摘要
A method of allocating power to ports in an Ethernet switch, including: (1) determining the available capacity of a power pool used to supply the ports, (2) assigning a configuration power to each of the ports, (3) selecting a port to be enabled, (4) determining whether the available capacity of the power pool exceeds the configuration power assigned to the selected port, and, if the available capacity of the power pool exceeds the configuration power assigned to the selected port, then (4) subtracting the configuration power assigned to the selected port from the available capacity of the power pool, (5) enabling and powering the selected port and simultaneously detecting whether the selected port is connected to a powered device, and (6) adding the configuration power assigned to the selected port to the available capacity of the power pool if the port is not connected to a powered device.
