Abstract
A PoE system PSE, constituted of: a power source input; a classification functionality arranged to determine the class of a PD; a memory arranged to store thereon the determined class; a timing functionality arranged to output the length of a power interruption to the power source input; and a control circuitry; wherein, responsive to an indication of the timing functionality that the power interruption length is greater than a predetermined time value, the control circuitry is arranged to initiate the class determination of the classification functionality, and wherein, responsive to an indication of the timing functionality that the power interruption length is not greater than the predetermined time value, the control circuitry is arranged to: supply power from the power source input to the PD responsive to the stored determined class; and not initiate the class determination of the classification functionality prior to the power supplying.
