ABSTRACT:
A physical layer device that is adapted to communicate with a cable medium and that includes an indicator comprises a first input/output terminal and a first transceiver that communicates with the first input/output terminal that is adapted to be connected to the cable medium. A detector detects a power over Ethernet (POE) device. A switching device selectively provides power from a power supply over the cable medium when the detector detects the POE device. A cable tester communicates with the first transceiver, tests the cable medium and determines a cable status, and delays testing of the cable medium when the detector detects the POE device until the switching device provides the power. The indicator indicates at least one of cable testing status during the test and the cable status after the test.
