Keep access-layer services online with the HPE 5520 48G PoE+ 4SFP+ HI switch. It combines 48 PoE+ ports with 4 SFP+ uplinks to support high-density endpoint deployments while preserving clean fiber uplink paths to distribution or core layers. The high-availability design is built for environments where switch downtime affects users, phones, cameras, and wireless coverage. This model fits enterprise access networks that need more than basic connectivity. PoE+ support reduces the need for local power at the edge, while the SFP+ uplinks provide higher-speed aggregation options for bandwidth-sensitive traffic. That makes it a strong fit for modern office floors, campus closets, and converged network segments where access switching must carry both scale and uptime expectations. Choose this switch when you need dependable port density, uplink flexibility, and a platform suited to long-term infrastructure planning. It is the kind of access switch that justifies its place in a production network by reducing edge complexity and supporting critical devices without compromise.
