Macro Base Station Installation Procedures (NPM-1000)
Attach the Radio Shelves to the Radio Rack
Depending on the configuration of your base station, there may be one, two, or three radio shelves
that need to be installed. The radio shelves are installed in the bottom three bays in the radio rack. If
your base station uses fewer than three radio shelves, you need to add filler shelves to the empty bays to
ensure the required airflow to the occupied bays.
 To attach the radio shelves to the radio rack
1 Remove the radio shelf from its protective bag.
NOTE: Each shelf weighs approximately 6.3 kg (14 pounds) before it is filled with
cards.
You can distinguish the radio shelves from the utility shelf by reading the
manufacturer’s label on the shelf.
2 Slide the radio shelf into the lowest available radio shelf bay in the radio rack.
If the bay is too tight to accommodate the radio 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 radio 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 radio shelf screw location.
4 Secure the radio 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 the 5/16-inch screws on any loosened cable troughs.
7 Repeat steps 1 to 6 for the remaining radio shelves.
WARNING: Your base station may arrive with the utility and radio shelves
already populated with cards. If this is the case, ensure that you are properly
grounded before handling the shelves. Failure to do so may damage the cards.
