Abstract
Methods and apparatus are disclosed for detecting ground faults in an Ethernet system. An Ethernet switch is configured to provide inline power to a plurality of ports each having positive and negative rails. Current is injected into selected rails of a port and ground isolation is temporarily broken for the port. A detected mismatch in current levels between the positive and negative rails of the port indicates a ground fault in the port.
