Arista DCS-7132LB-48Y4C-R | 7132LB 48-Port 25G Switch, 4x 100G QSFP28, VU9P FPGA

Q: What is the primary use case for the DCS-7132LB-48Y4C-R?
A: This switch is designed for ultra-low latency applications including high-frequency trading, financial markets, telecom infrastructure, and media & entertainment networks requiring sub-microsecond forwarding and precise timing synchronization.

Q: What does the FPGA enable on this switch?
A: The integrated Xilinx VU9P-3 FPGA allows customers and partners to develop and deploy custom network applications, packet processing, filtering, timestamping, and traffic management functions using Arista's FPGA Development Kit.

Q: What port speeds and configurations are supported?
A: The 48 SFP28 ports support 10GbE or 25GbE, and the 4 QSFP28 ports support 40GbE or 100GbE. QSFP28 ports can also be broken out to 4x 10GbE or 4x 25GbE, providing flexible deployment options.

Q: Does this switch require additional licenses for Layer 3 routing?
A: Yes, advanced Layer 3 features such as BGP, OSPF, ISIS, PIM, and NAT require the LIC-FIX-2-E Enhanced L3 License. Additional licenses are available for virtualization, automation, and MPLS functionality.

Q: What is the difference between the -R and -F model variants?
A: The -R suffix indicates rear-to-front airflow (exhaust toward front), while the -F variant has front-to-rear airflow (exhaust toward rear). Select the appropriate model based on your data center hot/cold aisle design.
