Build a stable access layer with the Extreme Networks 4220-48T-4X. This switch delivers 48 10/100/1000Base-T ports for endpoint connectivity and 4 1G/10G SFP+ ports for uplink or aggregation paths, giving network teams the port density and uplink flexibility needed in wired campus environments. Stackable design helps simplify growth. Instead of replacing a switch when port demand rises, teams can plan for expansion within a consistent platform, which reduces operational friction and keeps the access layer easier to standardize. The included fans and fixed AC power supply support a deployment model that is straightforward to rack, power, and maintain. This model is a practical fit for organizations that want a managed switch with enough copper density for user access, enough uplink headroom for aggregation, and a form factor that supports future scaling without overbuying at the edge. It is the kind of switch that earns its place in a production network by staying predictable, serviceable, and easy to slot into a larger switching strategy.
