TL/DR: A PoE switch delivers power and data over Ethernet cables, enabling devices like IP cameras and wireless access points to operate without separate power sources, simplifying installation and enhancing scalability.
Definition:
A PoE (Power over Ethernet) switch is a network switch that provides power and data to connected devices through Ethernet cables. It is commonly used to power devices like IP cameras, wireless access points, and VoIP phones, simplifying setup by eliminating the need for separate power sources.
How It Works:
A PoE switch integrates power delivery into its Ethernet ports. When a compatible device is connected, the switch supplies electrical power alongside data over the Ethernet cable. It automatically detects if the connected device supports PoE to ensure safe and efficient power delivery.
