FCX Fiber ports not working

We received some new FCX 48's. I'm using one as a simple layer 2 switch with a fiber backbone to a SuperX. No ports are tagged and no VLANs except default 1.

The port shows enabled, but I understand there is nothing I need to do except plug in the gbic and it works. I swapped it with a 4802 using the same gbic and fiber link and the 4802 talks to to the SuperX and is working fine.

FCXS07001b on the FCX.

e 1/1/1 shows down on a show int brief.

spanning tree is disabled.

This switch is straight out of the box with minimal config changes. After reading the manual, I've been playing with the gig auto config, but it doesn't make a difference.

Am I missing something simple? The same gbic and fiber work on a 4802 and at the moment, all I want to use this for is a straight, simple layer 2 switch.

Re: FCX Fiber ports not working

Hi,

     Do you have anything plugged into the RJ45 port number 1?  This is a shared or combo port on the FCX.

     There shouldbe no need to use the gig auto command/

Thanks

Michael.
