Keep wired access layers moving with the ExtremeSwitching 5420M-48T-4YE. This 48-port managed switch delivers 10/100/1000BASE-T connectivity for user, device, and edge aggregation traffic, while 4 unpopulated 10/25G SFP28 uplinks provide room for higher-speed upstream design. MACsec capability adds a security layer for environments that need protected traffic paths across the campus or distribution edge. Designed for infrastructure teams that value service continuity, the 5420M includes a fan module and two unpopulated modular PSU slots, giving you a chassis that is ready for resilient deployment planning. Stacking support helps simplify scale-out operations, while Layer 3 capability supports routed segmentation where access and aggregation functions converge. This model fits organizations that need more than a basic access switch. It is a practical choice for enterprise closets, branch aggregation, and secure edge deployments where port density, upgrade headroom, and operational control justify the investment.
