Detecting PDs
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 if you enable the PSE
to detect nonstandard PDs.
To enable the PSE to detect nonstandard PDs:
Step Command Remarks
412. Enter system view. system-view N/A
413. Enable the PSE to detect
nonstandard PDs. By default, the PSE can detect
only standard PDs.

Configuring a PD disconnection detection mode
CAUTION:
If you change the PD disconnection detection mode while the device is running, the connected PDs are
powered off.
To detect the PD connection with a PSE, PoE provides two detection modes: AC detection and DC
detection. The AC detection mode uses less energy than the DC detection mode.
To configure a PD disconnection detection mode:
Step Command Remarks
414. Enter system view. system-view N/A
Optional. 415. Configure a PD disconnection
detection mode.
poe disconnect { ac | dc }
The default is AC.
