    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: An antenna includes a feeding element and at least one non-feeding element. A vertical distance between each non-feeding element and the feeding element falls within a specified threshold, each non-feeding element includes a first conductor that is grounded, a regulator circuit, and a control switch disposed on the first conductor and configured to control the regulator circuit, where the regulator circuit is configured to regulate a current path length of the non-feeding element. The non-feeding element forms a reflector when the regulator circuit is enabled, or the non-feeding element forms a director when the regulator circuit is disabled. A design in which the reflector and the director are compatible is used such that a combination of one feeding element, M directors and N reflectors is implemented for the antenna to achieve a high directive gain and interference suppression capability.

    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: An antenna array and a wireless communications device are disclosed. The antenna array includes at least two directional antennas in different directions. Each directional antenna includes an antenna element, a reflector, a feed line coupled to the antenna element, and a switch for controlling the feed line. The antenna element is a microstrip dipole antenna element. The reflector is a parasitic microstrip antenna element. A length of the reflector is greater than a length the antenna element. Two ends of the reflector are bent toward the antenna element. A distance between midpoints of reflectors of any two directional antennas is less than a distance between midpoints of antenna elements thereof. Because the reflectors of the antenna array are located on an inner side of a pattern enclosed by the antenna elements of directional antennas, a size of the antenna array is small.

    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.
