Installing Center-Mount Brackets—Optional
If you plan to install the router in the center-mount position, you must install the
center-mount brackets to the rack rails first. If you do not plan to use the optional
center-mount brackets, proceed directly to the
“Installing the Chassis
Rack-Mounting Platform” section on page 3-13.
The optional center-mount bracket installation kit ships in the accessories box
included with the router and contains the following:
• Two center-mount brackets.
• 10 (minimum) Phillips binderhead screws (usually provided with the bracket
kit) to secure the brackets to the mounting flanges (also called rails) in the
rack. Five screws should be installed on each bracket.
Contact a Cisco service representative for assistance if any parts are missing.
Note Make sure you have performed the measurements described in “Verifying Rack
Dimensions” section on page 3-8 before installing the center-mount brackets.
Use the following procedure to install the center-mount brackets to the rack rails.
