Cisco :: Faulty Switch Or Bad Configuration

Have two switches configured and running 2 links to each other that are in a port channel. Now, I cannot get the 1 of the ports (Gi1/0/50) to come up at all, I've had the cable tested and replaced SFPs both ends. Switch A is a WS-C3750G-48TS and I believe the problem could be here, the last for GBIC ports, 2 of them we are using as links to Switch B in a port channel. Here is the config for both and the 'show int status' for both.
