Return to Task List

Ground plates are installed between stacked cabinets, provide the ground connection between cabinets, provide radio frequency (RF) radiation protection, and help stabilize the cabinets.

1. Loosen the four screws at the bottom of the top cabinet and at the top of the cabinet underneath the top cabinet. See Rear Panel Screw Locations.


2. Align the mounting holes in the rear ground plate over the bottom screws in the top cabinet. See Rear Ground Plate and Front Plate or Cabinet Clip -- Side View.


3. Align the mounting holes in the ground plate with the four holes at the top of the cabinet below the top cabinet. Slide the mounting plate down to seat on the screws.


4. Check all Time Division Multiplexing (TDM) bus cables and the Inter Cabinet Cables (ICC) to be sure they are not pinched by the plates.


5. Repeat Steps 1-3 until the rear ground plates are installed between all stacked cabinets.


6. Do not tighten the screws yet.
