Configuring The Pd Compatibility Detection Function; Configuring A Pd Disconnection Detection Mode; Configuring Poe Over-Temperature Protection On The Switch - 3Com 4500 PWR 26-Port Configuration Manual

Configuring the PD Compatibility Detection Function

After the PD compatibility detection function is enabled, the switch can detect the PDs that do not
conform to the 802.3af standard and supply power to them.
After the PoE feature is enabled, perform the following configuration to enable the PD compatibility
detection function.
Follow these steps to configure the PD compatibility detection function:
To do...
Enter system view
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.
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 switch is running, the connected PDs will
be powered off. Therefore, be cautious to do 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).
Follow these steps to configure PoE over-temperature protection on the switch:
To do...
Enter system view
Enable PoE over-temperature
protection on the switch
Use the command...
system-view
poe legacy enable
Use the command...
system-view
poe disconnect { ac | dc }
Use the command...
