description Disclosed is a power control method applicable to a power over Ethernet system, which includes: when it is determined that there is a target powered device connected to the power over Ethernet system, calculating a sum of actual power of all powered devices currently powered on to obtain a total required power; and determining whether the total required power exceeds a preset second threshold power threshold, if yes, powering off a powered device that is currently powered on according to priorities corresponding to port numbers of all the powered devices that are currently powered on until the total required power is less than the second power threshold; if not, determining whether to power on the target powered device according to a preset first power threshold, wherein the second power threshold is greater than the first power threshold.
