Rack-Mounting Bracket Installation
The mounting brackets temporarily bear the weight of the router while it is being
positioned in the rack for permanent installation. These brackets can be left in
place following router installation.
Two or more people should install the router to minimize the risk of personal
injury and damage to the equipment.
Installing the mounting brackets is presented in this section.
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
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
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.
