Issue with G5486 1000Base-LX Modules

Hello all. This may sound strange, but I am having difficulty getting a batch of G5486's working in our Chassie switch. Here's the details:

The switch I'm trying to put them in is a C4507R with current software on it. It's being put in the WS-X4418-GB card that is in the Chassie (18 Port GBIC card). The switch recognizes that the GBIC module is there but I cannot get any type of connectivity to occur, even though I know that the link is good.

Now, I have modules which do work, and their part # is 30-0703-01, but this batch that doesn't work is 30-0703-03. I can't seem to find any indication that a -03 model even exists anywhere, yet I have a whole batch of them. They DO work, however, in my C2950G series switches (24 and 48 port models), just not in the C4507R.

Any thoughts?

Hi

Have you checked up the logs in your 4507 to find out the possible reason for the inactivity on the port ?

Also can you try reversing the Rx/Tx of the Fiber patch cord which is getting to the GBIC ??

have you checked out the activity on the remote port too ? if yes whats ths status available on that port...

Yes, according to the 4507, the GBIC module is being detected and shows it as functioning. There doesn't appear to be anything different from it and the working ones. I had also tried reversing the Rx/Tx before, with no sucess. The remote port also shows no activity.

The only thing I can think of is that Cisco specifically designed the 4507 to only work with the 30-0703-01 models, and not the 03.

If this helps anyone, The 30

If this helps anyone, The 30-0703-01 is a WS-G5486 1000BASE-LX, but the 30-0703-03 is a WS-G5487 1000BASE-ZX
