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: A system includes a processor and a memory. The processor locates a first memory chip that is faulty in a memory. After the first memory chip is isolated or replaced, the processor may reset the first memory chip when other memory chips in the memory are maintained to work normally. When a fault occurs in a memory chip in the memory, after the first memory chip that is faulty is isolated or replaced, the processor may independently reset the first memory chip without affecting the other memory chips in the memory. Resetting the first memory chip enables the first memory chip to restore to normal. A memory chip that can be normally used is used as a redundant memory chip or may continue to be used.

Abstract: This disclosure discloses a power supply method and a power supply device, and pertains to the field of power supply technologies. The method includes: supplying, by a power supply device, power to a load through a power supply port, where the power supply port is connected to a power receiving port of the load by using a power supply cable; and communicating, by the power supply device, with the load through a communications port, to manage a behavior of obtaining power by the load from the power supply device, where the communications port is connected to a communications port of the load by using a communications cable. In this disclosure, the power supply device is a power supply of the load and a controller of the load.
