thanks for message

But this supervisor has been already operate in 4503-E(operate normal).We rip this from 4503-E chassis and took it our failed 4503-E chassis. I think, if it has older IOS it didn't operate other 4503-E chassis.

You are probably right and are running right version. I would suggest putting in a TAC case on the chassis. Sounds like something might have gone wrong with the backplane on the chassis.

hmm oke. ı found what is TAC. but ı think it couldn't solve my problem.

TAC will assist you in troubleshooting or RMA a faulty product. You must have a smartnet contract to be able to do this. If you are able to open a TAC case they will be able to solve your problem.
