AT-x900-24XT, 2 x 30Gbps expansion bays, 24 x 10/100/1000BASE-T (RJ-45) copper ports
Unmatched Flexibility
The x900-24X Layer 3+ switches have two highspeed 30Gbps expansion bays which provide a high level of port flexibility and application versatility unmatched by any other 1RU Gigabit Ethernet switch on the market.The expansion modules can be used in a variety of configurations to provide tailored solutions that meet wideranging physical networking requirements.
10GbE expansion modules and hot-swappable XFPs provide high-speed, high-capacity fiber uplinks, with the option of either 10Gbps or 20Gbps uplink capacity to the network core. Resiliency can be achieved by using two 10GbE modules and MSTP (802.1s) for fast failover on link failure.This is suitable for wiring closet aggregation of gigabit to the desktop links and aggregating gigabit uplinks from other network switches.
Ethernet Protected Switched Rings (EPSR) and 10 GbE modules allow several x900-24X switches to form a protected ring with sub 50ms failover.This feature is perfect for high performance at the core of enterprise or provider access networks.
Combined with one or two 12-port 10/100/1000BASE-T (RJ-45) copper expansion modules, the x900-24X is ideal for gigabit to the desktop or gigabit aggregation applications. The 12 x 1000BASE-X (SFP) expansion modules offer variable port options, designed for aggregating mixed copper and fiber links in server farms and data center applications.
