7. Rollback the 1
st
SC board.
To restore the Media Gateway software from the pre-upgrade backup image, at
the prompt change directory to the place where backup file is stored (if it's not in
your home directory) and execute the backup file.
client208::./backup.bk
8. To start the Media Gateway software, type reboot. Press Enter.
client208::~# reboot
9. Rollback the 2
nd
SC board (if it exists).
• Rollback of the 2
nd
SC board is similar to the rollback of the 1
st
SC board
described above. However, it is important to rollback a 1
st
SC board first,
which minimizes the downtime frame when the Mediant Media Gateway is
not functioning. If the 1
st
SC board has been removed, media gateway
service is not restored until the rollback of the 2
nd
SC board is completed.
10. Rollback the Media Gateway boards.
• The Media Gateway boards are automatically reset by the Media Gateway
software and rolled back to the previous software version. You are not
required to take any additional measures to accomplish this.
11. Rollback the Ethernet Switch boards.
• Lock/unlock the Ethernet Switch boards one after another, to roll them back
to the previous software version.
