Decommissioning occurs whenever an NPM is taken out of service or moved to a
new location.
 To decommission an NPM
1 Shutdown the radio sector controllers:
i Establish an SSH session with each card, as described in the Amosphere
Maintenance Procedures.
ii Shutdown each card by typing:
shutdown now ↵
2 Shutdown the application hosts using the procedure described in step 1.
3 Shutdown the standby utility bus controller using the procedure described in step
1.
A utility bus controller is in standby mode when the USR2 status light is off.
4 Shutdown the active utility bus controller using the procedure described in step 1.
A utility bus controller is in active mode when the USR2 status light is green.
5 Power off the NPM by setting CB01 through CB14 to the OFF (down) position.
6 Power off the main power supply for the NPM. With most power bays, circuit
breakers control the three +24V DC feeds to each NPM rack. Ensure that the main
power is removed for both the radio and RF racks.
See the documentation that accompanies your main power supply for specific
instructions on powering off the +24V DC feeds to the NPM.
After the main power supply is powered off, it is safe to prepare the NPM for
shipment or storage.
7 Package the NPM according to the procedures specific to your site. If you remove
the cards from their shelves, ensure that the cards are stored in antistatic
packaging and that the required documentation is included.
WARNING: Ensure that the necessary requirements and procedures
have been reviewed prior to the start of any power-related activity. Refer to
your power cut-over MOP for procedures specific to your site.
