Title: POWERED METHOD AND POWERED DEVICE AUTOMATICALLY ADJUSTING POWER DEMAND LEVEL
Abstract:
Powered method and powered device automatically adjusting power demand level, the method comprising: detecting whether a power sourcing equipment (PSE) is supplying power for a powered device (PD) after a grading process, and obtaining a detection result; when the detection result is that the PSE is not supplying power for the PD, lowering the power level of the PD. The present invention makes progress in power grading of a power over ethernet (POE) system, achieves automatic adjustment of the power level according to the PSE power supply capability, and maximizes the PSE power supply capability, thus enabling more terminal devices to work and improving the use efficiency of the entire POE system.
