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 Hold the right bracket against the right mounting rail and align the bottom screw
hole in the bracket with the marked screw hole.
Step 3 While supporting the bracket against the mounting rail with one hand, use the
other hand to insert a screw through a hole in the rack-mounting bracket.
Step 4 Finger-tighten the screw.
Step 5 Insert a second screw in the top hole in the bracket and finger tighten the screw.
Step 6 Mount the left rack-mounting bracket the same as you mounted the right bracket.
Step 7 Measure the two brackets to ensure they are positioned at the same height.
Step 8 Use a level to ensure the tops of the two brackets are level, or use a measuring tape
to ensure that each bracket is the same distance from the top of both rack rails.
Step 9 Use a screwdriver to tighten all the screws ( Figure 3-1 ).
