11. Rollback the Secondary SC board (if it exists).
•
Rollback of the Secondary SC board is similar to the rollback of the Primary SC
board described above. However, it is important to rollback a Primary SC board
first, which minimizes the downtime frame when the Avaya G860 Media Gateway
is not functioning. If the Primary SC board has been removed, media gateway
service is not restored until the rollback of the Secondary board is completed.
(The system is in simplex configuration - dependent upon only one SC board.)
12. Rollback the Media Gateway boards.
•
The Media Gateway boards are automatically reset by the SC software and rolled
back to the previous software version. You are not required to take any additional
measures to accomplish this.
13. Rollback the Ethernet Switch boards.
•
