Extreme Networks ExtremeSwitching 5420M 24-Port PoE++ Switch

The Extreme Networks 5420M-24W-4YE is a 24 port Gigabit Ethernet switch that brings robust PoE++ power and advanced Layer 3 control to edge and aggregation layers alike. It is a solid choice for campus wiring closets, branch offices, or any site that needs to support dense groups of powered devices while keeping management simple and consistent.

Every copper port can deliver up to 60 W, and the overall 1440 W budget lets the switch run Wi-Fi access points, PTZ security cameras, VoIP phones, or digital signage without separate power injectors. Four SFP28 slots accept 1, 10, or 25 Gigabit optics, giving you flexible uplink speeds, while two SFP-DD ports let you stack as many as eight units. When fully stacked the solution offers an aggregate bandwidth of 328 Gbps, so growing networks can add capacity without redesigning the topology.

Network teams will appreciate the 64K MAC address table and the Layer 3 feature set, which together support larger VLAN counts, routing at the edge, and clear traffic segmentation. MACsec encryption protects sensitive data on links to access points or other switches, and administrators can handle day-to-day tasks through a familiar CLI or remote management tools. The rack-mountable enclosure fits standard 19 inch racks, making installation straightforward in existing cabinets or server rooms.
