Connect high-density copper infrastructure to high-speed aggregation links with the Extreme Networks 8522-48XT-6C-AC-F managed Ethernet switch. Its fixed interface layout combines 48 10GBASE-T RJ45 ports for copper-connected equipment with six 100GbE QSFP28 ports for optical uplinks. This port mix addresses environments where many locally attached systems require 10GbE access while upstream paths need substantially higher bandwidth. Deploy the switch at the top of a rack, in a server-access layer, or as a copper aggregation point feeding a higher-capacity network tier. The 48 RJ45 ports provide concentrated access capacity for systems equipped with 10GbE copper interfaces, while the six QSFP28 ports create multiple options for connecting aggregation, spine, or core infrastructure. Keeping copper endpoint connectivity and 100GbE uplinks in one fixed switch reduces the need to dedicate separate platforms to those two interface roles. The 48XT-6C configuration is defined by its 48-port 10GbE copper access count and six-port 100GbE QSFP28 uplink capacity. It includes an AC power supply and front-to-back fan airflow, making airflow direction an important consideration when placing it in a rack with established intake and exhaust patterns. Buyers selecting this configuration should match both the required copper port count and the available QSFP28 uplink design to the intended rack or aggregation layer.
