cat 6509 48 port rj45 card

[b.withrow]

Twice now our company has seen groupings of switchports on a 48 port card go bad. This morning it happened to be ports 25-36 and we can't explain it. The ports were still UP and exchanging ARP but I couldn't ping any device in any of those ports. I wanted to reset the entire module but I can't effect 48 servers on our backbone all at once. Has anyone had experience such as this? I am looking for a way to diagnose this in the future. I know when I call the TAC and open a case I will have no problem getting an RMA for the module, but that means downtime, and I would like to avoid that if possible.

Info: we had "similar" problems, always with 1 group of switchports. RMA's for different modules on differents switches (all 65XX) did not solve the problem. The customer is now observing the temperature of the box as the event doesn't occurs regularly (every year 2-5 times). If you face the same problem again after a RMA, I recommend to observe the temperature.

Thanks for the reply. That's a great idea. Since this has already happened twice I would like to do as you suggest. How is the customer checking the temperature? On the chasis or in the room? Because our room is very climate controled, but maybe it's in a hotspot.

I've same kind of problem, sometimes , the reason? unknown!

Another thing is CiscoWorks 6.1 says unsupported module. The reason? I would like to know! Any suggestions?
