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.

Enterprise-grade 10GbE top-of-rack density. Professionally tested. Backed by 25 years of enterprise trust.

This refurbished Cisco N3K-C3172TQ-10GT is a 1RU Nexus 3172TQ top-of-rack switch delivering 48 10GBASE-T RJ-45 ports and 6 QSFP+ uplink ports, each capable of operating at 4 x 10 Gigabit Ethernet or 40 Gigabit Ethernet. Every unit is professionally tested, reset to factory defaults, and ships inspection-verified through WhaleyComm's ISO 9001-certified process. Dual AC power supplies are included for redundant operation.

Built on Cisco's Nexus 3100 platform, the N3K-C3172TQ-10GT delivers 1.4 Tbps of switching capacity and a forwarding rate of up to 1 billion packets per second with line-rate Layer 2 and Layer 3 throughput across all ports. Running Cisco NX-OS, the switch supports virtual port-channel (vPC), 64-way ECMP routing, jumbo frames up to 9216 bytes, up to 4096 VLANs, and a MAC address table of 288,000 entries. Both port-side exhaust and port-side intake airflow configurations are supported, making it straightforward to slot into hot-aisle or cold-aisle data center designs.

At $1,599, this unit represents substantial savings versus new list price while delivering the same line-rate performance trusted by enterprise data centers worldwide. WhaleyComm's 25+ years of experience and 5,000+ enterprise customers mean you receive not just hardware, but verified reliability and a Lifetime Warranty that new-channel vendors cannot match.

Ideal Use Cases
Data Center Top-of-Rack (ToR) Deployment
The N3K-C3172TQ-10GT is purpose-built as a top-of-rack switch, delivering line-rate 10GbE to servers while aggregating traffic upstream over 40GbE QSFP+ uplinks — ideal for high-density compute rows.
Copper Cabling Infrastructure Reuse
The 48 10GBASE-T RJ-45 ports allow organizations to migrate servers from 1 Gbps to 10 Gbps without replacing existing copper cabling, protecting prior infrastructure investment.
High-Performance Layer 2 and Layer 3 Switching
With 1.4 Tbps switching capacity and full Layer 2/3 line-rate performance, this switch handles demanding east-west and north-south traffic patterns common in modern virtualized and containerized data centers.
vPC and Redundant Fabric Designs
Native vPC support eliminates Spanning Tree Protocol dependencies, enabling Layer 2 multipathing and fully utilized bisectional bandwidth for resilient dual-homed server and fabric designs.
Budget-Conscious Enterprise Refresh
Organizations refreshing aging access or ToR infrastructure gain proven Cisco Nexus performance at a fraction of new-hardware cost, with WhaleyComm's Lifetime Warranty eliminating residual risk.
NX-OS Standardized Environments
Running Cisco NX-OS, the switch integrates directly into existing Nexus management workflows, automation toolchains, and monitoring stacks without retraining network operations teams.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
Yes. The N3K-C3172TQ-10GT supports both port-side exhaust (front-to-back) and port-side intake (back-to-front) airflow configurations. This gives data center operators the flexibility to align the switch with hot-aisle or cold-aisle containment designs without additional hardware changes.
Yes. Each of the 6 QSFP+ ports supports either a single 40 Gigabit Ethernet connection or 4 x 10 Gigabit Ethernet connections via breakout cable. This gives network architects flexibility when designing uplink or spine interconnect topologies.
The N3K-C3172TQ-10GT ships with all 48 10GBASE-T ports active by default. Note that advanced Layer 3 features under certain NX-OS operating modes may require additional software licensing. Contact our engineering team at +1 214 607-4800 or sales@whaleycomm.com for licensing guidance specific to your environment.
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.
