This product is no longer available for purchase.

Designed for virtualized data center and cloud environments, the AT-DC2552XS switch provides high density 10GbE and 40GbE connectivity, making it ideal for today’s big data, cloud and optimized workloads.

The AT-DC2552XS is a 48 x 10GbE (SFP+) port high-bandwidth and high-density switch designed for data center applications. It also provides four QSFP+ 40GbE slots for “fat-pipe” high bandwidth uplinks. This switch delivers 1280 Gbps of switching fabric with ultra low sub-μsec latency. Airflow has been optimized for front-to-back cooling for data center environments. The unit can also accommodate a 1+1 resilient power supply, all of this in a very compact 1RU unit chassis.
