Replacing a Power Module
Follow the steps below to replace a PM:
1.
Be sure you are wearing an ESD strap when handling PMs.
2.
Confirm that you have approximately seven inches of clearance from the rear of the PM and any RF cabling in order to
remove the module. If removal of RF cabling is required for clearance, be sure to label the cables appropriately first.
CAUTION: If no redundant PM is installed, replacing a PM will interrupt service.
3.
Confirm the other PM and power feed is currently functioning. Flip down the hinged front panel at the bottom of the
chassis and ensure that both its LEDs are green.
4.
At the rear of the chassis, power off the PM to be replaced by pushing the Main breaker to the off position.
5.
Remove the power cable and unscrew the two captive fasteners on the rear of the PM.
