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.
The Cisco Nexus N3K-C3064TQ-10GT is a purpose-built data center switch engineered for high-throughput, low-latency deployments. As part of the Cisco Nexus 3000 Series, this 1RU fixed-configuration switch provides 48 x 10GbE RJ45 copper ports alongside 4 x 40GbE QSFP+ uplink ports, making it an ideal spine-leaf or top-of-rack (ToR) solution for modern data center architectures.
The RJ45 copper connectivity eliminates the need for costly SFP+ optics on every server connection, reducing infrastructure spend while maintaining full 10GbE line-rate performance to each endpoint. The four 40GbE QSFP+ uplinks provide high-bandwidth aggregation paths to spine or core switching layers, supporting scalable fabric designs.
Running Cisco NX-OS, the N3K-C3064TQ-10GT benefits from a mature, feature-rich operating system with support for advanced data center protocols including VXLAN, OSPF, BGP, ECMP, and robust QoS capabilities. Its ultra-low latency profile makes it well-suited for latency-sensitive workloads such as high-frequency trading, real-time analytics, and virtualized compute environments.
This Refurbished unit has been inspected and tested to ensure full operational functionality, offering enterprise-grade performance at a fraction of the new list price. WhaleyComm backs every Refurbished Cisco Nexus switch with professional support to keep your infrastructure running with confidence.

Ideal Use Cases
Top-of-Rack (ToR) Server Connectivity
Deploy the N3K-C3064TQ-10GT as a top-of-rack switch to deliver 10GbE copper connectivity directly to servers, eliminating optics costs at the server edge. The 40GbE QSFP+ uplinks provide high-bandwidth aggregation paths to spine switches in a leaf-spine fabric.
Data Center Leaf-Spine Fabric
The switch is well-suited as a leaf node in a modern leaf-spine architecture, supporting scalable east-west traffic patterns common in virtualized and containerized environments. Its low-latency forwarding and NX-OS protocol support enable seamless integration into software-defined networking designs.
High-Performance Computing and Analytics
Environments running latency-sensitive workloads such as real-time analytics, financial applications, or HPC clusters benefit from the Nexus 3000 Series' ultra-low latency architecture. The 48-port copper design simplifies cabling while maintaining wire-rate 10GbE performance to every connected node.
