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.
Wire-rate 100G cloud-scale switching, professionally tested and backed by a Lifetime Warranty.
This refurbished Cisco Nexus N9K-C9336C-FX2 is a 36-port 40/100G fixed switch from the Nexus 9300-FX2 Series, professionally tested and reset to factory defaults before shipment. Every unit is verified through WhaleyComm's ISO 9001-certified process, ensuring the same reliability you would expect from new hardware at a fraction of the cost.Built on Cisco's Cloud Scale ASIC, the N9K-C9336C-FX2 delivers wire-rate forwarding across all 36 QSFP28 ports with 40 MB of system buffer to handle bursty, high-throughput workloads without performance degradation. The platform supports flexible breakout configurations — including 4x10G, 4x25G, 2x50G NRZ, and 1G/10G via QSA on eligible ports — making it equally effective as a high-density leaf node, spine switch, or aggregation layer device. A 4-core CPU, 24 GB of system memory, and a 128 GB SSD provide the compute headroom needed for advanced NX-OS features, real-time telemetry, and large routing tables.
At $4,950, the N9K-C9336C-FX2 delivers enterprise-grade 100G performance well below new list pricing, protecting your capital budget while giving your infrastructure a credible upgrade path from 1G/10G/40G to 25G/50G/100G. WhaleyComm has served 5,000+ enterprise customers over 25+ years — every unit ships with a Lifetime Warranty and a Certificate of Testing.

Ideal Use Cases
Leaf-and-Spine Data Center Fabric
The 9336C-FX2 is purpose-built for leaf or spine roles in modern data center fabrics, delivering wire-rate 100G forwarding and deep buffers that sustain performance under high east-west traffic loads.
Cloud-Scale and Hyperconverged Environments
The Cisco Cloud Scale ASIC and high-density QSFP28 port configuration make this switch well-suited for cloud-native, containerized, and heavily virtualized workloads that demand massive bandwidth and low latency.
High-Density 100G Aggregation
With 36 QSFP28 ports in a 1RU footprint, the 9336C-FX2 consolidates aggregation-layer connectivity at 40G or 100G without requiring a chassis-based solution.
Speed Migration Projects
Flexible breakout support and QSA compatibility allow teams to migrate server-edge connections from 1G or 10G to 25G, and aggregation links from 40G to 100G, using the same switch hardware throughout the transition.
Cisco ACI Fabric Deployment
The 9336C-FX2 is ACI-ready and integrates directly into Cisco Application Centric Infrastructure environments as a leaf or spine node, supporting policy-driven automation and centralized management.
Advanced Telemetry and Observability
Built-in support for real-time analytics and granular flow visibility enables proactive network operations, making this platform a strong fit for environments prioritizing streaming telemetry and rapid fault isolation.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
Every QSFP28 port supports 40G or 100G natively. Breakout cables and adapters enable 4x10G, 4x25G, and 2x50G NRZ configurations on eligible ports. Ports 7 through 32 also support 1G and 10G connectivity via a QSA adapter, allowing existing optics to remain in service during a phased migration.
Yes. The 9336C-FX2 is ACI-ready and supported as a leaf or spine node within a Cisco Application Centric Infrastructure fabric. It also operates under standard Cisco NX-OS for environments not using ACI.
Cisco NX-OS feature sets such as advanced Layer 3 routing, VXLAN, and MPLS may require separate software licenses from Cisco. WhaleyComm recommends confirming your required feature set with your Cisco account team before deployment. Our engineering team is also available at +1 214 607-4800 or sales@whaleycomm.com to assist.
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.
