PoE uses a DC voltage injected through “phantom power” on the same wire pairs or spare pairs, depending on the mode (A/B/4-pair). Ethernet signaling is AC-based and differential, so

By default, all switch ports are in PoE mode auto, which means that if the interface detects that PD is connected, it automatically starts providing power. This can be checked using the show power inline
