    Abstract: 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.

    Abstract translation: 一种以太网供电方法，其中电源设备（PSE）检测并确定以太网双绞线的第一组电缆对和第二组电缆对连接到有效的供电设备（PD），PSE接收链路 来自PD的层发现协议数据单元（LLDPDU），其中LLDPDU包括用于通知包括在PD中的PD负载量的负载量类型长度值（TLV），以及当PD从第一个 电缆组和第二组电缆对，PD包括两个PD接口，PD包括两个PD负载，PSE使用第一组电缆对以第一电源为PD供电，并提供电源 使用第二组电缆对以第二功率到达PD。
