Amosphere NPM Installation Procedures (MMDS)
Install the RFSS Modules
If the configuration of your NPM basestation does not require a full complement
of RFSS modules, some slots may be covered with filler panels.
 To insert the RFSS modules in the RF rack
1 Remove the RFSS module from its protective bag.
2 Orient the RFSS module so that the text on the front panel is right-side up.
3 Slide the RFSS module into the first available RFSS slot. The slots should be filled
from bottom to top, left to right.
4 Secure the module in the slot using four #2 Phillips thumb screws, one in each
corner. Torque the thumb screws to 12 inch-pounds.
5 Ensure that the RFSS module is secure by grasping the handle on the front panel
and pulling lightly. The RFSS module should not move.
If the RFSS module does move, ensure that the mounting screws are attached to
the shelf assembly and that the module is seated correctly. If necessary, remove
the module and repeat this procedure.
6 Repeat steps 1 to 5 for the remaining RFSS modules.
!
CAUTION: Each RFSS module weighs approximately 14.1 kg
(31 pounds).
