Abstract
A power source equipment for Power over Ethernet system provides an adjustment mechanism for the maximum allowable power of communication port connected to the power source, whereby when a device requests to join as a powered device but a maximum allowable power of a corresponding class is greater than the difference of the total supplied power and the sum of maximum allowable power designated to the then connected powered devices, the maximum allowable power of the respective powered devices may be adjusted, to generate sufficient allowable power for the requesting device. A power supplying method using the adjustment mechanism is also disclosed.
