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.
