what is going on with this interface?
I can't trace this cable because the cable managment in the closet is so bad I can't determine what is on the other side. the port doesn't seem active because I don't see the light blinking. a TDR shows that there might be a short somewhere

As soon as I get the OK from my boss I will unplug the cable and see what happens.
