Arista DCS-7130-48LAS-R | 7130 48-Port 10G FPGA Switch, Atomic Clock, VU7P-2

Q: What makes the DCS-7130-48LAS-R different from the 48LS model?
A: The 48LAS variant includes an integrated atomic clock for sub-nanosecond timing precision, making it ideal for high-frequency trading and applications requiring exact time synchronization. The 48LS model does not include the atomic clock.

Q: Does this switch include power supplies and fans?
A: No, the DCS-7130-48LAS-R requires separate power supply and fan modules. Compatible power supplies include PWR-460-AC and PWR-500-AC units, which must be ordered separately.

Q: What is the FPGA used for in this switch?
A: The Xilinx UltraScale VU7P-2 FPGA enables programmable network applications including ultra-low latency multiplexing, precision timestamping, tap aggregation, and custom application development for trading and financial services environments.

Q: What is the difference between -R and -F airflow models?
A: The -R suffix indicates rear-to-front airflow (port-side intake, fan-side exhaust), while -F models feature front-to-rear airflow. Choose based on your data centre hot aisle/cold aisle configuration requirements.

Q: What are typical use cases for this switch?
A: The DCS-7130-48LAS-R is designed for ultra-low latency applications including high-frequency trading, exchange connectivity, market data distribution, algorithmic trading infrastructure, and financial services networks requiring sub-nanosecond timing precision.
