Abstract
Power sourcing equipment for power over Ethernet (PoE) includes a power supply control circuit, an Ethernet port, and a surge protection circuit. The surge protection circuit includes a first circuit, a second circuit, and a common discharge circuit. The first circuit is connected to a power supply pin group of the Ethernet port, the power supply control circuit, and the common discharge circuit. The second circuit is connected to a non-power supply pin group of the Ethernet port and the common discharge circuit. The first circuit transmits, to the common discharge circuit, a first surge that is input from the power supply pin group. The second circuit transmits, to the common discharge circuit, a second surge that is input from the non-power supply pin group. The common discharge circuit discharges the first surge and the second surge to ground.
