Installing the Router in a Rack
Installing the Router Chassis in the Rack
To install the router chassis in the equipment rack, perform these steps:
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.
Caution 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.
