THERNET ONFIGURATION
When using the PWR switches to supply power to remote PDs, the PDs need
■
not have any external power supply.
If a remote PD has an external power supply, the PWR switches and the
■
external power supply will be redundant with each other for the PD.
Only the electrical ports of the PWR switches support the PoE feature.
■
The PWR switches can automatically detect any device that needs remote power
supply through the port to which it connects and feeds power to this device.
You can use the command line to enable/disable the PoE feature of a port, set the
power supply priority, maximum output power, and compatibility detect function
of a port.
PoE configuration tasks are listed in the following table.
