If PI power management is disabled, when PSE power overload occurs, the PSE does not supply power
to new PDs.

If a PoE profile has been applied to a PI, remove the application before configuring the PI in PoE profile
view.
If a PI has been configured, remove the configuration before configuring the PI in PI view.
