Figure2-3 Attaching the Rack-Mount Brackets to the Front of the Chassis
Determine whether you want the chassis to be flush-mounted or recessed. Figure 2-3 shows the brackets
being attached for a front rack-mount. Depending on the bracket holes you use, the r outer 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:
Step1 Locate the threaded holes in the front sides of the chassis.
Step2 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 wil l either be rece ssed
in the rack or protrude from the rack.
Step3 Insert and tighten two screws (2).
Step4 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 th e
