Every WhaleyComm unit is professionally tested, reset to factory defaults, and certified by our in-house engineers — the same standard trusted by 5,000+ organisations across 25 years. Not a refurb marketplace. A certified lifecycle partner.
Tested to factory specification. Backed by 25 years of enterprise trust.
The Refurbished Arista DCS-7050SX-72Q-R is a 1RU fixed-configuration data center switch designed for organizations that demand high throughput, low latency, and operational simplicity. Equipped with 48x 10GbE SFP+ access ports and 6x 40GbE QSFP+ uplink ports, this switch provides exceptional port density in a compact form factor ideal for top-of-rack (ToR) or aggregation deployments.
Powered by Arista's industry-renowned Extensible Operating System (EOS), the DCS-7050SX-72Q-R delivers consistent, programmable network management with full support for open standards and automation frameworks including NETCONF, OpenConfig, and eAPI. The "-R" suffix denotes rear-to-front airflow, making it well-suited for hot-aisle/cold-aisle data center cooling configurations.
Sourced, inspected, and tested by WhaleyComm, this Refurbished unit provides a cost-effective path to enterprise-class switching without sacrificing performance or manageability. Whether you are scaling an existing Arista fabric, building out a new leaf layer, or refreshing aging infrastructure, the DCS-7050SX-72Q-R delivers proven 7050SX-series performance at a compelling price point of $500.00.
All WhaleyComm Refurbished units undergo functional testing prior to shipment, helping your organization maximize IT budget efficiency while maintaining network integrity.

Ideal Use Cases
Top-of-Rack (ToR) Server Access
Deploy the DCS-7050SX-72Q-R as a top-of-rack switch to connect high-density 10GbE server populations directly at the rack level. The 48 SFP+ downlinks support full server connectivity while the 6x 40GbE QSFP+ ports provide high-bandwidth uplinks to spine or aggregation layers.
Spine-Leaf Fabric Expansion
Integrate the DCS-7050SX-72Q-R as a leaf node within an existing or new spine-leaf architecture to scale east-west traffic capacity cost-effectively. Its EOS compatibility ensures seamless integration with existing Arista infrastructure and automation toolchains.
High-Performance Computing (HPC) and Virtualization Clusters
Support demanding workloads such as virtualized environments, storage area networks, and HPC clusters that require consistent low-latency, high-throughput switching. The non-blocking architecture ensures predictable performance under heavy, simultaneous traffic loads.
