Abstract
The present invention relates to device and method for detecting powered devices connected to a power source equipment in a Power over Ethernet system that provides multiple signal/power channels. A series of inspection signals including one discriminative signal is applied to the respective channels and response signals to the discriminative signal and other detection signals are compared in order to determine whether multiple channels are connected to one single powered device.
