I have a 3660 Router with 12.3(14)T7 software. I have installed a NM-1GE, the card passes its self check and i get a green led for the EN led. I am also using a WS-G5484 so we can use fiber. I am connecting that card to s 3560G switch via the SFP port module. According to Cisco's website, I should be able to plug it in and it will get a link. In my case that is not happening,I need help with this very quickly.
