| Abstract: | The power supply for traditional network equipment all need local AC power source, which increases the cost of network base construction and may affect the network equipment once the power is cut off. This paper analyses the basic priciple and development of power over Ethernet technology through which both datas and power can be transmitted, and briefly introduces the reference design of power over Ethernet equipment combined with a power supply manage chip according with power over Ethernet technology standard. |
