45.2 SC Board Replacement Procedure
In the unlikely event of a SC board failure, the Mediant 8000 automatically switches to
another available SC board and notifies users with an alarm. Replace the failed board
as soon as possible to restore the system to its engineered configuration. SC boards
are hot-swappable, where the board can be inserted and removed when the Mediant
8000 is under power.
SC board replacement consists of the following steps:
Replacing the failed SC board with a new board
Installing the Operating System (OS) on the replaced SC board (this step may be
typically skipped, because SC boards normally have OS pre-installed on them)
Configuring the IP address on the replaced SC board
Installing software on the replaced SC board and bringing it up

1. Unfasten the screws on the plate of the board.
2. Simultaneously press the red ejector buttons on the two black ejector/injector
latches on both ends and wait 10 sec for the Hot Swap blue LED to light,
indicating that the board can be removed.
