We have Communication Media Module (WS-SVC-CMM) mounted on 6513 switch. It went down twice and we brought it up by applying "power enable module".
Could you please advise the reason of that?
Have upgraded the software lately?
If yes you may want to revert back to the old version, if not you may have a hardware failure

Thanks Reza for the reply!
I actually haven't upgraded its software and I also suspect it's a hardware failure as it happened twice.
Can you please post the "sh logs"? I am interested to see the event logs of the time when the line card went offline.
unfortunately I haven't the logs at the failure time and this is the problem but we periodically monitor the core and we transfer all its logs to a syslog server.
I'll post the logs if it happens again.
Thanks a lot!
