Abstract: A power source equipment for power over Ethernet system comprising a plurality of power source devices, each configured to determine, after having determined the power source device is connected by an external device without a powered device (PD) signature, whether another power source device is connected by a power device with a PD signature. If the determination is positive, the two power source devices are determined having been connected by the same PD and power is supplied to the PD by the two power source devices.

Abstract: The present invention relates to device and method for detecting powered devices connected to a power source equipment in a Power over Ethernet system that provides multiple signal/power channels. A series of inspection signals including one discriminative signal is applied to the respective channels and response signals to the discriminative signal and other detection signals are compared in order to determine whether multiple channels are connected to one single powered device.

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.

Abstract: An inspection device to determine whether a device connected to a Power over Ethernet system is suited for being powered, is configured to apply an inspection signal to the device and to measure a response signal thereto. The inspection signal includes a first, second, third and fourth voltage, wherein the first voltage and the third voltage are substantial the same and the second voltage and the fourth voltages are substantial the same, and an application period for applying the fourth voltage is sum of the application period for the second voltage and an extension period. The inspection device determines that the device is not suitable for being powered if a response signal exceeds predetermined ranges. A method to perform these inspections is also disclosed.
