This procedure applies to single-carrier cabinet EPNs with or without high or
critical reliability, where the cabinet is powered by either AC or DC power.
NOTE:
In a high or critical reliability system, if power is to be removed from an
individual cabinet only, make sure that the affected cabinet does not
contain an Expansion Interface circuit pack that is part of the Active
Expansion Link or an Active Tone-Clock. To determine which Expansion
Interface Link and Tone-Clock are active, issue the status system
command. To determine the synchronization reference, use the display
synchronization command.
1. To restore power to the cabinet:
NOTE:
If the cabinet is powered by a 676B Power Unit, the 676B must have
been powered off for at least 10 seconds before being powered on.
If not, the 676B Power Unit does not restart.
■ In an AC-Powered single-carrier cabinet system, turn on the power
in each cabinet individually. The ON/OFF switch is located at the
back of the cabinet behind the WP-91153 Power Unit.
■ In a DC-Powered single-carrier cabinet system, turn on the power
in each cabinet individually. The ON/OFF switch is located at the
back of the cabinet behind the 676B Power Unit.
2. The EPN circuit packs is inserted and the EPN is available for call
processing.
3. After the system reboot is finished and all trouble is cleared, return the
Emergency Transfer switch to AUTO. This restores the system to the
normal operating mode.
