5500 Controller link down

I have a new 5500 controller and the fiber link shows down and I cannot get it to come up. Does anyone have any advice? I changed GBIC's fiber patch, ports etc and cannot get the link to come up. I did walk through the inital config as well.

Thanks.

Re: 5500 Controller link down

Are you getting error messages saying that the SFP modules you are using are fakes or non-Cisco supported?
