Switches connected in series for PoE
In a daisy-chain topology, PoE switches are connected in series, one after another. A PoE switch is a network switch that utilizes PoE technology to transmit power and data over the same Ethernet cable to powered devices such as IP cameras, wireless access points, and VoIP phones, simplifying installation and reducing maintenance costs. Each switch is linked to the next in this configuration, forming a chain. This eliminates the need for separate power adapters, reducing cable clutter and. Power over Ethernet (PoE) is a newer way to provide DC power while also accommodating data through an Ethernet cable.
