Perpetual PoE
Perpetual PoE allows the switch to supply power to PDs during reboot. The
switch stores the power parameters for ports supplying PoE power when the
running configuration is saved. If Perpetual PoE was enabled when the
configuration was saved, power is not interrupted on PoE enabled ports
during reboot. During or after the reboot cycle completes, the switch may
power down or power up ports based upon the supplied power.
It is not possible to configure Perpetual PoE on individual ports.
Perpetual PoE is only available on the N1100EP-ON, N2200PX-ON, N3200P-
ON, N3200PX-ON, and N3200PXE-ON Series switches.
Fast PoE
Fast PoE allows the switch to supply power to powered devices (PDs) prior to
the switch firmware initializing the PoE ports during a power up event. The
switch stores the power parameters for ports supplying PoE power when the
running configuration is saved. Fast PoE is enabled by default and cannot be
disabled. During or after the reboot cycle completes, the switch may power
down or power up ports based upon the supplied power.
