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-7050CX3-32S-R delivers enterprise-grade, high-density 100 Gigabit Ethernet switching in a compact 1RU form factor. Equipped with 32x QSFP100 ports and 2x SFP+ ports, this switch is purpose-built for demanding spine, leaf, and top-of-rack deployments in modern data centers.



The rear-to-front (port-side exhaust) airflow design integrates seamlessly into standard hot-aisle/cold-aisle cooling architectures, supporting efficient thermal management in high-density server environments. This makes the DCS-7050CX3-32S-R an ideal choice for organizations looking to optimize airflow without costly infrastructure changes.



Running Arista EOS (Extensible Operating System), this switch provides a single, consistent software image across the Arista portfolio, enabling advanced features including streaming telemetry, zero-touch provisioning (ZTP), and deep integration with network automation frameworks such as Ansible, Puppet, and Python APIs. EOS also supports BGP EVPN for scalable VXLAN overlay networking.



Sourced as a Refurbished unit, the DCS-7050CX3-32S-R offers significant cost savings over new pricing while still delivering the performance and reliability Arista is known for. Each unit is tested and verified prior to shipment, making it an excellent choice for budget-conscious enterprises, lab environments, and network expansions.



WhaleyComm provides competitive pricing and reliable fulfillment on Refurbished Arista hardware to help your organization scale without compromise.
