  • Power over Ethernet (PoE) Power Supplying Method and Apparatus
    Publication number: 20230344661
    Abstract: A power over Ethernet (PoE) power supplying method where power sourcing equipment (PSE) and a powered device exchange link layer discovery protocol data units (LLDPDUs). Each of the LLDPDUs includes two power values. Each of the power values indicates requested or allocated power for one of two sets of cable pairs of the Ethernet twisted pair connecting the PSE and the powered device. Accordingly, the supplied powers to the powered device at sets of cable pairs are independent from each other.
    Type: Application

  • Power over ethernet (PoE) power supplying method and apparatus
    Patent number: 10057074
    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.
