As the digital network is expanding so quickly, many applications are widely used in the social living, especially wireless LAN and IP telephone. The DTE(Data Terminal Equipment) based on Ethernet are also used in many place, these equipments have low power cost, but commonly they have very high requirements in stability and reliability of power supply. This article brings forward a system solution project of long-distance centralize power supply, which can be controlled by network, according to the 802.3af standard. And also presents the key technology in this solution.
