Configuring a PD Disconnection Detection Mode

To detect the PD connection with PSE, PoE provides two detection modes: AC detection and DC
detection. 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...
Enter system view
Configure a PD disconnection
detection mode
If you adjust the PD disconnection detection mode when the device is running, the connected PDs will
be powered off. Therefore, be cautious to do so.

Enabling the PSE to Detect Nonstandard PDs

There are standard PDs and nonstandard PDs. Usually, the PSE can detect only standard PDs and
supply power to them. The PSE can detect nonstandard PDs and supply power to them only after the
PSE is enabled to detect nonstandard PDs.
Follow these steps to enable the PSE to detect nonstandard PDs:
To do...
Enter system view
Enable the PSE to detect
nonstandard PDs
Use the command...
system-view
poe update { full | refresh }
filename pse pse-id
Use the command...
system-view
poe disconnect { ac | dc }
Use the command...
system-view
