Abstract: Power-good detection device for a PoE system with multiple power source devices having multiple power source devices comprises an input to connect multiple power source devices, power state detection circuit to measure power state signals received by the input and power-good threshold generation circuit to generate a threshold value in response to an input control signal. The power-good detection device determines a power-good (normal) and a failure state of the power source devices based on the threshold value and provides a power-good state signal.

Abstract: Control device for power over Ethernet system having multiple power source devices controls power distribution to a plurality of communication ports. Master controller provides a power supply to power consumption look-up-table to a plurality of control circuits in various manners via a series bus. When one power source device shuts down, each control circuit can rapidly shut off selected port switches connected thereto.
