You can mount the router in the following ways:

•Center-front mounting—Brackets attached in the center front of the chassis with only the front panel facing forward.

•Center-back mounting—Brackets attached in the center back of the chassis with only the back panel facing forward.

•Front mounting—Brackets attached at the front of the chassis with the front panel facing forward.

•Back mounting—Brackets attached at the back of the chassis with the back panel facing forward.

Attaching Rack-Mount Brackets

Attach the mounting brackets to the router chassis as shown in Figure 3-1through Figure 3-4, using the screws provided.

Caution Do not over-torque the screws. The recommended torque is 15 to 18 inch-lb (1.7 to 2.0 N-m).

Attach the second bracket to the opposite side of the chassis. Use a number-2 Phillips screwdriver to install the number-8 bracket screws.

Caution Your chassis installation must allow unrestricted airflow for chassis cooling.
