Connect 48 copper-based 10 Gigabit devices while retaining six 100Gb uplinks for aggregation, spine connectivity, or high-capacity server and storage traffic. The 48 10GBASE-T interfaces provide a high-density copper switching layer for equipment that requires RJ45 connectivity, while the 100Gb QSFP28 uplink interfaces concentrate traffic toward the network core. DC power and back-to-front airflow make this configuration suitable where the rack power plant and cooling path are already defined. Back-to-front fans draw air through the switch from the port side toward the power side, allowing the unit to align with racks built around that airflow direction. The DC-powered architecture supports environments that standardize on DC distribution rather than AC branch power. Extreme Networks 8522-48XT-6C-DC-R combines the 48XT copper access configuration with six C-class 100Gb uplinks, DC power, and B-F fan direction. Within the 8522 family, those configuration elements matter when matching port media, uplink density, power input, and airflow to an existing network design. It serves as a dense 10Gb copper aggregation platform where high-bandwidth uplinks prevent the access layer from becoming a bottleneck.
