Abstract:
1. A Power-over-Ethernet (PoE) relay system adapted to be electrically connected to a network power source unit including a PoE powering apparatus, a power supply to provide direct current (DC) power, and to an electronic product including a PoE powered apparatus, the PoE powering apparatus providing network data and network power carried on the network data, said PoE relay system comprising: a first networking cable; a PoE power injector adapted to be electrically coupled to the PoE powering apparatus via a second networking cable to receive the network data and the network power therefrom, further adapted to be electrically coupled to the power supply to receive the DC power therefrom, and gathering the network data, the network power and the DC power in a gathered signal group; and a PoE access bridge device electrically coupled to said PoE power injector via said first networking cable to receive the gathered signal group therefrom, and adapted to be electrically coupled to the electronic product, said PoE access bridge device receiving the DC power from the gathered signal group for operation, separating the network data and the network power of the gathered signal group from each other, and outputting the network power to the PoE powered apparatus of the electronic product via a third networking cable; wherein the DC power provided by the power supply has a voltage magnitude lower than that of the network power and conforming to a specification of a bias voltage of said PoE access bridge device, and said PoE access bridge device is configured to directly use the DC power to be needed power of said PoE access bridge device.
