Power source equipment

A power source equipment includes a plurality of network connection ports, a transceiver circuit, and a control circuit. Each of the network connection ports is coupled to a power device for supplying power to the power device. The transceiver circuit is coupled to the network connection ports to respectively receive uplink data of the corresponding power device from each of the network connection ports and respectively output a detection signal. The detection signal indicates the reception status of the uplink data of the corresponding network connection port. The control circuit receives each of the detection signals and performs a monitoring process for at least one of the network connection ports. The monitoring process is to reset the power supply to the corresponding network connection port while determining, according to the detection signal, that the corresponding network connection port has not received the uplink data for a cumulative period.
