Rik, You're probably right, not great advice. Could probably just switch the connectors around just as quickly to see if it works. I do it quite a bit, but that doesn't mean it's the right thing to do. Anyway, did I miss something? I didn't see anything about it being a copper GBIC on the 3508.

An LX GBIC uses a laser transmitter, which is powerful enough to burn a hole in your retina as a coworker of mine found out. Besides, this is a copper GBIC so no light to see. 12.0(5.3) is a new enough IOS to recognize the copper GBIC so this version will work on all of your 3500 switches.

First, check to make sure your fiber is connected correctly. When the switch is powered up, you can see which side the laser is on in the GBIC connector. Then, if you cup the fiber in your hands, briefly (very briefly) look to see which connector the laser is on. Then make sure that the connector with the laser goes to the connector on the switch without the laser. If this isn't the problem, there's a good chance it's probably a bad GBIC.

We had a 3550 that was doing the same thing (GBIC not blinking at all). We called into TAC and got a replacement. We did the upgrade first and when the switch would boot it would no recognize the Ethernet controller. It may be different for you since you have a 3508. I guess you would need to ask yourself "do I feel lucky?"

We tried to make operate it but the GBIC was not blinking at all , as I had read this document http://www.cisco.com/univercd/cc/td/doc/product/lan/c2900xl/1000gbic/ins tnot e.htm , I got conclusion that the switches detect and enable the GBIC only when they are running the minimum software releases which in case of Catalyst 3508G XL Cisco the minimum IOS Release is 12.0(5)XW , so in order to enable the GBIC we have to upgrade the IOS software from 12.0(5.2)XU to 12.0(5)XW . Second point: we have Catalyst 2950T-24 Switch-24 10/100 ports and 2 fixed 10/100/1000BaseT uplink ports, IOS available 12.0(5.3)WC(1). As I had read this document http://www.cisco.com/univercd/cc/td/doc/product/lan/cat2950/2950_wc/1169 303. htm , I got conclusion that we do not have to upgrade the ios image because the ios will support the following: Catalyst 2950T-24 24 fixed autosensing 10/100 ports and 2 fixed autosensing 10/100/1000 Ethernet ports. please tell me if there is something missing here , the equipment is placed far away from our office we need to put the network on there as soon as possible , in case we have to upgrade the ios of the any platform then please let us go ahead solving this issue.
