• 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:

1
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

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.

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

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
42
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.

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.
