Remove and Replace the Top Cable Window
Use a step stool or a ladder to reach the top of the rack.
2.
Using a T-25 Torx screwdriver driver, loosely screw in the screws that secure the
panel to the top of the rack.
It might be necessary to move the panel slightly to align holes in the panel with the screw
holes in the rack frame. If they are misaligned, the screws might not thread correctly. Do not
finish tightening the screws until all six screws can be threaded straight into the holes without
interference from the panel.
3.
Finish tightening all of the screws.
4.
Open the front door and connect the grounding strap to the top panel.
Mate the two ends of the banana jack to complete the connection.
5.
If necessary, power on the rack.
See “Power On the Rack” on page 53 .
