Shutdown Procedures

In the event that you need to shut down the Media Gateway 3500, the correct
shutdown procedure should be followed.
To shut down a Media Gateway 3500, take these 5 steps:
1. Verify that no activity in the system is being generated from the EMS or MIB browser
due to operator activity.
Note:
2. From the EMS or MIB browser, verify that no activity such as board failure or
switchover takes place in the system for a duration of 5 minutes.
3. Lock the Media Gateway 3500 according to procedures detailed in the EMS User's
Manual.
4. Stop the SC application in the Active SC board by entering the command: tools tg
dn. Switchover takes place, in which the former Standby (Redundant) SC board
assumes Active (Master) board functionality. Stop the SC application in the second
SC board.
5. Using Telnet, connect to an SC board and enter the command, shutdown -i5 -g0 -y.
The board is shut down. Do the same to the second SC board.
Shutting off the power or disconnecting from the power source without first
following this procedure may cause serious damage to components of the
system.
The power feed to the media gateway can now be disconnected.
