Keep dense wireless and wired edge environments moving with the Extreme Networks 4120-48MW-4Y. This 48-port MultiGig switch supports 10M/100M/1G/2.5GBase-T on every access port, with up to 90 W PoE per port to power Wi‑Fi 6/6E access points, cameras, phones, and other high-demand endpoints without external injectors. Designed for aggregation and campus access, it adds 4 x 25G SFP28 uplinks and 2 x 100G QSFP28 universal/stack ports to remove uplink congestion and support growth without a forklift refresh. Stackable architecture simplifies expansion and operational consistency across closets, while fixed fans and an internal AC PSU keep the platform straightforward to deploy. For teams standardizing on higher-power edge switching, this model delivers the port density, uplink headroom, and power envelope needed to support modern access layers with fewer compromises than entry-level PoE switches.
