PoE Configuration 343
After the PoE feature is enabled, perform the following configuration to enable
the PD compatibility detection function.
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.
c
Caution: If you adjust the PD disconnection detection mode when the device is
running, the connected PDs will be powered off. Therefore, be cautious when
doing so.
Configuring PoE
Over-Temperature
Protection on the Switch
If this function is enabled, the switch disables the PoE feature on all ports when its
internal temperature exceeds 65°C (149°F) for self-protection, and restores the
PoE feature settings on all its ports when the temperature drops below 60°C
(140°F).

Upgrading the PSE
Processing Software
Online
The online upgrading of PSE processing software can update the processing
software or repair the software if it is damaged. Before performing the following
configuration, download the PSE processing software to the Flash of the switch.
