Abstract: A PoE powered device and method of operation are provided. The device includes a first port unit configured to negotiate receipt of a level of PoE power from a power sourcing equipment. The power is received on a first pair of taps on a first communication port. A detection unit is configured to detect a presence of a first optional circuit load and to detect a presence of a second optional power load. A control circuit is configured to establish connectivity between a second pair of taps on the first communication port and a second powered device port unit in response to the detection unit detecting the first optional load, and further configured to establish connectivity between the second pair of taps and a third pair of taps on a pass-through communication port in response to the detection unit failing to detect the first load and detecting the second load.
