PoE Powered Device (PD)
Select compact switch models can work as PoE Powered Device (PD) and be powered by upstream PoE switches.
When AC power is connected and functioning correctly, it is preferred over PoE power. The PoE power can function as a backup to the AC power source or be used as the sole power source for the switch.
