GBIC not recognised on 3524 (Gigastack is recognised though)
Hi, I have a small setup of 2 X 3524 connected via Gigastack GBICS and they work fine. We recently went along to upgrade the switch fabric by adding another switch (3550) and connecting with 2 1000BASE-T (TX) GBIC`s (Copper GBIC) .The 3550 sprang into life and the lights came on, however the existing 3524 GBIC did not light up and show connectivity. I think I have seen this situation before at another site when you try to use these 2 GBIC types together in this switch fabric (ie - using 3524`s).
The GBIC`s I am using are tested workers from another site.
Any ideas would be very much appreciated. I am going back onsite out of hours shortly to try and resolve.

2 things to check. What is the software level on the 3500XL? It needs to be a minumim of Release 12.0(5)XW to support the 1000BaseT GBIC (WS-G5482). Also what cabling are you using between the 1000BaseT ports? If its 1000BaseT port to 1000BaseT then a fully-wired straight cable will work (the standard has intelligence built in to do the crossing for you). If one of the ends is a 10/100/1000 port then I think you will need to make up a special cross-over cable (this cable would work in both situations as well obviously)
