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 3-2 and 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.
