AT-x900-24XT The x900-24XT is one of the most advanced Gigabit Ethernet switches available, with two high-speed 30Gbps expansion bays providing a high level of port flexibility and application versatility unmatched by any other 1RU Gigabit Ethernet switch on the market. Expansion modules offer 10GbE, gigabit fiber, gigabit copper, and stacking expansion options. These can be used in a variety of configurations to provide tailored solutions that meet wide-ranging physical networking requirements. The most flexible non-chassis switch available today, the x900-24XT provides fine service provisioning granularity, high availability, advanced QoS, and shares the same modular power supplies used by other x900 series switches.
