Frequently Asked Questions

What is the primary function of the Arista DCS-7500R-36Q-LC line card? +

The DCS-7500R-36Q-LC is a high-density, versatile line card designed for the Arista 7500R Series modular chassis. It provides massive throughput and deep packet buffering, specifically engineered to handle demanding data center workloads, large-scale cloud networks, and high-performance routing environments where traffic spikes and congestion management are critical for maintaining low-latency operations.

How many ports and what type of interfaces does the DCS-7500R-36Q-LC support? +

This specific line card is equipped with 36 QSFP+ ports. These interfaces are designed to support 40GbE connectivity, providing high-bandwidth capacity per slot. By leveraging the Arista 7500R series modular architecture, this card enables flexible density scaling, allowing network administrators to achieve massive port counts within a single chassis for core and aggregation layer deployments.

Is the DCS-7500R-36Q-LC compatible with existing Arista 7500R Series chassis? +

Yes, this line card is fully compatible with the Arista 7500R Series modular switches. It is built to integrate seamlessly into these chassis systems, ensuring that organizations can scale their network infrastructure without needing to replace the existing backbone. Ensure your chassis supervisor modules and power supplies are properly configured to support the power requirements of adding additional high-density line cards.

What makes this line card suitable for high-performance routing and data center use? +

The DCS-7500R-36Q-LC features Arista’s R-Series architecture, which is renowned for its deep buffers. These buffers are essential for absorbing bursty traffic common in modern data center environments, preventing packet loss during congestion. Combined with high-density 40GbE connectivity, it provides the deterministic performance and robust routing table capacity required for internet peering and complex leaf-spine fabric designs.

What is the management approach for the Arista DCS-7500R-36Q-LC? +

Management is handled through the Arista Extensible Operating System (EOS). This robust, programmable platform allows for automated provisioning, comprehensive monitoring, and deep visibility into network traffic. Because the card operates within the 7500R modular system, it is managed as a single integrated entity via the primary supervisor modules, simplifying orchestration across the entire switch fabric through familiar CLI, API, or automated management tools.

Does the DCS-7500R-36Q-LC support advanced networking protocols? +

Being part of the Arista 7500R series, this line card supports a comprehensive suite of Layer 2 and Layer 3 protocols. This includes robust support for BGP, OSPF, IS-IS, and advanced features like VXLAN and EVPN. These capabilities make it an ideal choice for constructing sophisticated, software-defined network (SDN) overlays and scalable multi-tenant cloud data center architectures.

How should I plan for power and cooling when installing this line card? +

When deploying the DCS-7500R-36Q-LC, it is vital to consult the chassis power budget and thermal requirements. High-density cards require adequate airflow and power allocation from the chassis power supplies. Always verify that your current chassis configuration has the necessary capacity to support the additional draw of a populated 36-port QSFP+ module to ensure optimal performance and system stability under load.

What deployment scenarios are best for the 36Q-LC line card? +

This line card excels in core data center routing, high-density leaf-spine fabrics, and large-scale IP peering points. Its design focuses on balancing port density with deep buffering, making it exceptionally reliable for service providers and enterprise networks that require consistent, high-bandwidth throughput for video streaming, cloud applications, and distributed storage systems where low latency and high availability are strictly enforced.

How can I obtain a bulk quote for multiple Arista DCS-7500R-36Q-LC units? +
