Frequently Asked Questions

What are the primary port configurations for the Arista DCS-7500R-48S2CQ-LC line card? +

This line card is designed for the Arista 7500R series chassis and features 48 ports of 10/25GbE SFP+ connectivity, alongside 2 ports of 100GbE QSFP+ uplinks. This hybrid density allows for flexible high-performance integration into leaf-spine architectures, supporting varying bandwidth requirements within the data center fabric.

Which Arista switch chassis series is the DCS-7500R-48S2CQ-LC compatible with? +

The DCS-7500R-48S2CQ-LC is specifically engineered for deployment within the Arista 7500R and 7500R2 modular chassis series. Before installation, ensure your chassis is running a compatible version of Arista EOS and has sufficient power and cooling capacity to support the additional heat load and power draw of this specific line card module.

Does the DCS-7500R-48S2CQ-LC support deep buffering for data-intensive applications? +

Yes, this line card is part of the Arista R-series portfolio, which is renowned for its deep packet buffers. This architecture is specifically optimized for high-performance data centers, providing the necessary buffering to handle bursty traffic patterns and prevent packet loss in congestion-prone environments like big data analytics or distributed storage arrays.

What is the typical use case for deploying the DCS-7500R-48S2CQ-LC in a data center? +

This module is ideal for large-scale cloud data centers requiring a balance of high-density 25G server connectivity and high-speed 100G uplinks. It is frequently deployed in leaf-spine network designs where predictable latency, massive scalability, and robust traffic management are critical to maintaining application performance and network uptime.

How does the DCS-7500R-48S2CQ-LC handle advanced network virtualization? +

The line card leverages the capabilities of Arista EOS to provide comprehensive support for VXLAN routing and bridging. By facilitating hardware-based virtualized network overlays, it enables seamless multi-tenant cloud environments, allowing network administrators to decouple the physical network topology from the logical service requirements without sacrificing performance or hardware-level line-rate throughput.

Can I use the 100GbE ports on the DCS-7500R-48S2CQ-LC for spine-leaf interconnections? +

Absolutely. The 100GbE QSFP+ ports are designed to serve as high-capacity uplinks to the spine layer of your data center fabric. By connecting these to your spine switches, you create a high-bandwidth, low-latency backbone that supports the massive east-west traffic flows typical of modern scale-out architectures.

What management features are available when using the DCS-7500R-48S2CQ-LC? +

Management is handled through the centralized Arista EOS operating system running on the chassis supervisor modules. This ensures consistent configuration, monitoring, and troubleshooting across the entire line card. You gain access to advanced telemetry tools like CloudVision, which provides real-time visibility into port-level performance, traffic statistics, and potential congestion points across the infrastructure.

Is the DCS-7500R-48S2CQ-LC suitable for high-density 10GbE environments? +

The SFP+ ports on this line card are designed to be flexible, supporting both 10GbE and 25GbE transceivers. If your current server infrastructure operates primarily at 10GbE, you can utilize this card to maintain connectivity while establishing a clear upgrade path to 25GbE, effectively future-proofing your data center investment without requiring immediate wholesale hardware replacements.
