Step 1 Make sure that the port adapter latch is in the locked position and the screw is tightened.

Step 2 Make sure the rack brakes are locked or the rack is stabilized.

Step 3 Position the router so the front is closest to you and lift it carefully into the rack. To prevent injury, avoid any sudden twists or moves.

Step 4 Slide the chassis into the rack, pushing it back until the brackets meet the mounting strips or posts on both sides of the rack.

Step 5 Keeping the brackets flush against the posts or mounting strips, align the holes in the brackets with the holes on the rack or mounting strip.

Step 6 For each bracket, insert and tighten two 12-24 x 0.5-inch screws to the rack.

This completes the procedure for installing the chassis in the rack. Proceed to the “Attaching a Chassis Ground Connection” section on page 2-11to continue the installation.
