Abstract:
In order to increase the number of the powered devices that can be supported by the Ethernet power supply system, the present invention proposed to equip the powered device with an electrical energy storage device, namely shift the power timely shift the power supplying capability of the power sourcing equipment. The power sourcing equipment charges the electrical energy storage device, and then the powered device is supplied by the electrical energy storage device under usual situations. Thus the number of the powered devices that can be supported by the Ethernet power supply system is increased without increasing the supplying capability of the electrical quantity of the power sourcing equipment. Using the solution in the present invention, the capacity of the powered devices in the POE system is increased without having to change the hardware of the power sourcing equipment, and without having to change the wiring.
