See below for possible fixes:
- Unplug the network cable from the D9133TTL-E card. If the Ground Fault clears, plug the cable back into the D9133TTL-E card.
- Trace the network cable to the switch or hub and unplug it. If the ground fault clears, the cable is not causing the ground fault.
- Try connecting to a different port on the switcher or hub connection.
- Make a new network cable by using pins 1, 2, 3, and 6.
