POWERED DEVICE, POWER SOURCING EQUIPMENT DEVICE, POWER-OVER-ETHERNET NETWORK SYSTEM, AND METHODS THEREFORE

The present invention relates to Power-over-Ethernet (PoE) systems. The invention proposes to use a classification event to communicate from the PD (121) to the PSE (110, 910). A sensor (310, 410, 510a, 510b) may determine a sensor value, shut down the PoE connection, and reconnect so that the power...

Summary:The present invention relates to Power-over-Ethernet (PoE) systems. The invention proposes to use a classification event to communicate from the PD (121) to the PSE (110, 910). A sensor (310, 410, 510a, 510b) may determine a sensor value, shut down the PoE connection, and reconnect so that the power up cycle with the PSE (110, 910) will start. The sensor (310, 410, 510a, 510b) provides a PoE resistance related to a class 0, 3 where the class relates to the sensor value (e.g., class 0=presence detected; class 1=no presence detected). This procedure may be repeated (e.g. continuously, every minute or whenever the sensor value changes such that the PSE (110, 910) needs to be informed) and if needed multiple cycles can be used to increase the length of the message communicated.
