Detecting PDs
Enabling the PSE to detect nonstandard PDs
Two types of PDs are available: standard PDs and nonstandard PDs. The PSE can only detect standard
PDs and supply power to them. The PSE can only detect nonstandard PDs and supply power to them after
the PSE is enabled to detect nonstandard PDs.
To enable the PSE to detect nonstandard PDs:
To do…
Use the command… Remarks
1. Enter system view.

2. Enable the PSE to detect
nonstandard PDs.
poe legacy enable pse pse-id
Required.
By default, the PSE can detect
standard PDs rather than non
standard PDs.
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.
To configure a PD disconnection detection mode:
To do…
Use the command… Remarks

2. Configure a PD disconnection
detection mode.
poe disconnect { ac | dc }

CAUTION:
If you change the PD disconnection detection mode when the device is running, the connected PDs will
be powered off. Be cautious to do so.
