Consolidate high-density 10GbE copper server, storage, and appliance connections on 48 10GBASE-T interfaces, then hand traffic to six 100GbE uplinks. The 8522 platform fits aggregation and top-of-rack roles where copper endpoints must converge on higher-speed fabric links. Its fixed port layout concentrates access and uplink capacity in one rack-mounted switching system. This media combination suits environments retaining RJ45 copper at the attached-device layer while requiring 100GbE connectivity toward the network fabric. Extreme Networks 8522-48XT-6C-DC-F combines the 48-port copper configuration with six 100GbE uplinks, a DC power supply, and front-to-back fan airflow. DC power supports installations built around DC power distribution. Front-to-back cooling gives network architects a defined airflow orientation when placing the switch in equipment racks with managed intake and exhaust paths. Select this configuration when port media, uplink count, power type, and cooling direction must match the installed switching environment. Copper 10GbE interfaces provide RJ45-based connectivity for 10GBASE-T attached systems without requiring endpoint optical transceivers. Six 100GbE uplinks provide fabric-facing bandwidth beyond the copper access layer, allowing the switch to aggregate attached systems while retaining dedicated high-speed network connections. The distinguishing details of this configuration are its 48 copper 10GbE ports, six 100GbE uplinks, DC power option, and front-to-back fan arrangement.
