Abstract

A power over Ethernet method includes: performing, by power sourcing equipment, a plurality of detections by using an Ethernet port, connected to an intermediate device, of the power sourcing equipment, where a quantity of detections performed by the power sourcing equipment is equal to a quantity of power supply ports of the intermediate device; and if at least one detection result of the plurality of detections is effective, sending, by the power sourcing equipment, a power supply indication to the intermediate device, and supplying power to the connection port. In this way, the power sourcing equipment can supply power across the intermediate device to a powered device connected to the intermediate device, and a power loss caused by voltage conversion is avoided.
