    Abstract: A network device probes whether a first port of the network device is coupled to power sourcing equipment, and when probing that the first port is coupled to power sourcing equipment, maintain or change the first port to a powered state, and lock the first port as a power drawing port, or when probing that the first port is decoupled to power sourcing equipment, and the network device has a power supply for supplying power, change the first port to a powering state. In this way, the first port may adaptively serve as a power drawing port or a power sourcing port according to a coupled device such that manually distinguished a port during device interconnection is not necessary and a coupling error rate is reduced.

    Abstract: 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.

    Abstract: 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.

    Abstract: A wireless access point, a terminal device, and a method for waking up a terminal device by a wireless access point. The terminal device includes a primary radio frequency circuit and a wake-up radio (WUR) radio frequency circuit. The WUR radio frequency circuit only receives a radio signal and operates on a specified channel. If the WUR radio frequency circuit receives a wake-up frame on the specified channel and the terminal device is a to-be-woken-up terminal device, the WUR radio frequency circuit wakes up the primary radio frequency circuit. The wake-up frame includes an identifier of the to-be-woken-up terminal device. The primary radio frequency circuit operates on an operating channel of the primary radio frequency circuit after being woken up.

    Abstract: A sampling assembly and a sampling method are provided. A self-calibration unit controls a first switch to be turned on, to enable a first sampling signal to be input to a sampling unit. The sampling unit processes the first sampling signal to obtain a second sampling signal, and outputs the second sampling signal to the self-calibration unit. The self-calibration unit controls the first switch to be turned off, controls a second switch to be turned on, and outputs a first calibration signal to the sampling unit. The sampling unit processes the first calibration signal to obtain a second calibration signal, and outputs the second calibration signal to the self-calibration unit. The self-calibration unit determines an error signal based on the first calibration signal and the second calibration signal. The self-calibration unit obtains a calibrated third sampling signal based on the second sampling signal and the error signal.
