I have a WS-C3524-XL with 24 FastEthernet/IEEE 802.3 interface(s)
2 Gigabit Ethernet/IEEE 802.3 interface(s)
But when I try to insert a Gbic on it the interface don't recognizes it, it is like there nothing connected to it.
I did a research and found a document at cisco site saying the IOS that accepts this GBIC, but upgraded the IOS and no joy.
I hope someone can help me.
The old ios was c3500XL-c3h2s-mz-120.5.2-XU.bin
and the new is c3500xl-c3h2s-mz.120-5.WC17.bin
PS: I have 2 identical switches with this problem.
