Abstract: This application discloses a power supply management system, and a power supply management method and apparatus applied to the system. The system includes a power sourcing equipment, a powered device, and a power supply line. The power sourcing equipment sends a second voltage to the powered device to determine a first voltage. The first voltage is a maximum power supply voltage agreed on by the power sourcing equipment and the powered device. The power sourcing equipment supplies power to the powered device based on the first voltage. In this application, the power sourcing equipment supplies power to the powered device based on the maximum power supply voltage that can be supported by the powered device, so that a loss on the power supply line is reduced.

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.

Abstract: Embodiments provide a content sharing method and system. A source terminal cloud server receives a content sending command sent by a source terminal, where the content sending command carries an address of a destination terminal cloud server. The source terminal cloud server sends a connection request to the destination terminal cloud server according to the address of the destination terminal cloud server, where the connection request is used to request to establish a connection to the destination terminal cloud server. The source terminal cloud server sends shared content to the destination terminal cloud server after the connection is established. After the shared content is transferred between the cloud servers, terminals respectively log in to their respective cloud servers.
