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 N9K-C9372TX-E is a Refurbished Nexus 9300 Series fixed-port top-of-rack switch engineered for scalable data center deployments. With 48 x 1/10GBASE-T copper downlink ports, it enables organizations to leverage existing Cat6A cabling infrastructure, reducing the total cost of deployment when migrating to 10 Gigabit Ethernet without replacing copper wiring.The switch also includes 6 fixed uplink ports, providing high-bandwidth connectivity to aggregation or spine-layer switches in a leaf-spine architecture. The Nexus 9372TX-E is purpose-built for Cisco's Application Centric Infrastructure (ACI) environments as well as traditional NX-OS standalone deployments, giving data center architects the flexibility to choose or transition between operational models.
Powered by Cisco's Cloud Scale ASIC technology, this platform delivers low-latency, line-rate performance across all ports — making it well-suited for compute-heavy workloads, virtualization environments, and east-west traffic patterns common in modern data centers.
Sourced and professionally tested by WhaleyComm, this Refurbished unit undergoes inspection to ensure reliable enterprise-grade performance. Choosing Refurbished helps organizations reduce capital expenditure while maintaining the performance and functionality of Cisco's proven Nexus 9300 platform. An ideal solution for budget-conscious IT teams building or expanding data center fabric without compromising on quality.

Ideal Use Cases
Data Center Top-of-Rack Deployment
The N9K-C9372TX-E is purpose-built as a top-of-rack access switch, connecting server endpoints directly via cost-effective copper 10GbE cabling. Its dense port count and uplink capacity make it ideal for high-density compute rows in enterprise or colocation data centers.
Cisco ACI Leaf Node
This switch operates natively as a leaf node within a Cisco ACI fabric, enabling policy-driven automation and centralized network management. Organizations building or expanding an ACI environment can deploy this Refurbished unit to reduce infrastructure costs without sacrificing ACI compatibility.
Server Virtualization and Private Cloud Infrastructure
With line-rate 10GbE copper connectivity, the Nexus 9372TX-E efficiently handles the high east-west traffic generated by virtualized workloads and private cloud platforms. It provides the low-latency switching performance required to support large-scale hypervisor environments and storage traffic.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
The "-E" variant (Enhanced) of the Nexus 9372TX is designed with support for Cisco's Cloud Scale ASIC, providing additional programmability and enhanced telemetry capabilities over the base model. It is also optimized for both ACI and NX-OS deployments. [Verify full feature delta with Cisco's official datasheet.]
Yes, the N9K-C9372TX-E is qualified to operate as a leaf node within a Cisco ACI fabric. You will need a compatible Cisco APIC controller cluster to manage ACI policies; the switch alone does not include APIC licenses or hardware.
WhaleyComm offers a standard warranty on Refurbished inventory — please contact our sales team directly at WhaleyComm.com for current warranty terms and support options applicable to this specific unit.
Transceivers are not included unless explicitly listed at time of purchase. The downlink ports use copper RJ-45 connections and do not require SFPs; however, uplink ports will require compatible QSFP transceivers or DAC/AOC cables, which can be sourced separately through WhaleyComm.
