Gigabit managed 16+2+2 gigabit optical ports
PoE technology (Power over Ethernet) refers to the technology that provides power over Ethernet. It means that while transmitting data signals to some IP-based terminals (such as IP phones, wireless access points, network cameras, etc.), it also provides DC power to these devices. The devices that receive DC power are called powered devices.
