Rack-Mount Installation Guidelines
•Allow sufficient clearance around the rack for maintenance.You need 36 in. (91.44 cm) of clearance to remove and replace
system components.
•Always place the heavier equipment in the lower half of the rack.
•If the rack is provided with stabilizing devices, install the stabilizers before mounting the chassis.
•Make sure that open or relay racks are bolted to the floor.
•When mounting the chassis in four-post or relay racks, use all the screws and brackets that are provided.
4 Installing the Chassis
The Cisco uBR7225VXR routers may be installed on a tabletop or rack-mounted. A rack-mount kit ships from the factory with
each router. The rack-mount kit includes the hardware used to mount the router in a standard 19-inch equipment rack or
Telco-type rack.
Attaching the Rack-Mount Brackets
Before installing the chassis in the rack, you must install rack-mount brackets on each side of the front, middle, or rear of the
chassis. (See Figure 4.) You can use the cable-management bracket if you are rack-mounting the chassis from the front. If you
are rack-mounting the chassis at the rear or middle of the chassis, both rack-mount brackets and the cable-management bracket
must be installed on the chassis before the chassis is installed in the rack.
