Chapter 3 Installing the Cisco XR 12406 Router
Installing a Router
• Power cables and power supplies have been checked for compatibility with
your power service.
• Labels on the equipment have been checked to ensure that the power service
at your site is suitable for the router.
• AC power source receptacles are easy to reach.
Installing the Rack-Mounting Brackets—Optional
The rack-mounting brackets temporarily bear the weight of the router while it is
being positioned in the rack.
While the use of the rack-mounting is optional, installing them makes it much
easier to mount the router in a rack, and also ensures that the router is level. The
rack-mounting brackets can be left in place following the router installation.
Warning Two or more people should install the router to minimize the risk of personal
injury and damage to the equipment.
Refer to Figure 3-1 and use the following procedure to install the rack-mounting
brackets.
Step 1 Measure and mark the hole at the same height on both the left and right rack rails.
Step 2 Mount the right mounting bracket:
a. Hold the right rack-mount bracket against the right rack rail and align the
bottom screw hole in the bracket with the marked screw hole on the rail.
b. Insert a screw through the bottom hole in the bracket and finger tighten the
screw.
c. Insert and finger tighten a second screw in the top hole in the bracket.
Step 3 Follow Step 2 a through Step 2 c to mount the left rack-mount bracket.
Step 4 Use a level to verify that the tops of the two brackets are level, or use a measuring
tape to verify that both brackets are the same distance from the tops of both rack
rails.
Step 5 Use a screwdriver to tighten all the screws.
