1-7This mode deletes the PSE processing software and reloads it. When the PSE processing software isdamaged (in this case, you can execute none of PoE commands successfully), you can upgrade thePSE software processing software in full mode to restore the PSE function.Online PSE processing software upgrade may be unexpectedly interrupted (for example, an errorresults in device reboot). If you fail to upgrade the PSE processing software in full mode after reboot,you can power off the device and restart it before upgrading it again. After upgrade, restart the devicemanually to make the original PoE configurations take effect.Follow these steps to upgrade the PSE processing software online:To do… Use the command… RemarksEnter system view system-view —Upgrade the PSE processingsoftware onlinepoe update { full | refresh }filename pse pse-id OptionalConfiguring 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 mode:To do… Use the command… RemarksEnter system view system-view —Configure a PD disconnectiondetection mode poe disconnect { ac | dc }OptionalThe default PD disconnectiondetection mode varies withdevices.If you adjust the PD disconnection detection mode when the device is running, the connected PDs willbe powered off. Therefore, be cautious to do so.Enabling the PSE to Detect Nonstandard PDsThere are standard PDs and nonstandard PDs. Usually, the PSE can detect only standard PDs andsupply power to them. The PSE can detect nonstandard PDs and supply power to them only after thePSE is enabled to detect nonstandard PDs.Follow these steps to enable the PSE to detect nonstandard PDs:To do… Use the command… RemarksEnter system view system-view —Enable the PSE to detectnonstandard PDs poe legacy enable pse pse-id OptionalDisabled by default.
