Power over ethernet (PoE) power supplying method and apparatus
A power over Ethernet method where power sourcing equipment (PSE) detects and determines that a first set of cable pairs and a second set of cable pairs of an Ethernet twisted pair are connected to a valid powered device (PD), the PSE receives a link layer discovery protocol data unit (LLDPDU) from the PD, where the LLDPDU includes a load quantity type-length-value (TLV) used to notify a quantity of PD loads included in the PD, and when the PD receives power from both the first set of cable pairs and the second set of cable pairs, and the PD includes two PD interfaces, and the PD includes two PD loads, the PSE supplies power to the PD at a first power using the first set of cable pairs, and supplies power to the PD at a second power using the second set of cable pairs.
