Installing the Chassis
Youcan set the chassis on a desktop or install it in a rack. A chassis of 1 RU height can also be mounted on a wall or other flat
surface. See the applicable instructions in the following sections:
•Rack-Mounting the Chassis, page 9
•Wall-Mounting the Chassis—1-Rack-Unit (RU) Chassis Height Only, page12
•Installing on a Desktop, page 13
Caution Toprevent damage to the chassis, never attempt to lift or tilt the chassis by the plastic panel on the front. Always
hold the chassis by the metal body.

Rack-Mounting the Chassis

Cisco 2600XM series and Cisco 2612 routers can be installed in 19-, 23-, and 24-inch racks. Use the standard brackets for
mounting the chassis in a 19-inch rack; use the optional larger brackets for mounting the chassis in a 23- or 24-inch rack.
You can mount the chassis in the following ways:
•Centermounting—Brackets attached in the center of the chassis with either the front panel or the rear panel facing forward
•Front mounting—Brackets attached at the front of the chassis with the front panel facing forward
•Rear mounting—Brackets attached at the rear of the chassis with the rear panel facing forward
