Removing and restoring power to the Media
Gateway
1
For a multicarrier cabinet, set the emergency transfer switch to ON. This locks the PN in the
emergency transfer mode until the trouble is cleared.
2
Depending on which type of cabinet you are powering down, do one of the following:
•
In an AC-powered multicarrier cabinet, set the circuit breaker to OFF at the power-
distribution unit.
•
In a DC-powered multicarrier cabinet, turn off the DC power supply.
•
In an AC- or DC-powered single-carrier cabinet stack, turn off the power for each affected
carrier individually. The ON/OFF switch is located behind the:
— AC carrier’s WP-91153 power unit
— DC carrier’s 676B power unit
3
Power is restored by reversing the action taken above.
Restoring power will cause a restart. This process is described under EXP-PN in
in Maintenance Alarms Reference (555-245-102).
If a powered-down carrier contains a 676B power unit, the 676B must have been powered down
for at least 10 seconds for the unit to restart.
Removing and restoring power from the Media
Server
The media server is shut down from the media server Web interface.
To shut down a server:
1
On the Web interface main menu, under Server, click Shutdown This Server.
2
On the Shutdown This Server screen, choose one of the following options:
•
Delayed. This is the default option. When you choose this option, the system notifies all
processes that the server will be shut down. The system then waits for the processes to
close files and perform other clean-up activities before it shuts the server down.
•
Immediate. When you choose this option, the system does not wait for processes that are
running to terminate normally before it shuts the server down. When you shut the server
down immediately, data may be lost.
3
If you want the server to reboot after shutdown, click the check box next to After shutdown,
restart system.
4
Click Shutdown.
If you selected a delayed shutdown, you will see the
shutdownproc accepted
message, indicating
that the global shutdown is in progress. An immediate shutdown terminates contact with the server so no
message is displayed.
