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 Cisco N9K-C93180YC-EX is a 1-rack-unit (1RU) Nexus 9300-EX Series data center switch delivering enterprise-grade performance at a fraction of new-unit cost. It ships reset to factory defaults and verified against Cisco's published specifications. The N9K-C93180YC-EX provides 48 x 1/10/25G SFP+ downlink ports and 6 x 40/100G QSFP28 uplink ports, making it one of the most port-density-efficient 1RU switches in its class for high-speed server and spine connectivity.Built on Cisco's Cloud Scale ASIC, the 93180YC-EX delivers 3.6 Tbps of switching capacity and sub-1-microsecond latency — purpose-built for latency-sensitive workloads including high-frequency trading, AI/ML training clusters, and large-scale virtualization fabrics. The switch supports both NX-OS standalone mode and Cisco ACI mode, providing deployment flexibility whether you are running a traditional Nexus fabric or a full policy-driven ACI environment. Key features include VXLAN with BGP EVPN, Virtual PortChannel (vPC), MACsec, line-rate Cisco Tetration Analytics telemetry, ISSU (In-Service Software Upgrade), and a 40 MB packet buffer to absorb traffic bursts without drops. The 48 downlink ports are fully flexible, configurable at 1G, 10G, or 25G — protecting your existing cabling investment while enabling a clean migration path to 25G server connectivity.
WhaleyComm sources, tests, and certifies every unit through our ISO 9001-certified refurbishment process. Each N9K-C93180YC-EX is fully powered on, port-by-port validated, firmware-verified, and reset to factory defaults before shipment. Backed by our Lifetime Warranty, this unit represents an exceptional value for enterprise data center, campus core, and cloud-scale leaf/spine deployments — delivering Cisco's flagship 25G ToR performance at a significant savings over new list pricing.

Ideal Use Cases
Data Center Leaf Switch (25G ToR)
The N9K-C93180YC-EX is purpose-built as a top-of-rack leaf switch, connecting 48 servers at 1/10/25G while uplinks carry 100G traffic to spine switches — ideal for modern leaf-spine fabrics.
Cisco ACI Fabric Leaf Node
Fully compatible with Cisco ACI mode, this switch can serve as an ACI leaf node delivering automated, policy-driven workload connectivity across physical and virtual environments.
Cloud-Scale and Hyperconverged Infrastructure (HCI)
With 3.6 Tbps of non-blocking throughput and sub-1-microsecond latency, this switch is well-suited for VMware vSAN, Nutanix, or Cisco HyperFlex HCI deployments requiring consistent low-latency storage and compute traffic.
Campus Core or Aggregation Upgrade
Organizations upgrading from 10G core infrastructure can leverage the flexible 1/10/25G downlinks and 40/100G uplinks to incrementally migrate without replacing existing structured cabling.
High-Frequency Trading and Financial Services
Sub-1-microsecond cut-through latency and line-rate wire-speed forwarding make this switch a strong fit for trading floors, risk analytics platforms, and financial data centers where latency directly impacts revenue.
Network Refresh / CapEx Reduction
Organizations seeking to modernize their data center switching infrastructure without new-unit pricing can deploy this refurbished N9K-C93180YC-EX and achieve full Cisco performance at a significant cost reduction.
