Before configuring PoE, make sure the PoE power supply and PSE are operating properly. Otherwise,
either you cannot configure PoE or the PoE configuration does not take effect.
If the PoE power supply is turned off while a device is starting up, the PoE configuration in the PoE profile
might become invalid.

Enabling PoE
Enabling PoE for a PSE
If PoE is not enabled for a PSE, the system does not supply power or reserve power for the PSE.
You can enable PoE of a PSE if the PSE will not result in PoE power overload. Otherwise, whether you can
enable PoE of the PSE depends on whether the PSE is enabled with the PoE power management function.
For more information about PSE power management, see "Configuring PSE power management."
