Deliver reliable power and uplink capacity where access-layer density matters. The Extreme Networks 4220-12P-4X combines 12 Gigabit PoE+ ports with a 124 W PoE budget, giving you enough headroom for phones, cameras, and wireless access points without adding separate injectors. Four 1G/10G SFP+ ports provide flexible uplink options for aggregation or downstream switching, helping preserve bandwidth as the edge grows. This switch is built for practical enterprise deployment. Its stackable design simplifies expansion, while the fixed AC power supply keeps the footprint straightforward for branch closets and small wiring rooms. Silent mode operation up to 35 C makes it easier to place near work areas where fan noise matters. For teams standardizing on a compact access switch with real uplink flexibility, the 4220-12P-4X offers the right balance of power delivery, port mix, and deployment simplicity.
