Routine Maintenance Procedures

To restore power to the cabinet:
1. Turn on the power in each cabinet individually. The power ON/OFF switch
is located behind the power unit:
■
WP-91153 Power Unit for an AC-powered system.
■
676B Power Unit for a DC-powered system
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.
2. Ensure that the translation card is properly inserted into the slot.
The system reboots. The translations are loaded from the translation card,
and rebooting takes about three minutes.
3. When system power is restored, a message appears on the administration
terminal.
The display is the same as a reset system 4, described in ‘‘Reset System
4 (System Reboot)’’ in Chapter 4, ‘‘Initialization and Recovery’’ .
4. After the system reboot is finished and all trouble is cleared, return the
EMER XFER (Emergency Transfer) switch(es) to AUTO.
This restores the system to the normal operating mode.
5. Use set time to reset the time.
6. Use display time command to verify your changes.
Restore Power to a Single-Carrier Cabinet EPN
NOTE:
Power may be restored to the EPN without affecting the PPN.
Follow these steps to restore power to AC- or DC-powered single-carrier cabinet
EPNs with or without high or critical reliability.
Before you start
In a high or critical reliability system, if power is to be removed from an individual
cabinet only, verify 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. T
■
Use status system to determine which Expansion Interface Link and
Tone-Clock are active.
■
Use display synchronization to determine the synchronization reference.
