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.
Enterprise-grade 100G switching at a fraction of new-unit cost. Professionally tested. Backed by a Lifetime Warranty.
This listing is for a professionally tested, refurbished Arista DCS-7050CX3-32S-F switch, reset to factory defaults and ready for immediate enterprise deployment. Part of the Arista 7050X3 Series, this 1RU fixed-configuration platform delivers 32 x 100GbE QSFP100 ports and 2 x SFP+ management or uplink ports, with front-to-rear airflow and dual hot-swappable AC power supplies included. Each unit has been subjected to full power-on diagnostics, port-by-port functionality testing, and firmware verification before shipping.The DCS-7050CX3-32S-F is built around a non-blocking architecture delivering up to 6.4 Tbps of switching capacity and up to 2 billion packets per second forwarding performance. Each QSFP100 port supports flexible multi-speed operation — 100GbE, 40GbE, 4x25GbE, 4x10GbE, or 2x50GbE — enabling up to 128 downstream 10G or 25G breakout connections from a single 1RU chassis. A fully shared 32MB packet buffer provides superior burst absorption, and latency starts as low as 800 nanoseconds. The switch runs Arista EOS, offering extensive automation, programmability, streaming telemetry, and support for VXLAN and EVPN for modern cloud and virtualized fabrics.
Purchasing refurbished through WhaleyComm delivers the same Arista 7050X3 performance at a significant cost reduction compared to new-unit pricing. WhaleyComm has served 5,000+ enterprise customers over 25+ years with ISO 9001, R2v3, e-Stewards, and UNEDA certifications — every unit ships with a Lifetime Warranty and a Certificate of Testing.

Ideal Use Cases
Data Center Leaf Switch
The DCS-7050CX3-32S-F delivers 32 ports of wire-speed 100GbE in 1RU, making it purpose-built for high-density leaf roles in modern leaf-spine fabrics where low latency and no oversubscription are critical.
Collapsed Spine Deployment
With 6.4 Tbps of non-blocking capacity and flexible QSFP breakout options, this switch serves equally well as a collapsed spine node in mid-scale data centers that require both server access and inter-rack aggregation from a single platform.
40G-to-100G Migration
Each QSFP100 port supports 100GbE, 40GbE, and multi-speed breakout modes, allowing teams to migrate from 40G infrastructure incrementally without replacing downstream cabling or optics.
Cloud and Virtualized Environments
Native VXLAN and EVPN support combined with Arista EOS automation capabilities make this switch a natural fit for private cloud, multi-tenant, and software-defined networking environments.
High-Performance Compute and Storage Fabrics
The 800ns latency floor and 32MB shared packet buffer allow the switch to absorb traffic microbursts efficiently, supporting latency-sensitive compute clusters, distributed storage, and east-west workloads.
Enterprises Upgrading Core Switching
Organizations refreshing 10G or 40G core infrastructure can leverage refurbished DCS-7050CX3-32S-F units from WhaleyComm to reach 100G performance at a fraction of new-unit cost, without compromising on feature richness or reliability.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
Yes. Each of the 32 QSFP100 ports supports breakout modes including 4x25GbE and 4x10GbE, enabling up to 128 downstream 10G or 25G connections from a single switch. This makes the platform highly flexible for environments with mixed-speed endpoints.
The -F suffix designates front-to-rear airflow, meaning air enters from the front (cold aisle) and exhausts from the rear (hot aisle). This airflow direction is the standard for hot-aisle/cold-aisle data center rack configurations and should be confirmed against your rack layout before installation.
The DCS-7050CX3-32S-F runs Arista EOS (Extensible Operating System), which supports Layer 2, Layer 3, VXLAN, EVPN, automation APIs, and streaming telemetry. Arista EOS uses the same license structure as other 7000 Series fixed platforms — contact our engineering team at +1 214 607-4800 or sales@whaleycomm.com to discuss licensing requirements for your 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.
Every unit goes through our ISO 9001-certified testing process: full power-on diagnostics, port-by-port functionality testing, firmware verification, factory reset, and final inspection. A Certificate of Testing ships with every unit.
