Novel system and methodology for adjusting a current limit threshold in a Power over Ethernet (PoE) system in accordance with requirements of a Powered Device (PD). A system for supplying power to a PD over a communications link has a requirement determining circuit for determining a PD's requirement, and a control circuit for setting a parameter restricting an output signal of the PSE in accordance with the determined PD's requirement. The control circuit may set a current limit threshold of the PSE and/or the PD in accordance with the determined PD's requirement, such as a power requirement.

Adjusting current limit thresholds based on power requirement of powered device in system for providing power over communication link

System and methodology for providing classification of a load in a power supply system for providing power over a communication link. The power supply system has a classification engine for probing the load to determine a characteristic of the load. The classification engine supplies the load with multiple classification signals to determine multiple response signals presented by the load in response to the respective classification signals.
