I just got a GBIC for my Cisco switch and a patch cord to go with it. The patch cord is split in two. One is red and the other is black. Does it matter which port on the GBIC these attach to? My initial thought is to just plug them in and if they don't work to switch them around. It is an Dual LC to SC patch cable. It looks like there is only one way the other end in so that should be easy. I don't have the other piece of gear yet so this is nothing important. I was just curious. Thanks! Greg
