Support phones, cameras, wireless access points, and other powered endpoints with a switch designed for dense access-layer builds. The Extreme 4220-48P-4X delivers 48 10/100/1000BaseT PoE ports, each rated at 30 W, backed by a 370 W PoE budget to keep more devices powered from the rack. Four 1G/10G SFP+ ports provide flexible uplink options for aggregation or higher-speed backbone connections, while the stackable design helps teams expand capacity without redesigning the closet. Included fans and a fixed AC PSU simplify deployment in environments where predictable hardware behavior matters. This model is a strong fit when you need more than a basic access switch: enough PoE headroom for endpoint-heavy floors, enough uplink speed for traffic growth, and a platform that can be integrated into a larger Extreme switching environment. It is the kind of switch selected when uptime, port density, and power delivery justify the investment.
