Standard PDs are PDs in compliance withIEEE 802.3af. Usually, a PSE can detect only standard PDs and supply power to them. A PSEcan detect non-standard PDs and supply power to them only when the PSE is enabled to detectnon-standard PDs.Follow these steps to enable a PSE to detect non-standard PDs:To do… Use the command… RemarksEnter system view system-view —Enable a PSE to detectnon-standard PDs poe legacy enable pse pse-idRequiredBy default, a PSE can detectstandard PDs rather thannon-standard PDs.Configuring a PD Disconnection Detection ModeTo detect the PD connection with a PSE, PoE provides two detection modes: AC detection andDC detection. The AC detection mode is energy saving relative to the DC detection mode.Follow these steps to configure a PD disconnection detection mode:
