Dell N3224T-ONF

Overview

The Dell N3224T-ONF is a Layer 3 network switch designed to deliver high-speed connectivity and robust port density for growing networks. It features twenty-four auto-sensing 1 Gigabit Ethernet RJ-45 ports for connecting desktops, printers, phones, or IoT devices, alongside four 10 Gigabit SFP+ uplinks that ensure smooth traffic flow to aggregation or core layers. Additionally, two 100 Gigabit QSFP28 ports provide direct links to modern spine or storage fabrics, enabling scalable bandwidth as network demands increase.

This switch is well suited for campus wiring closets, branch offices, and edge racks in small data centers. It can serve as a top-of-rack switch for servers or as an access switch for office floors and classrooms. Its Layer 3 routing capabilities help keep east-west traffic local, reducing latency for collaboration tools, virtual desktops, and real-time analytics.

Connectivity and compatibility

This switch offers versatile connectivity options to fit into various network environments. The 24 RJ-45 ports accommodate standard Ethernet devices, while the 10G SFP+ uplinks provide fiber or direct attach cable connections to higher-tier switches or servers. The 100G QSFP28 ports enable direct integration with high-performance spine switches or storage fabrics, making it a flexible choice for evolving network architectures.

• Supports VLANs for traffic segmentation and enhanced security
• VXLAN support extends Layer 2 networks across multiple racks or sites
• Compatible with common network orchestration tools through REST APIs

Performance and reliability

Designed for continuous operation, this switch includes hardware features that maintain uptime and simplify maintenance. The front-to-back airflow aligns with typical data center cooling strategies, ensuring efficient heat dissipation within a standard 1U rack space. Redundant power supplies and fans can be replaced without interrupting network services, which is critical for environments where downtime is not an option.

Ideal uses and environments

The Dell N3224T-ONF fits well in environments that require a balance of port density, speed, and advanced Layer 3 features. It is a strong choice for campus networks, branch offices, and small data centers that need reliable access or top-of-rack switching. Teams managing virtualized workloads or real-time collaboration tools will benefit from its low-latency routing and traffic segmentation capabilities.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
