Patent number: 11329837Abstract: A network device includes a power system, a processor, a power sourcing equipment PSE chip coupled to a first forward power supply port, and a first powered device PD chip coupled to a first reverse power receiving port. A first powered device is connected to the first forward power supply port and the first reverse power receiving port. When detecting that a power failure occurs on the network device, the processor instructs the first PD chip to draw power from the first powered device; the first PD chip draws the power from the first powered device through the first reverse power receiving port, and supplies the obtained power to the power system. Therefore, when a power failure occurs, the network device can continue to obtain power and work properly when the power failure occurs.Type: GrantFiled: April 22, 2019Date of Patent: May 10, 2022Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Shiyong Fu, Yan Zhuang, Jincan Cao, Fuguang Huang, Xueqi Chen, Rui Hua

Patent number: 11265179Abstract: A power supply management method performed by power sourcing equipment, includes receiving a power-on request from a level-1 powered device, where the power-on request includes a port identifier of a level-2 power supply port that is detected to be valid in the level-1 powered device, determining, based on the power-on request and an outputtable power of the power sourcing equipment, a level-2 power supply port that is allowed to be powered on in the level-1 powered device, and sending a power-on instruction to the level-1 powered device, where the power-on instruction includes a port identifier of the level-2 power supply port that is allowed to be powered on in the level-1 powered device. The power sourcing equipment uses the level-1 powered device and a level-2 powered device connected to the level-1 powered device as a whole, and centrally performs power supply control and power management.Type: GrantFiled: November 25, 2019Date of Patent: March 1, 2022Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Yan Zhuang, Shiyong Fu, Jincan Cao, Fuguang Huang, Xueqi Chen, Rui Hua

Patent number: 11183838Abstract: Power sourcing equipment for power over Ethernet (PoE) includes a power supply control circuit, an Ethernet port, and a surge protection circuit. The surge protection circuit includes a first circuit, a second circuit, and a common discharge circuit. The first circuit is connected to a power supply pin group of the Ethernet port, the power supply control circuit, and the common discharge circuit. The second circuit is connected to a non-power supply pin group of the Ethernet port and the common discharge circuit. The first circuit transmits, to the common discharge circuit, a first surge that is input from the power supply pin group. The second circuit transmits, to the common discharge circuit, a second surge that is input from the non-power supply pin group. The common discharge circuit discharges the first surge and the second surge to ground.Type: GrantFiled: June 6, 2019Date of Patent: November 23, 2021Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Shiyong Fu, Yan Zhuang, Qi Dong, Xiangen Xu, Xueqi Chen, Yu Ding

Patent number: 10951425Abstract: 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.Type: GrantFiled: April 1, 2019Date of Patent: March 16, 2021Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Yan Zhuang, Shiyong Fu, Jincan Cao, Fuguang Huang, Xueqi Chen, Rui Hua
