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 with MACsec uplinks — professionally tested and ready to deploy.
This refurbished Arista DCS-7050SX3-48YC8C is a 1U, high-density data center switch delivering 48 ports of 1/10/25GbE via SFP/SFP28 and 8 QSFP+/QSFP28 uplinks supporting 40/100GbE. The C-model designation confirms MACsec-capable uplinks for encrypted fabric connectivity, while the front-to-back airflow configuration makes it purpose-built for hot-aisle data center deployments. Every unit has been professionally tested and reset to factory defaults in our ISO 9001-certified facility before shipment.Powered by Arista EOS, the 7050SX3-48YC8C supports VXLAN, EVPN, MLAG, advanced Layer 3 routing protocols, and a full automation stack including eAPI, gNMI, OpenConfig, and JSON-RPC. Ultra-low latency of approximately 800 ns makes it an ideal leaf node in spine-leaf fabrics serving high-performance compute, storage, and virtualized workloads. Dual hot-swappable power supplies and hot-swappable fans ensure continuous operation without planned downtime.
At $8,950, this unit delivers the full capability of Arista's 7050SX3 platform at a significant saving over new pricing — backed by WhaleyComm's Lifetime Warranty and 25 years of enterprise hardware expertise serving more than 5,000 customers worldwide.

Ideal Use Cases
High-Density 25GbE Server Access
With 48 SFP/SFP28 ports supporting 1/10/25GbE, this switch connects high-density server racks at full 25GbE line rate, making it a natural top-of-rack leaf node in modern data center fabrics.
100GbE Uplink Aggregation
Eight QSFP+/QSFP28 uplinks provide 40/100GbE connectivity to spine switches or core infrastructure, enabling scalable bandwidth aggregation without oversubscription constraints.
Secure Data Center Fabrics
MACsec-capable uplinks on the C-model encrypt inter-switch traffic at wire speed, satisfying compliance and security requirements in multi-tenant, financial, or government environments.
VXLAN/EVPN Leaf Deployments
Native EOS support for VXLAN, EVPN, and MLAG makes this switch a proven leaf node in overlay fabrics supporting workload mobility, multi-tenancy, and seamless VM migration.
Cloud, Virtualization, and Containerized Workloads
Deep telemetry via CloudVision, sFlow, and streaming APIs gives operations teams full visibility into traffic patterns, enabling rapid troubleshooting and capacity planning for dynamic workloads.
Low-Latency HPC, Storage, and Analytics
Approximately 800 ns typical latency and high-performance forwarding make this switch well-suited for latency-sensitive applications including high-performance compute clusters, all-flash storage networks, and real-time analytics pipelines.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
The C-model designation indicates that the 8x QSFP+/QSFP28 uplink ports are MACsec-capable, supporting IEEE 802.1AE encryption at wire speed. This allows the switch to encrypt traffic across inter-switch links without performance degradation, which is critical for secure multi-tenant or compliance-driven environments.
The -F suffix designates front-to-back airflow, meaning air enters at the port side and exhausts at the power supply side. This configuration is designed for hot-aisle containment data center layouts and should be matched accordingly when planning rack placement.
Arista EOS on the 7050SX3-48YC8C supports OSPF, IS-IS, BGP, EVPN, VXLAN, PIM SSM, and MLAG for control plane operations. Automation is supported via eAPI, gNMI, OpenConfig, JSON-RPC, and CloudVision integration for telemetry and orchestration.
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.
