Systems and methods are provided for an auto-negotiation mode of operation that allows power source equipment (PSE) and a powered device (PD) to negotiate power transfer and/or data communication without the use of conventional classification pulses. The auto-negotiation mode of operation provides for a universal negotiation of information between the PSE and PD regardless of the specific capabilities of each. The information can be used to configure the power to be applied to the communication link and/or data communication over the communication link. |
