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.
This professionally tested, refurbished Arista DCS-7050QX-32-R is a purpose-built 1RU data center switch delivering 32 × QSFP+ ports at 40 Gigabit Ethernet with rear-to-front (exhaust-front) airflow and dual 460W hot-swappable AC power supplies. Every unit has been reset to factory defaults, verified against Arista EOS firmware requirements, and issued a Certificate of Testing before shipment.Part of the Arista 7050X Series, the DCS-7050QX-32-R delivers a non-blocking switching capacity of 2.56 Tbps and a forwarding rate of 1,440 Mpps with cut-through latency as low as 550 ns. The switch supports flexible port breakout — up to 96 × 10GbE and 8 × 40GbE — alongside a 12 MB dynamic packet buffer pool for burst absorption. Advanced data center features include VXLAN bridging and routing, 64-way ECMP, 64-way MLAG, sFlow, DANZ multi-port mirroring, and the Arista Latency Analyzer (LANZ) for real-time micro-burst visibility. The switch runs Arista EOS, the same extensible operating system across all Arista platforms, enabling consistent automation, eAPI programmability, and CloudVision integration.
Purchasing a refurbished Arista DCS-7050QX-32-R through WhaleyComm delivers enterprise-grade 40G spine or leaf capability at a fraction of new list price — without compromising on reliability, warranty, or support. Backed by WhaleyComm's Lifetime Warranty and ISO 9001-certified testing process, this is the intelligent choice for cost-conscious data center teams that refuse to settle on performance.

Ideal Use Cases
Data Center Leaf-Spine Fabric
The DCS-7050QX-32-R's 2.56 Tbps non-blocking capacity and 64-way ECMP make it a natural fit as either a spine or leaf node in two-tier data center architectures handling east-west traffic at scale.
High-Performance Compute (HPC) Clusters
With 550 ns cut-through latency and dense 40GbE port density, this switch delivers the predictable, low-jitter connectivity demanded by HPC workloads, financial trading platforms, and real-time analytics environments.
Cloud and Virtualized Data Centers
Native VXLAN bridging, routing, and gateway support — combined with VM Tracer and eAPI programmability — make this switch ideal for software-defined cloud networking and virtualized infrastructure deployments.
Enterprise Core / Aggregation Layer
Wire-speed Layer 2 and Layer 3 forwarding, robust OSPF/BGP routing, and MLAG support allow the DCS-7050QX-32-R to serve as a high-throughput aggregation or core switch in large enterprise campuses.
Network Capacity Expansion on a Budget
Organizations upgrading aging 10G infrastructure to 40G can do so at a significant cost savings over new equipment — without sacrificing performance, redundancy, or Arista EOS feature parity.
Big Data and Storage Networking
The flexible breakout to 96 × 10GbE combined with a 12 MB dynamic buffer pool and DANZ monitoring makes this switch well-suited for storage fabric and big data environments requiring burst tolerance and deep visibility.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
The DCS-7050QX-32-R uses rear-to-front airflow, meaning cool air enters from the rear of the chassis and exhausts out the front. This is the standard configuration for hot-aisle/cold-aisle data center designs where the rear of the rack faces the cold aisle. Confirm your rack's airflow pattern before deploying to ensure compatibility.
The switch supports flexible port breakout — up to 24 QSFP+ ports can each be broken out into 4 × 10GbE, enabling configurations of up to 96 × 10GbE and 8 × 40GbE simultaneously. This makes the switch highly versatile for mixed 10G and 40G environments without requiring additional hardware.
The DCS-7050QX-32-R runs Arista EOS, the same unified operating system used across all Arista platforms. Base L2/L3 features are included; advanced features such as enhanced L3 routing (BGP, OSPF, ISIS, PIM, NAT) may require an optional Arista LIC-FIX-2-E license. Contact our team at +1 214 607-4800 to confirm the license posture for your use case before deployment.
Yes. Every WhaleyComm unit ships with a Lifetime Warranty. If it fails under normal operating conditions at any point, we replace it at no cost — no time limits, no questions asked.
