Step 2 Place the cover on the base, with about 1 inch (25 mm) of clearance between the cover and the back

Step 3 Slide the cover back onto the base, making sure that the hook at the back edge of the cover, near the left

side, fits underneath the card cage on the back panel of the router.

Caution When replacing the cover, do not pinch the wires.

Step 4 Reinstall the rack-mounting brackets, and then reinstall the router in the rack.
