Handle high-density edge connectivity with a switch designed for access layers that carry both power and traffic at scale. The ExtremeSwitching 5420F 48P-4XL provides 48 10/100/1000Base-T PoE+ ports for phones, cameras, wireless access points, and other powered endpoints, making it well suited to office floors, classrooms, and campus wiring closets. Its fixed architecture includes stacking support for simplified expansion and 4 unpopulated 10G SFP+ uplink slots for higher-speed aggregation when the network design calls for it. MACsec capability adds a security layer for environments that need protected traffic across trusted infrastructure segments. The internal fixed PSU and fan design supports a deployment model focused on consistent operation rather than modular complexity. This switch is a strong fit when port density, secure uplinks, and operational consistency matter more than a low-cost commodity access device. It gives infrastructure teams a practical way to standardize PoE access switching across multiple closets while preserving headroom for future uplink and stacking requirements.
