Extreme Networks 5420M 16-Port PoE+ Switch with 90W & 32 Ports

The Extreme Networks 5420M-16MW-32P-4YE is a switch that brings reliable power and high-speed connectivity to an enterprise edge or wiring closet. It combines data switching with Power over Ethernet, so a single piece of equipment can run phones, access points, cameras, and other networked hardware without separate power adapters.

Sixteen ports support PoE++ and can deliver up to 90 watts each. These ports easily handle high-draw devices such as Wi-Fi 6 access points, motorized PTZ cameras, or LED lighting panels. Another thirty-two ports provide standard PoE+ with up to 30 watts per port, which is well suited for desk phones, sensors, and badge readers. With this mix, one switch can serve an entire floor of diverse endpoints while keeping cable runs tidy.

Performance is more than enough for busy traffic patterns. The switch offers 424 Gbps of aggregate bandwidth and forwards up to 315.5 million packets per second, so it keeps pace during large file transfers, voice calls, and video streams. A 64,000-entry MAC address table supports a dense device population without slowdowns.

Four SFP28 uplink ports give network architects flexible options for high-speed fiber backhaul to the core. Two power-supply bays remain open, allowing a team to add redundancy for extra resilience whenever it fits the build-out schedule.

Security and management are built in. MACsec encryption protects traffic on every port, and a familiar CLI lets administrators fold the switch into existing scripts or orchestration tools. At only 1.7 inches high, the chassis slides neatly into a standard rack, making it an easy fit in crowded equipment rooms.

Whether you are expanding a campus network, outfitting a new office floor, or consolidating edge infrastructure, this model offers the mix of power, capacity, and security that modern workloads expect.
