Abstract

The invention discloses an Ethernet power supply method, a power supply device and power supply equipment. The Ethernet power supply method is applied to the power supply equipment. The power supply equipment comprises an HPOE port. The Ethernet power supply method comprises the following steps of: accessing PD equipment at the HPOE port, and determining the type of the PD equipment; and, supplying power to the PD equipment based on the type of the PD equipment, wherein the power supply equipment can supply power to at least two types of PD equipment; and at least two types of PD equipment include POE equipment and HPOE equipment. By means of the method provided by the invention, the technical problem that the HPOE power supply type is poor in compatibility in the prior art can be solved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an Ethernet power supply method, a power supply device and power supply equipment. Background technique [0002] Twisted pair (twisted pair, TP) is the most commonly used transmission medium (commonly known as network cable) in integrated wiring engineering, and there are 4 pairs of 8 wires in it. Currently commonly used signal lines 1, 2, 3, and 6 are used for ordinary data transmission; the remaining 4, 5, 7, and 8 pairs are reserved lines for future consideration. [0003] The currently prevailing standards for Power over Ethernet (POE) mainly include IEEE 802.3af (POE) and IEEE 802.3at (POE+). The difference between the two is that the ports provide 15.4W and 30W output power respectively. POE is divided into two components, PSE and PD, power sourcing equipment (Power Sourcing Equipment, PSE) and powered equipment (Powered Device, PD). The PSE is generally located on th...
