Powered device and power over Ethernet system

The invention provides a powered device and a power over Ethernet system, and belongs to the technical field of Ethernet power supplying. The powered device comprises a plurality of powered controllers, a plurality of switching circuits, a slow starting circuit, a voltage converter and a load circuit, wherein each switching circuit is connected with one corresponding powered controller, and can keep a turn-off state during the handshake stage of the powered controller and power souring equipment, so that the connection between the powered controller and the load circuit can be cut off, influence of the load current of the load circuit to the normal power-on of the powered controller is avoided, the normal power-on of the powered controller can be ensured, and hot plugging of the powered controller is realized. In addition, the slow starting circuit is further arranged in the powered device, and the slow starting circuit has a slow starting function, so that it is ensured that an inputcapacitor of the voltage
