I have a WS3750g-12s running IOS ver 12.5(25)SEB2. I have 9 ports configured as routed
ports, 8 of which goto seperate IDF's. The ninth port I want to use as an uplink to my
Firebox X2500. The problem is the 3750 has all fiber ports and the Firebox has all
RJ-45. I purchased a glc-fe-100fx tranciever and a CyberXLinkj CXL3M1-2 Media converter to connect the two. The twisted pair half of the media converter lights up fine however the FX side of the media converter is unlit. I tried turning off the auto negotiate property under the Cisco's port speed config but this made no difference. I than tried other media in the port. Plugging in a GLC-SX-MM into the same port and connecting the other end to one of my 3560-48's fiber port gives an almost immediate link light (portfast) on both devices. I then tried the glc-fe-100fx all by itself, and the when I plug it in I get the following error from the switch:
"gbic-invalid error detected on gb0/12, putting gb0/12 in err-disable state"
I get this error in any gbic on any of my Cisco's. Cisco documentation says that this error indicates a bad SFP, but this was bought new less than a month ago. Is there anything else I should check before assuming this is a bad SFP?
