ADVANCED FEATURES :

High-Performance Switching Fabric:

The N3048ET-ON is designed with a non-blocking switching architecture, delivering 260 Gbps of switching capacity and 193 Mpps forwarding rate. This ensures wire-speed Layer 2 and Layer 3 performance across all ports, supporting enterprise-grade workloads, virtualized environments, and high-density campus deployments. The switch’s large MAC address table (32,000 entries) and support for thousands of VLANs allow for scalable, high-speed connectivity and smooth traffic flow, even in multi-tenant or highly segmented network topologies. Advanced routing protocols such as VRF-lite, OSPF, RIP, and static routes ensure intelligent traffic distribution and low-latency forwarding across all network layers.

Stacking and Multi-Chassis Link Aggregation (MLAG):

The N3048ET-ON supports up to 8-unit stacking (OS 6.5.1 and later), providing simplified centralized management and horizontally scalable network growth. Stacking allows the interconnected switches to operate as a single logical unit, making network administration more efficient. Additionally, MLAG enables active-active redundancy, ensuring high availability and uninterrupted connectivity across critical links. Traffic can be load-balanced across multiple switches in the stack, eliminating single points of failure and providing seamless failover during maintenance or unexpected outages.

Layer 3 Routing and Segmentation:

Advanced Layer 3 functionality enables the N3048ET-ON to segment traffic efficiently while supporting multi-protocol routing. It includes VRF-lite for network virtualization, static routing for predictable paths, and dynamic routing with OSPF and RIP to adapt to changing network conditions. These capabilities make the switch ideal for multi-tenant environments, departmental networks, or segmented enterprise deployments, providing both operational flexibility and network security.

Energy Efficiency and Fresh-Air Operation:

The switch is built with Energy Efficient Ethernet (EEE), reducing power consumption during periods of low network activity without compromising performance. Its fresh-air design compliance allows operation in standard office, wiring closet, or data center environments without requiring specialized cooling infrastructure. This design lowers operational costs, increases deployment flexibility, and simplifies installation in diverse physical environments.

Redundant, Serviceable Hardware:

High availability is supported through dual 200W 80PLUS-certified hot-swappable power supplies and four hot-swappable variable-speed fans. The modular design ensures that maintenance, replacements, or upgrades can be performed without service disruption, providing continuous network uptime for mission-critical applications. This robust hardware design ensures resilience against hardware failures while enabling quick field serviceability.

Open Networking Ready:

The N3048ET-ON is ONIE-compatible, enabling zero-touch installation of various network operating systems such as Dell SmartFabric OS10 or SONiC. This allows organizations to leverage open networking principles, deploy customized network solutions, and adopt future-ready architectures. Network administrators gain flexibility to adapt to evolving network requirements without being locked into a single proprietary OS.

Comprehensive Security:

Security is integrated at multiple layers, including role-based access control (RBAC), Layer 2–Layer 4 ACLs, 802.1X authentication, and MAC-based authentication, ensuring that only authorized devices and users can access the network. Protection against common attacks is provided by DHCP snooping, Dynamic ARP Inspection (DAI), and IP Source Guard, preventing spoofing, man-in-the-middle attacks, and unauthorized traffic injection. These features make the N3048ET-ON suitable for sensitive enterprise environments, campuses, and multi-tenant deployments.

Automation and Monitoring:

The switch supports advanced management and automation features to reduce operational overhead. REST APIs, sFlow, RMON, and telemetry enable administrators to monitor traffic trends, port utilization, and network performance in real-time. Zero-Touch Provisioning (ZTP) automates initial switch configuration, reducing manual setup and deployment time. With these capabilities, IT teams can proactively detect bottlenecks, troubleshoot issues quickly, and maintain optimal network performance across large-scale deployments.

Scalability and Future-Proof Architecture:

The N3048ET-ON is designed for growing enterprise networks. Its support for stacking, MLAG, VRF-lite, and dynamic routing protocols ensures that network expansion and increasing traffic demands can be handled seamlessly. Future-ready features like open networking support, large VLAN scalability, and robust telemetry prepare the switch to meet evolving enterprise, campus, and distributed network requirements for years to come.
