Connect dense 25GbE endpoint environments to higher-speed aggregation with 48 SFP28 interfaces and eight QSFP28 interfaces rated for 100GbE connectivity. The Extreme Networks 8522-48Y-8C-AC-F provides the port density needed where servers, storage nodes, or downstream network devices require numerous 25GbE optical or direct-attach connections while upstream paths require higher-bandwidth links. The 48 SFP28 ports provide a concentrated interface count for racks that need consistent 25GbE attachment capacity. Eight 100GbE QSFP28 ports provide separate high-speed connectivity for uplink, spine, aggregation, or inter-switch paths. This port combination helps retain 25GbE at the attachment layer while reserving 100GbE interfaces for traffic leaving the rack or connecting to the wider fabric. This ordering configuration includes an AC power supply and front-to-back fan airflow. Front-to-back airflow matters in equipment rows where switch cooling direction must match the rack cooling plan and neighboring systems. The distinguishing configuration details are the 48-port 25GbE SFP28 layout, eight 100GbE QSFP28 interfaces, included AC power, and F-B fan direction. Select it when those port types, interface counts, and airflow orientation match the intended rack design.
