Keep wired access, phones, cameras, and wireless endpoints online on a switch built for demanding campus edge deployments. The Extreme Networks 5420M-48W-4YE combines 48 10/100/1000BASE-T ports with 802.3bt PoE support up to 90 W per port, giving you the headroom to power higher-draw devices without adding midspan clutter. This model is designed for environments where uptime and expansion matter. Two stacking/SFPDD positions and four unpopulated 10/25G SFP28 uplink slots provide a clear path for aggregation and future bandwidth growth. MACsec capability adds a security layer for sensitive traffic, while the included fan module and dual unpopulated modular PSU slots support a more resilient hardware profile than entry-level access switches. For teams standardizing on a premium access layer, this switch offers the density, power budget, and uplink options needed to support modern campus refreshes. It is a strong fit when you need to consolidate endpoints, preserve rack space, and avoid replacing access hardware again as PoE demands increase.
