Figure 2 Rack-Mounting Brackets for Cisco 3845 Routers
You can mount the router in the following ways:
• Center mounting—Brackets attached in the center of the router with either the front panel or the rear
panel facing forward
• Front mounting—Brackets attached at the front of the router with the front panel facing forward
• Rear mounting—Brackets attached at the rear of the router with the rear panel facing forward
Attaching Brackets to the Router for Rack Mounting
Attach the mounting brackets to the router, using a number 2 Phillips screwdriver to install the screws
provided with the brackets. Figure 3 through Figure 6 show bracket attachment locations, using a
Cisco 3845 router as an example.
Caution Do not overtorque the screws. The recommended torque is 10–12 inch-lb (1.1–1.4 N-m) for the
Cisco 3825 router and 15–18 inch-lb (1.7–2.0 N-m) for the Cisco 3845 router.
Caution Your installation must allow unrestricted airflow for router cooling.
