Attaching the Chassis Rack-Mount and Cable-Management Brackets

This section explains how to install the rack-mount and cable-management brackets at the front and the rear of a Cisco 7401ASR router. Before installing the chassis in the rack, you must install a rack-mount bracket on each side of the front or rear of the chassis.

The parts and tools required for installing the rack-mount brackets and cable-management bracket are listed in the “Tools and Parts Required” section on page 2-2.

Determine whether you want the chassis to be flush-mounted or recessed. Figure 2-3shows the brackets being attached for a front rack-mount. Depending on the bracket holes you use, the router will protrude or be recessed in the rack.

To install the rack-mount and cable-management brackets on a Cisco 7401ASR router for a front rack-mount configuration, complete the following steps:

Step 1 Locate the threaded holes in the front sides of the chassis.

Step 2 Align the rack-mount bracket (1) to the side of the router. Depending on which set of rack-mount bracket holes you choose to use to attach the rack-mount bracket to the router, the chassis will either be recessed in the rack or protrude from the rack.

Step 3 Insert and tighten two screws (2).

Step 4 Repeat Step 1 through Step 3 on the other side of the router.

This completes the steps for attaching the rack-mount brackets to the Cisco 7401ASR router.

To install the cable-management bracket, go to “Attaching the Cable-Management Bracket” section on page 2-8. If you are not installing the cable-management bracket, go to the “Installing the Chassis in the Rack” section on page 2-9.
