    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 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 sourcing equipment (PSE) chip controls a powering channel of the PSE chip according to a value stored in a first register; the PSE chip changes, in response to a second instruction, the value stored in the first register into a calculated value, where the second instruction includes a second slave address and a second data byte, the second slave address is a virtual address of a virtual powering group, and the calculated value is a result obtained by calculation according to the second data byte and a channel indication value that is of the virtual powering group and stored in the PSE chip. Information indicating whether a powering channel is added to a virtual powering group is stored in a PSE chip, so that powering channels added to a virtual powering group can be controlled at a time.

    Abstract translation: 电源设备（PSE）芯片根据存储在第一寄存器中的值来控制PSE芯片的供电通道; PSE芯片响应于第二指令将存储在第一寄存器中的值改变为计算值，其中第二指令包括第二从地址和第二数据字节，第二从地址是虚拟地址 计算值是通过根据第二数据字节的计算获得的结果和虚拟供电组的信道指示值，并存储在PSE芯片中。 指示是否将加电通道添加到虚拟供电组的信息存储在PSE芯片中，从而可以一次控制添加到虚拟供电组的通道。

    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: 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.
