Tools and Equipment Required
You need the following items to install the optional center-mount rack-mounting
brackets:
• Number 2 Phillips screwdriver
• Tape measure (optional)
• Level (optional)
Installing the Optional Center-Mount Brackets
To install the center-mount brackets, see Figure 3-2 and follow these steps:
Step 1 Measure and mark the hole at the same height on both the left and right posts.
Caution When installing the right side lower center-mount bracket, ensure that the bracket
does not impede airflow through the air filter, which could cause overheating in
the router.
Step 2 Mount the lower right bracket:
a. Hold the lower right bracket against the right rack rail and align the bottom
screw hole in the lower bracket with the marked screw hole.
b. Pick a bottom bracket hole that aligns with a hole in the rack rail, then insert
a screw in the hole and finger tighten the screw.
c. Insert a second screw in the top hole in the bracket and finger tighten that
screw.
Step 3 Repeat Step 2a through Step 2c to mount the lower left center-mount bracket so
that it is at the same height as the lower right 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.
Step 6 Repeat Step 1 through Step 5 for both upper center-mount brackets.
