1-5Configuring the PD Compatibility Detection FunctionAfter the PD compatibility detection function is enabled, the switch can detect the PDs that do notconform to the 802.3af standard and supply power to them.After the PoE feature is enabled, perform the following configuration to enable the PD compatibilitydetection function.Follow these steps to configure the PD compatibility detection function:To do… Use the command… RemarksEnter system view system-view —Enable the PD compatibilitydetection function poe legacy enable RequiredDisabled by default.Configuring a PD Disconnection Detection ModeTo detect the PD connection with PSE, PoE provides two detection modes: AC detection and DCdetection. The AC detection mode is energy saving relative to the DC detection mode.Follow these steps to configure a PD disconnection detection modeTo do… Use the command… RemarksEnter system view system-view —Configure a PD disconnectiondetection mode poe disconnect { ac | dc }OptionalThe default PD disconnectiondetection mode is AC.If you adjust the PD disconnection detection mode when the switch is running, the connected PDs willbe powered off. Therefore, be cautious to do so.Configuring PoE Over-Temperature Protection on the SwitchIf this function is enabled, the switch disables the PoE feature on all ports when its internal temperatureexceeds 65°C (149°F) for self-protection, and restores the PoE feature settings on all its ports when thetemperature drops below 60°C (140°F).Follow these steps to configure PoE over-temperature protection on the switch:To do… Use the command… RemarksEnter system view system-view —Enable PoE over-temperatureprotection on the switchpoe temperature-protectionenableOptionalEnabled by default.
