Abrégé

A mark and hold system comprising a main power supply, a mark voltage power supply and a detection current source. After detection, and optionally classification, the main power supply is disconnected from the PD and instead the PD is connected to the mark voltage power supply. The detection current source draws current through a port resistance of the PSE and the PD. The detection current source draws current through a port resistance of the PSE and the PD. The voltage across the port resistance is monitored to determine whether the PD is still connected to the port.
