  • Device and method for detecting powered devices connected to a power source equipment in a power over ethernet system
    Patent number: 10447488
    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.
    Type: Grant

  • Inspection device and method for powered devices in a power over Ethernet system
    Patent number: 10142116
    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.
