Frequently Asked Questions

What is the primary interface configuration of the Arista DCS-7500RA-36Q-LC line card? +

The DCS-7500RA-36Q-LC is a high-density line card specifically designed for the Arista 7500R series chassis. It provides 36 ports of 40GbE QSFP+ connectivity, enabling massive throughput and port density for demanding data center fabrics. These ports support a variety of transceivers and cables, offering flexible connectivity options for high-bandwidth core or aggregation layer switching.

Which Arista switch chassis series supports the DCS-7500RA-36Q-LC module? +

This line card is engineered specifically for deployment within the Arista 7500R and 7500R2 series modular chassis. It is not compatible with the smaller 7000 series or fixed-configuration switches. Ensure your chassis backplane and supervisor modules support the R-series line cards to take full advantage of the deep packet buffering and increased scale capabilities.

What type of environment is the DCS-7500RA-36Q-LC best suited for? +

This module is ideal for large-scale data center environments, specifically those requiring high-performance leaf-spine architectures or deep-buffer IP storage networking. Its robust architecture handles bursty traffic flows with ease, making it a reliable choice for cloud providers and enterprise core networks that prioritize low latency and high availability at 40GbE speeds.

Does the DCS-7500RA-36Q-LC support specific Arista EOS features? +

Yes, this line card fully integrates with the Arista Extensible Operating System (EOS). It supports advanced features such as VXLAN routing, high-precision time stamping, and comprehensive telemetry options. By utilizing EOS, network administrators can maintain consistent operational control, automation, and programmable interfaces across their entire Arista-based infrastructure, ensuring seamless feature parity across the chassis.

How does the DCS-7500RA-36Q-LC handle heavy traffic bursts? +

The DCS-7500RA-36Q-LC is built with a deep-buffer architecture specifically optimized to handle heavy traffic bursts and congestion. This design minimizes packet loss during micro-bursts, which is critical for storage-heavy workloads and high-performance computing environments where consistent throughput is essential for maintaining application performance under varying network loads.

Are there specific power requirements for installing this line card in an Arista 7500R chassis? +

Installing this high-density module increases the power draw of the chassis. You must ensure that your 7500R switch chassis is populated with an adequate number of power supply units (PSUs) to support the total system load. It is recommended to perform a power budget calculation based on your full chassis configuration, including all supervisors, fabric modules, and active line cards.

What is the physical installation process for the DCS-7500RA-36Q-LC? +

The DCS-7500RA-36Q-LC is a hot-swappable module designed for front-loading into the 7500R chassis. Proper installation involves sliding the card into an available slot and securing the captive screws to ensure a firm connection with the backplane. Always follow standard ESD-safe practices and ensure the system is properly seated to maintain optimal thermal airflow and electrical connectivity.

Can the 40GbE ports on the DCS-7500RA-36Q-LC be broken out into 10GbE connections? +

Yes, the QSFP+ ports on this line card support breakout configurations, allowing you to split a single 40GbE port into four 10GbE SFP+ interfaces using compatible breakout cables. This versatility provides significant design flexibility, allowing you to transition between different speed requirements while maintaining density and optimizing the port utilization of your core switching infrastructure.
