Abstract

The invention discloses an Ethernet power supply unit and network. The Ethernet power supply unit comprises an built-in power supply module, a switch master control module, a power conversion module and an RJ45 interface module, wherein the power conversion module is connected with the built-in power supply module and the switch master control module; the built-in power supply module converts the external 220V AC input into DC output, and supplies power for the switch master controlling module through the power conversion module; the switch master controlling module is connected with the RJ45 interface module to transmit a data signal to the RJ45 interface module; the power conversion module is connected with the RJ45 interface module to supply power for the RJ45 interface module; and an Ethernet network can be formed by connecting more than one Ethernet power supply units. The realizing mode in the Ethernet power supply unit and network can be use to simplify the design of the power supply circuit, on the premise of richening the power supply modes of the switch, the POE (power over Ethernet) network power supply function can be realized, and the elastic range of the external power supply input is increased.

Description

technical field [0001] The invention relates to an Ethernet power supply device, in particular to a power supply device applied to a computer communication Ethernet power supply device such as a switch. Background technique [0002] POE (Power Over Ethernet) refers to the transmission of data signals for some network terminal equipment without any changes to the existing Ethernet Category 5 twisted pair (Cat.5) wiring infrastructure. At the same time, it can also provide DC power supply technology for such devices. POE technology can guarantee the normal operation of the existing network while ensuring the safety of the existing structured wiring. A complete POE system includes two parts: power supply equipment (PSE, Power Sourcing Equipment) and power receiving equipment (PD, Power Device) . The PSE device is a device that supplies power to Ethernet client devices, and is also the manager of the entire POE Power over Ethernet process. The PD device is the PSE load that r...
