Maintain uptime at the access layer with a switch built for dense PoE deployments. The ExtremeSwitching 5420F-48P-4XE delivers 48 x 10/100/1000BASE-T PoE+ ports, giving you the port density needed for phones, cameras, wireless access points, and other powered endpoints without adding midspan injectors. Four unpopulated 10 Gb SFP+ uplink slots provide a clean path to aggregation and core connectivity, while the two stacking/SFPDD ports support resilient topologies and simpler expansion. MACsec capability adds a security layer for environments where traffic protection matters across the wired edge. This model is designed for infrastructure teams that want more than basic switching. The internal fixed PSU and fan design support a deployment profile suited to always-on access networks, and the unpopulated modular PSU slot leaves room for power architecture choices as requirements change. For organizations standardizing on secure, high-density PoE access, it offers the right mix of port count, uplink headroom, and enterprise features.
