Installing a Cisco XR 12404 Router

Installing the Center-Mounting Brackets—Optional

If you plan to install the Cisco XR 12404 Router in the center-mounting position, you must first install the center-mounting brackets on the equipment rack rails, then secure the chassis to the center-mounting brackets. If you do not plan to use the optional center-mounting brackets, proceed directly to the “Installing the Chassis in a Rack” section on page 3-7.

The optional center-mounting bracket installation kit ships in an accessories box included in the Cisco XR 12404 Router shipping container.

Refer to Figure 3-2and use the following procedure to install the optional center-mounting brackets.

Step 1 Measure and mark the hole at the same height on both the left and right posts.

Step 2 Hold the right bracket against the right rack rail and align the bottom screw hole in the bracket with the marked screw hole.

Step 3 While supporting the bracket against the rack rail with one hand, use the other hand to insert a screw through a hole in the center-mounting bracket that aligns with a hole on the rack rail.

Step 4 Use your fingers to tighten the screw.

Step 5 Insert a second screw in the top hole in the bracket and finger tighten the screw. Step 6 Use a screwdriver to tighten all the screws.

Step 7 Mount the left center-mounting bracket so that it is at the same height as the right bracket.

Step 8 Use a level to ensure the two brackets are level; or use a measuring tape to ensure the both center-mounting brackets are the same distance from the top of both rack mounting rails.

Step 9 Use a screwdriver to tighten all the screws.
