Rack-Mounting the Router
Cisco 2811, Cisco 2821, and Cisco 2851 routers can be installed in 19- and 23-inch (48.26-cm and 58.42-cm) racks. Cisco 2801
routers can be installed only in 19-inch racks, and cannot be center mounted. 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-inch rack.
You can mount the router in the following ways:
• Center mounting—Brackets attached in the center of the chassis with only the front 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
The brackets are shown in Figure 4, Figure 5, and Figure 6.

Caution Do not overtorque the screws. The recommended torque is 15–18 in-lb (1.7–2.0 N-m).
