Tested
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-7050S-64-F is a 1RU 10/40G data center switch delivering wire-speed Layer 2/3/4 performance. It features 48 x 1/10GbE SFP+ ports and 4 x 40GbE QSFP+ uplink ports with front-to-rear airflow and dual 460W redundant AC power supplies — purpose-built for high-density data center and enterprise core deployments. Every unit is reset to factory defaults and ships with a Certificate of Testing.The DCS-7050S-64-F is built on the Broadcom Trident+ ASIC and delivers a switching capacity of 1.28 Tbps and a forwarding rate of 960 Mpps at wire speed. Cut-through forwarding keeps latency between 800 ns and 1.2 µs, while a 9 MB Dynamic Buffer Allocation pool manages congestion without per-port memory constraints. Each QSFP+ port can operate as a single 40GbE uplink or break out into four independent 10GbE ports, effectively expanding the switch to 64 total 10GbE ports. The unit runs Arista EOS — a modular, Linux-based operating system supporting Zero Touch Provisioning (ZTP), VMTracer, OpenFlow, and full REST API automation. A dual-core x86 CPU and 4 GB DRAM support a resilient, in-service-upgradeable control plane.
Sourcing refurbished Arista infrastructure from WhaleyComm delivers enterprise-grade 10/40G performance at a fraction of new list price. WhaleyComm is ISO 9001, R2v3, e-Stewards, and UNEDA certified, and has served 5,000+ enterprise customers for 25+ years. The DCS-7050S-64-F is an ideal choice for organizations standardizing on leaf-spine architectures or refreshing access/aggregation layers without budget compromise.

Ideal Use Cases
Data Center Leaf Switch
With 48 × 10GbE SFP+ and 4 × 40GbE QSFP+ uplinks, the DCS-7050S-64-F is purpose-designed as a leaf node in Arista leaf-spine architectures, supporting up to 18,000 10GbE nodes at scale.
High-Density Server Access Layer
The switch's 48-port 10GbE density and sub-microsecond cut-through latency make it ideal for directly connecting high-performance compute, storage, and virtualization hosts.
Campus or Enterprise Core Aggregation
Wire-speed Layer 2/3/4 forwarding at 960 Mpps with full routing support in a compact 1RU chassis makes this switch a cost-efficient core or aggregation layer upgrade for enterprise networks.
Financial Services / Low-Latency Environments
Cut-through forwarding delivering 800 ns to 1.2 µs latency suits latency-sensitive applications such as algorithmic trading platforms, real-time analytics, and financial transaction systems.
HPC and Storage Networking
The combination of 1.28 Tbps switching capacity, Dynamic Buffer Allocation, and QSFP+ breakout flexibility enables lossless, high-throughput interconnects for HPC clusters and all-flash storage networks.
Network Refresh / Budget-Conscious Upgrades
Organizations looking to deploy or expand 10/40G infrastructure without new-hardware pricing can leverage this professionally tested refurbished unit at significant savings while maintaining enterprise reliability.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
The DCS-7050S-64-F delivers a switching capacity of 1.28 Tbps and a forwarding rate of 960 Mpps. Wire-speed Layer 2, Layer 3, and Layer 4 forwarding is supported across all 48 SFP+ and 4 QSFP+ ports simultaneously.
Yes. Each of the four QSFP+ ports can operate as a single 40GbE uplink or be broken out into four independent 10GbE ports, bringing the total potential 10GbE port count to 64. This provides significant flexibility for spine connectivity or high-density server access.
The switch runs Arista EOS, a modular Linux-based operating system. EOS supports Zero Touch Provisioning (ZTP), VMTracer, REST API, OpenFlow, and other automation tools natively on the switch's dual-core x86 CPU with 4 GB DRAM.
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.
