Arista DCS-7130-48LBAS-R | 7130L 48-Port 10G SFP+ Switch, VU9P-3 FPGA, Atomic Clock

Q: What is the purpose of the integrated atomic clock in the DCS-7130-48LBAS-R?
A: The atomic clock provides high-precision timing and synchronization for applications requiring sub-microsecond accuracy, such as high-frequency trading, financial market data distribution, and telecom applications. It supports IEEE 1588v2 PTP and PPS inputs for enhanced timing accuracy.

Q: Does this switch require additional components to operate?
A: Yes, the DCS-7130-48LBAS-R requires a separate PSU/Fan kit which is sold separately. Arista offers compatible power supply options including the PWR-500-AC and PWR-500-DC units for redundant operation.

Q: What makes the 7130L Series different from standard switches?
A: The 7130L Series combines Layer 1+ switching with an integrated FPGA platform and x8664 server in a single device. It performs ultra-low latency bit-level forwarding without buffering or queuing, making it ideal for financial trading, network tapping, media conversion, and custom FPGA application deployment.

Q: Can I develop custom applications for this switch?
A: Yes, Arista provides a comprehensive FPGA Development Kit with APIs, documentation, and IP cores that allow developers to create custom network applications. The switch provides unrestricted access to the Xilinx VU9P-3 FPGA with 32GB of onboard DDR4 memory.

Q: What is the difference between models with and without the A suffix?
A: Models with the 'A' suffix include an integrated atomic clock for precision timing applications. The DCS-7130-48LBAS-R includes the atomic clock, while the DCS-7130-48LBS-R does not. The atomic clock provides enhanced timing accuracy for synchronization-sensitive applications.
