Power Over Ethernet is not only used when online. It is always used when the network device is connected and needs power.

PoE technology allows DC power to be provided to IP-based terminal devices while transmitting data through Ethernet cables. This power supply method is continuous. You can get power as long as the device is connected and follows the PoE standard.



Specifically, PoE switches can be used as ordinary switches when the power supply function is not required. Power Over Ethernet can maintain its data transmission function. When connected devices use PoE and need power, the PoE switch sends power through the network cable.

This power supply and data transmission happen at the same time. PoE is used when a network device is connected. It also works if the device needs power.
