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 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 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.

Abstract: A power over Ethernet (PoE) power supplying method where power sourcing equipment (PSE) and a powered device exchange link layer discovery protocol data units (LLDPDUs). Each of the LLDPDUs includes two power values. Each of the power values indicates requested or allocated power for one of two sets of cable pairs of the Ethernet twisted pair connecting the PSE and the powered device. Accordingly, the supplied powers to the powered device at sets of cable pairs are independent from each other.

Abstract: The application pertains to a method for an Ethernet power sourcing equipment to provide electric power to one or more Ethernet powered devices. A controlling apparatus determines a power supply mode of the Ethernet power sourcing equipment, and determines high-power Ethernet powered device(s) and low-power Ethernet powered device(s) among the Ethernet powered devices. The controlling apparatus sets a power supply priority for each of the Ethernet powered devices. In one power supply mode, the power supply priority of a high-power Ethernet powered device is same as or lower than the lowest priority of the low-power Ethernet powered device(s). When a new Ethernet powered device is connected to the Ethernet power sourcing equipment, the controlling apparatus determines whether to supply electric power to the new Ethernet powered device according to its power supply priority.
