A 24-Port PoE Switch can greatly reduce the associated cost with smaller PoE installations in a home or business environment, while allowing you to expand your network to areas with no power lines or output. A 24-Port PoE switch will comply to either the IEEE 802.3af standard for PoE up to 15.4W per port or the latest IEEE 802.3at standard for PoE+ that is capable of up to 30W per port.
