The Refurbished Arista DCS-7280SR2A-48YC6-R is a purpose-built data center switch engineered to support high-performance, scale-out network architectures. Featuring 48 front-panel SFP28 ports capable of operating at 10G or 25G speeds, and 6 high-speed uplink ports supporting 40G or 100G connectivity, this switch delivers exceptional port density and forwarding throughput in a compact form factor.Built on Arista's proven EOS (Extensible Operating System), the DCS-7280SR2A-48YC6-R offers a consistent, programmable, and highly available network operating environment. EOS supports advanced features including VXLAN, BGP EVPN, and robust telemetry capabilities that simplify operations in modern cloud and enterprise data centers.
The '-R' suffix designates a rear-to-front airflow configuration, making it well-suited for data center deployments with hot-aisle/cold-aisle cooling architectures. Redundant power supplies contribute to high availability, reducing the risk of unplanned downtime in production environments.
Purchasing this unit as Refurbished through WhaleyComm provides a cost-effective path to enterprise-grade switching without sacrificing reliability. Each unit undergoes thorough inspection and testing prior to shipment. This makes the DCS-7280SR2A-48YC6-R an excellent choice for organizations looking to expand or upgrade their data center fabric while managing capital expenditure. Whether deploying in a leaf-spine topology or as a high-density ToR (Top-of-Rack) switch, this platform delivers the performance and feature depth required for modern workloads.

Ideal Use Cases
Data Center Leaf-Spine Fabric
The DCS-7280SR2A-48YC6-R is purpose-built for leaf-spine network designs, providing high-density 25G server connectivity with 100G uplinks to spine switches. Its low-latency forwarding and BGP EVPN support make it ideal for large-scale, east-west traffic environments.
High-Density Top-of-Rack Deployment
With 48 SFP28 ports supporting 10G or 25G server connections, this switch excels as a Top-of-Rack (ToR) aggregation point in modern data centers. It maximizes rack-level bandwidth while maintaining a compact 1RU footprint.
Network Refresh on a Controlled Budget
Organizations seeking to modernize aging network infrastructure without full capital expenditure can deploy this Refurbished unit to achieve enterprise-class 25G/100G performance. It delivers the same EOS feature set as new hardware at a fraction of the cost.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
The '-R' designation indicates rear-to-front airflow, meaning air flows from the rear of the chassis toward the front port side. This configuration is commonly used in hot-aisle/cold-aisle data center deployments where exhaust heat is directed into the hot aisle.
Yes, the Refurbished DCS-7280SR2A-48YC6-R runs Arista EOS, the same extensible and feature-rich operating system found on new units. Software licensing and support contract availability should be confirmed at time of purchase.
Yes, the SFP28 ports on this switch support both 10G and 25G speeds, providing backward compatibility with existing 10G optics and infrastructure while enabling 25G connectivity for newer servers and devices.
Each Refurbished unit is inspected and tested before shipment to ensure proper functionality. Included accessories such as power cords and rack mounting hardware should be confirmed with our sales team prior to purchase, as configurations may vary.
