PoE (Power over Ethernet) passthrough switches are a game-changer for network setups. These devices deliver both power and data through a single ethernet cable, making them perfect for powering IP cameras, wireless access points, and VoIP phones. This not only simplifies your cabling but also enhances overall network efficiency. So, how do they work? You connect the switch to a PoE-enabled power source, and it takes care of the rest. It receives power and data, then distributes both to the devices connected to it. This setup cuts down on the need for extra power cables, lowers installation costs, and offers great flexibility and scalability for your network. PoE passthrough switches are a smart, cost-effective solution for expanding your network.
