Attach the Utility Shelf to the Radio Rack
The utility shelf is installed in the top-most bay in the radio rack.
 To attach the utility shelf to the radio rack
1 Remove the utility shelf from its protective bag. You can distinguish the utility shelf
from the radio shelves by reading the manufacturer’s label on the inside of the
chassis.
2 Slide the utility shelf into the top bay in the radio rack.
If the bay is too tight to accommodate the utility shelf, loosen the 5/16-inch screws
that hold the upper cooling unit and the cable trough to the rack. This should
provide enough space for you to slide in the utility shelf.
If any of the cable brackets interfere with the insertion of the radio shelf, remove
them. The cable brackets attach to the rack using 5/16-inch screws.
3 Puncture a hole in the grounding tape for each utility shelf screw location.
4 Attach the utility shelf to the rack using eight 5/16-inch screws. Torque each screw
to 50 inch-pounds.
5 Reattach any cable brackets you removed.
6 Retighten any 5/16-inch screws on the upper cooling unit and the cable trough.
