Fast PoE and Perpetual PoE

Fast PoE minimizes the PoE controller recovery time in case of a power failure. With Fast PoE, the PoE controller initializes the moment the switch powers on, which results in a faster recovery period.

Perpetual PoE provides uninterrupted power to all connected devices during a switch reboot.
