That looks like a 1000/1100. For those, I get my ports here. Gone through 12 and the one time I had a problem, it definitely wasn't the port's fault.

The port is just a passthrough. You can use a breakout board to test each pin for continuity from front to back. If they all check out, it's not the port itself. Also take into account the possibility of residual flux inside the port and/or on the cable you've plugged into them.
