CAUTION:
Power is present in the media gateway even if the AC power cable is unplugged. When
procedures require ALL power to be removed from the media gateway and to prevent
unnecessary discharging of the battery, turn off the main circuit breaker located on the
front of the power distribution unit. This disconnects any batteries.
