing process easy.

Step 2 Fix one patch panel with a minimum of two screws on each side.

Installing the Chassis Ground Connection

Before you connect the power or turn on the power to the Cisco ASR 914 Router, you must provide an adequate

chassis ground (earth) connection to your router.

This section describes how to ground the Cisco ASR 914 Router chassis. The router provides two locations

for attaching a 2-hole grounding lug according to the rack-mounting brackets you use to install the router.

It is sufficient to connect only one grounding lug.

Note

Installing the Chassis Ground Connection

Figure 4: Attaching a Grounding Lug to the Rear of the Router

Grounding lugs1,

To ensure that the chassis ground connection is adequate, you need the following parts and tools:

• Ratcheting torque screwdriver with Phillips head that exerts up to 15 in.-lb (1.69 N-m) of pressure for

attaching the ground wire to the router

• Crimping tool as specified by the ground lug manufacturer

• 6 or 8 AWG copper wire for the power cord

• 6 AWG or larger copper wire for the ground wire

• Wire-stripping tools appropriate to the wire you are using

Before making connections to the Cisco ASR 914 Router, ensure that you disconnect the power at the circuit

breaker. Otherwise, severe injury to you or damage to the router may occur.

Caution

This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence

of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician

if you are uncertain that suitable grounding is available. Statement 1024

Warning

Installing the Cisco ASR 914 Router

Installing the Chassis Ground Connection

Use copper conductors only. Statement 1025

Warning

When installing the unit, the ground connection must always be made first and disconnected last. Statement

Warning

This unit is to be installed in a restrictive access location and must be permanently grounded to minimum 6

AWG copper ground wire.

Perform the following procedure to ground the Cisco ASR 914 Router using a 2-hole lug and the corresponding

mounting point. Most carriers require a minimum 6 AWG ground connection. Verify your carrier’s requirements

for the ground connection.

Procedure

Step 1 If your ground wire is insulated, use a wire-stripping tool to strip the ground wire to 0.5 inch ± 0.02 inch (12.7

mm ±0.5 mm).

Figure 5: Stripping a Ground Wire

Step 2 Slide the open end of your 2-hole ground lug over the exposed area of the ground wire.

Step 3 Using a crimping tool (as specified by the ground lug manufacturer), crimp the ground lug to the ground wire

as shown in the figure below.

Figure 6: Crimping a Ground Lug onto the Ground Wire

Step 4 Use a Phillips head screwdriver to attach the 2-hole ground lug and wire assembly to the router with the 2

pan-head Phillips head screws. For a 23-inch EIA rack, attach the 2-hole ground lug to the front or the rear

of the router.

Step 5 Connect the other end of the ground wire to a suitable grounding point at your site.

Installing the Fan Tray (A914-F2B-AIR-FAN)

The fan tray is a modular unit that provides cooling to the Cisco ASR 914 Router. Follow these steps to install

the fan tray in the chassis:

When removing the fan tray, keep your hands and fingers away from the spinning fan blades. Let the fan

blades completely stop before you remove the fan tray. Statement 258

Warning

Procedure

Step 1 Insert the fan trays gently inside the flap door to allow smooth entry of the fan as shown below. For more

instructions, refer to the caution label on the flap door.
