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 25GbE leaf switching, professionally tested and backed by a Lifetime Warranty.
This refurbished Arista DCS-7050SX3-48YC8-F has been professionally tested and reset to factory defaults, delivering the same wire-speed performance as new at a fraction of the cost. The switch provides 48 ports of 1/10/25GbE connectivity via SFP/SFP28 and 8 uplink ports of 40/100GbE via QSFP+/QSFP28, all in a compact 1U form factor with front-to-back airflow suited for hot-aisle data center deployments.Powered by Arista EOS, the 7050SX3-48YC8-F delivers approximately 4 Tbps of switching capacity and approximately 3 Bpps forwarding rate with sub-microsecond latency. It supports VXLAN, EVPN, MLAG, BGP, OSPF, IS-IS, PIM SSM, and 128-way ECMP, making it equally capable as a high-density leaf node in a spine-leaf fabric or as a top-of-rack access switch for 25GbE server deployments. Deep packet buffers protect against traffic bursts, and programmable interfaces including eAPI, JSON-RPC, gNMI, and OpenConfig enable full automation integration.
WhaleyComm has served 5,000+ enterprise customers across 25+ years, and every unit ships with our Lifetime Warranty. Choosing refurbished Arista hardware through WhaleyComm means certified quality, significant savings versus new list price, and the assurance of our ISO 9001, R2v3, and e-Stewards certifications.

Ideal Use Cases
Leaf Node in Spine-Leaf Fabric
The 48 x 25GbE downlinks and 8 x 100GbE uplinks make this switch a natural leaf node in Clos-based spine-leaf architectures, supporting VXLAN/EVPN overlays and 128-way ECMP for optimal traffic distribution.
High-Density 25GbE Server Access
Connects up to 48 servers at 25GbE line rate in a single 1U unit, ideal for dense compute environments including virtualization clusters and hyperconverged infrastructure.
Low-Latency HPC and Storage Networking
Sub-microsecond latency and deep packet buffers make this switch well-suited for high-performance computing, all-flash storage fabrics, and latency-sensitive analytics workloads.
Multi-Tenant Cloud Environments
Native VXLAN, EVPN, and VRF support enable scalable network segmentation for multi-tenant private cloud and hosted enterprise environments.
Network Automation and Telemetry
eAPI, JSON-RPC, gNMI, OpenConfig, and sFlow support allow deep integration with automation platforms and monitoring pipelines, including Arista CloudVision.
100GbE Uplink Aggregation
Eight 100GbE QSFP28 uplinks provide substantial northbound bandwidth for aggregating high-density server traffic toward spine or core layers.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
The -F suffix designates front-to-back airflow, meaning air enters at the port side and exhausts at the PSU/fan side. This configuration is designed for hot-aisle containment deployments standard in modern data centers.
Yes. The DCS-7050SX3-48YC8-F runs Arista EOS and supports VXLAN encapsulation, BGP EVPN control plane, and MLAG out of the box. These features are standard EOS capabilities and do not require additional hardware.
The switch supports BGP, OSPF, IS-IS, PIM SSM, ECMP (up to 128-way), and VRF-based segmentation under Arista EOS, covering the full range of requirements for enterprise and cloud data center routing.
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.
