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 100GbE fabric switching, professionally tested and ready to deploy.
This refurbished Juniper QFX5120-32C (MPN: QFX5120-32C-AFI) is a 1U, 32-port 100GbE switch that has been professionally tested, validated, and reset to factory defaults before shipment. Every port, power supply, and fan module is verified against Juniper's original specifications, giving you confidence that you are deploying hardware that performs identically to new. The AFI variant provides back-to-front airflow to match hot-aisle/cold-aisle cooling designs common in modern data centers.The QFX5120-32C is built for high-performance leaf-spine architectures, campus distribution, and cloud-edge fabrics. Its 32 QSFP28 ports deliver dense 100GbE connectivity in a compact footprint, while full EVPN-VXLAN support enables scalable overlay networking across your entire fabric. Running Junos OS, the platform shares a consistent operational model with the broader Juniper QFX, EX, and SRX portfolio, and supports automation via NETCONF, REST APIs, and streaming telemetry for integration into modern DevOps and NetOps workflows.
Purchasing refurbished from WhaleyComm delivers the same hardware reliability at a fraction of the new-unit cost. Backed by our Lifetime Warranty and ISO 9001-certified testing process, this is an enterprise-proven platform for organizations that need high-density 100GbE switching without the capital expense of new hardware.

Ideal Use Cases
Data Center Spine Layer
The QFX5120-32C's 32 × 100GbE QSFP28 ports and EVPN-VXLAN support make it a natural fit for spine roles in leaf-spine fabrics, providing high-bandwidth, low-latency interconnect for dozens of leaf switches.
Data Center Leaf Switch
Deploy as a leaf node in a scalable fabric, using EVPN-VXLAN overlays to extend Layer 2 segments across a routed underlay while maintaining clean traffic segmentation and automation-friendly operations.
Campus Core or Distribution
The compact 1U form factor and rich L2/L3 feature set make the QFX5120-32C well-suited for high-performance campus core or distribution roles where 100GbE uplinks and consistent Junos OS operations are required.
Cloud and Colocation Environments
Purpose-built for cloud-style networking, this platform supports the automation workflows, telemetry pipelines, and overlay protocols that colocation and private cloud operators depend on for scale-out operations.
High-Bandwidth Aggregation
Organizations consolidating multiple 10GbE or 25GbE server tiers benefit from the QFX5120-32C's 100GbE port density, allowing high-speed aggregation without requiring additional chassis-based hardware.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
The two SKUs are identical in port count and features but differ in airflow direction. The AFI model (this unit) moves air back-to-front, suited for hot-aisle exhaust configurations. The AFO model moves air front-to-back for cold-aisle intake designs. Confirm your data center's airflow convention before ordering.
Yes. The QFX5120-32C supports full EVPN-VXLAN overlays under Junos OS, making it ready for modern leaf-spine and cloud fabric deployments. The unit is reset to factory defaults, so licensing and configuration will need to be applied for your specific environment.
The unit ships with Junos OS pre-installed and reset to factory defaults. Advanced feature sets or software subscriptions may require separate Juniper licensing depending on your deployment requirements. Contact our engineering team at +1 214 607-4800 or sales@whaleycomm.com to discuss your specific needs.
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.
