What is the switching capacity and forwarding rate of Dell N3048?

Dell N3048 provides 260Gbps full-duplex switching capacity and 193Mpps forwarding rate, enabling non-blocking Layer 2/3 performance across 48x 1GbE and 2x 10GbE ports. This supports high-throughput environments like data centers with line-rate routing and low latency of ~3.7μs.

Does the N3048 support stacking and what is the bandwidth?

Yes, it features 2x rear stacking ports at 21Gbps each, delivering up to 84Gbps full-duplex stacking bandwidth. Up to 6 units can stack into a single logical switch, simplifying management and enhancing redundancy for enterprise access layers.

What management interfaces are available on N3048?

Management includes Web GUI, CLI, and SNMP for configuration. It runs Dell OS6 by default, supporting standards-based features like LLDP, STP, and QoS with 8 queues per port, ideal for automated enterprise deployments.

What are the port configurations on Dell N3048?

48x RJ45 10/100/1000Mb auto-sensing ports, 2x 10GbE SFP+ fixed uplinks, 2x GbE combo ports (RJ45/SFP). This mix offers flexibility for copper/fiber connections in access-aggregation roles.

Is the N3048 suitable for data center top-of-rack?

Yes, with 260Gbps capacity, 10GbE uplinks, IO-to-PSU airflow, and 1RU form factor. It excels in edge ToR roles for 1GbE servers, providing low-latency switching and stacking for spine connectivity.

What environmental specs does N3048 support?

Operates 0°C to 45°C, 5-85% RH non-condensing, up to 10,000ft altitude. Single 200W AC PSU with 87W max consumption ensures efficient cooling in standard racks.

Product overview

The Dell Networking N3048 is a high-performance, 1RU Layer 3 Ethernet switch designed for enterprise access, aggregation, and data center edge deployments. It features 48x 10/100/1000BASE-T RJ45 auto-sensing ports, 2x dedicated 10GbE SFP+ uplink ports, and 2x GbE combo ports (copper/fiber) for flexible connectivity. With a 260Gbps switching capacity and 193Mpps forwarding rate, it ensures non-blocking performance across all ports. Stacking capability via 2x rear ports (21Gbps each, up to 84Gbps full-duplex) allows up to 6 units in a stack for scalable topologies. Key features include support for 64K MAC addresses, 4,000 VLANs, MSTP (64 instances), IGMP snooping, 8 QoS queues per port, jumbo frames up to 9,000 bytes, and line-rate L2/L3 routing. Management options encompass Web GUI, CLI, and SNMP. Efficient IO-to-PSU airflow, single hot-swappable 200W AC PSU, and operating range of 0-45°C make it reliable for SMB to enterprise environments. Ideal for modernizing campus networks with high port density and low latency (~3.7μs L2).
