Errors on 3548XL

Hi,

I have a switch 3548XL. Last week it lost the connection with other switches, I checked the log and I found these errors:

FOUND an unknown transceiver on port 0

FOUND an unknown transceiver on port 1

FOUND an unknown transceiver on port 2

.

.

FOUND an unknown transceiver on port 52

what does this mean? is it a physical problem or ...?

I hope you can help me

Thanks in advance!

Re: Errors on 3548XL

Your switch has failed. If you have a contract, open a TAC case and have it replaced
