Re: g5483 cisco 3550 - 48 - smi

Could be a bad GBIC. But I would try a software upgrade first: the 3550 switches are up to 12.1(19)EA1c posted yesterday, or 12.1(20)EA1 posted Feb 10, 2004.

I assume you don't have any other WS-G5483 1000BASE-T GBICs to test swapping modules; or any other 3550 switches with open GBIC slots to see if the suspected GBIC also fails to be recognized there.

Hope this helps.
