Abstract

The invention discloses Ethernet power supply end equipment as well as a system and method thereof for realizing power supply. The Ethernet power supply equipment comprises two pairs of transformers of a physical-layer port, and a power supply end equipment manager; in addition, a pair of switches is connected between each pair of transformers and the power supply end equipment manager respectively; wherein one switch of each pair of switches is connected between the positive end of the power supply end equipment manager and the central tap of one transformer of each pair of transformers, and the other switch in each pair of switched is connected between the negative end of the power supply end equipment manager and the central tap of the other transformer of each pair of transformers. By means of the invention, the compatibility and the flexibility of the entire POE (Power Over Ethernet) system are improved, power loss on lines is reduced, meanwhile, the operation management by a user is simplified.

Description

technical field

[0001] The invention relates to Power Over Ethernet (POE, Power Over Ethernet) technology in the field of data communication, in particular to a power supply end device and a system and method for realizing power supply. Background technique

[0002] With the development of communication product technology, without any changes to the existing Ethernet wiring infrastructure, the power supply equipment (PSE, Power Sourcing Equipment) is some IP-based terminals (such as IP phones, wireless LAN access Point AP, network camera, etc.) while transmitting data signals, it can also use POE technology to provide DC power supply for such devices. These IP-based terminals do not need to install power equipment separately and connect power cables for this purpose, and are called powered end devices (PD, PowerDevice). More and more network devices have the POE function for powering these PDs, including routers and switches.

[0003] The Ethernet cable connected to the po...
