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-7050TX-64-F is a fixed-configuration 1RU data center switch from the Arista 7050TX Series, delivering 48x 1/10GBASE-T RJ45 ports and 4x 40GbE QSFP+ uplink ports in a compact, energy-efficient chassis. The -F suffix designates front-to-back airflow, designed to align with hot-aisle/cold-aisle data center cooling architectures. Dual AC power supplies (PWR-500AC-F) are included for built-in redundancy. Every unit ships reset to factory defaults and accompanied by a Certificate of Testing.
The DCS-7050TX-64-F delivers a switching capacity of 1.28 Tbps and a forwarding rate of 960 Mpps at sub-3-microsecond cut-through latency — making it purpose-built for latency-sensitive east-west data center traffic. The switch features a shared 12 MB dynamic packet buffer with Dynamic Buffer Allocation (DBA), a Unified Forwarding Table supporting up to 288,000 MAC entries, and runs Arista EOS, the industry's leading modular network operating system. EOS delivers wire-speed Layer 2 and Layer 3 forwarding, VXLAN bridging and routing, EVPN, Zero Touch Provisioning (ZTP), the Arista Latency Analyzer (LANZ) for microburst detection, sFlow, and full network automation APIs — all from a single consistent software image.
Purchasing this refurbished Arista DCS-7050TX-64-F from WhaleyComm delivers enterprise-grade 10/40GbE leaf switching at a fraction of new list price. WhaleyComm has served 5,000+ enterprise customers over 25+ years under ISO 9001, R2v3, e-Stewards, and UNEDA certifications — so every unit you receive is held to the same standard as day-one hardware.

Ideal Use Cases
Data Center Leaf Switch (Leaf-Spine Architecture)
With 48x 10GBASE-T server-facing ports and 4x 40GbE uplinks, the DCS-7050TX-64-F is an ideal leaf node in a two-tier leaf-spine fabric, supporting 64-way ECMP and MLAG for balanced, high-bandwidth east-west traffic.
Virtualized and Cloud-Driven Environments
Native VXLAN routing and bridging, EVPN support, and Arista VM Tracer integration make this switch purpose-built for VMware and OpenStack environments requiring seamless physical-to-virtual network connectivity.
Low-Latency High-Performance Computing (HPC)
Sub-3-microsecond cut-through latency and 1.28 Tbps non-blocking switching capacity make the DCS-7050TX-64-F well-suited for financial, AI/ML inference, or HPC workloads where latency consistency is critical.
10GbE Server Access Migration
Auto-negotiating 100Mb/1G/10GBASE-T ports allow organizations to migrate existing copper-cabled server farms to 10GbE without replacing cabling infrastructure, protecting prior investments.
Network Automation and DevOps Integration
Arista EOS exposes a full programmatic API (eAPI), supports ZTP, and integrates with Ansible, Puppet, and Chef — making this switch a natural fit for infrastructure-as-code and automated provisioning workflows.
Enterprise Core or Aggregation Layer
Rich Layer 3 features, EVPN, sFlow telemetry, and LANZ microburst detection make this switch a capable aggregation layer node for enterprise campus and private cloud environments requiring visibility and control.
