I have an interesting problem. I have a 6509 that I'm trying to swap the GBIC on. The switch is already using a GLC-SX-MM GBIC and it is up/up and passing traffic, but we are getting some errors and suspect it may be faulty.
I went to replace the GBIC with one of the identical model - a GLC-SX-MM. It was brand new, never been opened. When the new GBIC is plugged in the link light on the switch goes completely off (not amber) and the port goes into a down/down (notconnect) state. There are no messages in the logs at all. It's like it doesn't even see it. If you plug the old GBIC back in then the link comes back up. I tried a different port with the same results.
Thinking that the new GBIC may be faulty (even though it was brand new) I tried a second GLX-SX-MM, also new. That one does the same thing.
At that point I thought there might be a problem with that switch, so I tried the GBICs on the other 6509 in that pair. The other 6509 is running the same hardware and software. The GBICs will not work there either. If you move the old, suspected faulty GBIC from 6509-2 to 6509-1 then that it works.
The solution would seem to be that I have two faulty GBICs, but I'm having trouble persuading myself that I have two new ones, straight out of the package, that are both bad. Are there any other things anyone can think to check on the switch? Here's the pertinent information:

Can you try the SFP/GBIC on a different port and on a differents slot?
I am suspecting you could have an ASIC problem.
