If you can not connect via Telnet/SSH to some SC board, take these 3 steps:
a.
Reboot the SC board by pressing
RESET
button on its front panel or pulling
it out of the chassis and re-inserting it back in.
b.
Wait for 5 minutes until SC board completes the reboot.
c.
Login to the board via Telnet/SSH as
root
user and stop the Media Gateway
software on it as described in step 4.

If you still cannot connect to a specific SC board via Telnet/SSH after completing
the previous step, then it’s highly likely that there is a hardware failure on the
board or a severely incorrect software configuration. Remove the failed SC board
from the chassis. For details on replacing a failed SC board, see 'SC Board
Replacement Procedure' on page
Note:
It is important to stop the Media Gateway software on
both
of the SC boards
and remove the failed SC boards from the chassis prior to proceeding to the next
step.
