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-7050QX-32S-R is a purpose-built data center switch from Arista's proven 7050X series platform, engineered to deliver high-density 40 Gigabit Ethernet connectivity in a compact 1U form factor. With 32 x QSFP+ ports supporting 40GbE and 4 x SFP+ ports for flexible uplink options, this switch is well-suited for spine-leaf architectures, high-performance computing environments, and bandwidth-intensive enterprise workloads.Powered by Arista's EOS (Extensible Operating System), the DCS-7050QX-32S-R provides a consistent, programmable network operating environment with robust support for automation, streaming telemetry, and open APIs. EOS enables seamless integration with orchestration platforms and DevOps workflows, making this switch a strong fit for software-defined and cloud-style networking deployments.
The rear-to-front (-R) airflow designation ensures compatibility with hot-aisle/cold-aisle data center cooling architectures. Redundant power supply support further enhances availability for mission-critical environments.
Purchasing this unit in Refurbished condition from WhaleyComm provides an excellent opportunity to deploy enterprise-grade Arista switching infrastructure while optimizing capital expenditure. All Refurbished units are inspected and tested to ensure reliable performance.

Ideal Use Cases
Data Center Spine-Leaf Architecture
The DCS-7050QX-32S-R's 32 high-density 40GbE QSFP+ ports make it an excellent spine or leaf switch in modern Clos-based data center fabrics. Its low-latency performance and EOS programmability support scalable, automated east-west traffic architectures.
High-Performance Computing (HPC) Clusters
Organizations running compute-intensive workloads such as analytics, AI/ML training, or simulation can leverage the switch's 40GbE density to interconnect servers with minimal bottlenecks. The line-rate switching capability ensures consistent throughput across all connected nodes.
Enterprise Network Upgrades and Refresh Projects
IT teams looking to refresh aging core or aggregation switching infrastructure at a controlled cost will find the Refurbished DCS-7050QX-32S-R a compelling option. It delivers carrier-grade Arista performance and EOS feature parity at a fraction of new unit pricing.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
The "-R" suffix indicates rear-to-front airflow direction, meaning cooling air enters from the rear (non-port side) of the switch and exhausts out the front (port side). This is designed for hot-aisle/cold-aisle data center environments where server and switch ports face the cold aisle.
Yes, the DCS-7050QX-32S-R runs Arista EOS, which is fully compatible with Arista CloudVision (CVP) for centralized management, zero-touch provisioning, and network-wide telemetry collection.
The 32 QSFP+ ports support standard 40GbE optics including 40GBASE-SR4 and 40GBASE-LR4 transceivers, as well as QSFP+ Direct Attach Copper (DAC) cables. Always verify transceiver compatibility with the Arista hardware compatibility list before deployment.
Refurbished means the unit has been previously deployed and has since been inspected and tested to verify functionality and performance. WhaleyComm sources quality Refurbished enterprise hardware to provide cost-effective solutions without sacrificing reliability for your network infrastructure.
