Keep high-density edge networks powered, segmented, and ready for growth with the ExtremeSwitching 5420F 16port PoE+ Switch. This model combines 16 PoE+ ports with a 90 W PoE budget, giving you enough capacity for access points, phones, cameras, and other powered endpoints in demanding access-layer deployments. With 100 Mb/1 Gb/2.5 Gb support on the access side, it is designed for mixed-speed environments where newer endpoints need more than basic Gigabit connectivity. The switch also includes 2 stacking/SFPDD uplinks and 4 unpop 10G SFP+ slots, providing the uplink flexibility that enterprise networks expect when aggregation, redundancy, or future expansion matters. MACsec capability adds a security layer for organizations that need protected traffic across the access infrastructure. Internal fixed PSU fans and an unpopulated modular PSU slot reflect a design built for operational continuity and serviceability. Compared with smaller PoE switches, the 5420F gives infrastructure teams more port density, more uplink options, and more electrical headroom in a single access switch. That makes it a strong fit for campuses, branch aggregation, and enterprise closets where the cost of under-sizing is higher than the cost of buying the right platform once.
