Ethernet power supply method, power supply device and power supply equipment

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. 本发明公开了种以太网供电方法、供电装置及供电设备，所述以太网供电方法应用于供电设备，所述供电设备包括HPOE端口，所述以太网供电方法包括：在所述HPOE端口接入PD设备并确定所述PD设备的类型；基于所述PD设备的类型，对所述PD设备供电；其中，所述供电设备能对至少两种类型的PD设备进行供电，所述至少两种类型的PD设备包括POE设备和HPOE设备。本发明提供的上述方法，解决现有技术中存在HPOE供电方式的兼容性差技术问题。
