Cover Empty Radio Bays
Depending on the configuration of your NPM basestation, there may be empty
bays on the radio rack. Your basestation may arrive with the unused radio bays
already occupied with dummy shelves. If this is not the case or if the
configuration of your basestation has changed, you need to add dummy shelves
to any empty bays to ensure the required airflow to the occupied bays.
To cover the empty radio bays
1 Slide the dummy shelf into the lowest empty radio shelf bay in the radio rack. If the
bay is too tight to accommodate the dummy shelf, loosen the 5/16-inch screws
that hold the cable troughs to the rack. This should provide enough space for you
to slide in the dummy shelf.
2 Puncture a hole in the grounding tape for each dummy shelf screw location.
3 Secure the dummy shelf to the rack using eight 5/16-inch screws. Torque each
screw to 50 inch-pounds.
4 Retighten the 5/16-inch screws on any loosened cable troughs.
5 Repeat steps 1 to 4 for any remaining empty bays in the radio rack.
