Product overview

The Dell Networking N2048 is a high-performance 1RU Layer 3 Gigabit Ethernet switch designed for enterprise campus and branch networks. It features 48 fixed 10/100/1000Base-T RJ-45 ports delivering line-rate performance, two integrated 10GbE SFP+ uplink ports for high-speed connectivity to aggregation layers, and two rear SAS stacking ports enabling stacks of up to 12 switches managed as a single logical unit with non-stop forwarding. With 220Gbps switching capacity (full duplex) and 164Mpps forwarding rate, it handles demanding traffic loads without blocking. Energy-efficient design includes 80PLUS-certified integrated power supply, Energy-Efficient Ethernet, and operation up to 113°F (45°C) to reduce cooling costs. Supports advanced Layer 2+/IPv4/IPv6 routing, MLAG for redundancy, RPVST+ interoperability, and USB auto-configuration. PoE+ capable models power devices like APs and VoIP phones up to 30.8W per port. Ideal for access layer deployments requiring scalability, reliability, and low TCO in data centers, IDFs, and wiring closets.

Frequently asked questions

What is the switching capacity and forwarding rate of Dell N2048?

Dell N2048 provides 220Gbps full-duplex switching capacity and 164Mpps forwarding rate. This non-blocking architecture delivers line-rate performance across 48 GbE ports and 2x10GbE SFP+ uplinks, ideal for bandwidth-intensive campus access deployments with unexpected traffic spikes.

Does the N2048 support PoE and what is the power budget?

N2048P variant supports PoE+ on all 48 ports up to 30.8W per port with optional external power supply. Integrated 1000W PSU in base model; PoE models power APs, cameras, and VoIP without separate cabling, simplifying installations in legacy buildings.

How does stacking work on the Dell N2048?

Rear SAS stacking ports enable up to 12 switches in a ring topology with 84Gbps stack bandwidth. Supports non-stop forwarding, fast failover, and single IP management for up to 576 GbE ports, providing high availability without spanning tree.

What management options are available for N2048?

Features common CLI, web GUI, USB auto-configuration for rapid deployment, and Dell OS6. Supports SNMP, RMON, sFlow, and OpenManage Network Manager for enterprise-scale monitoring and mirrored config rollout across stacks.

Is the N2048 compatible with Cisco networks?

Supports RPVST+ and CDP for interoperability with Cisco devices. MLAG enables active/active redundancy without loops, plus open-standard protocols like 802.1x, TACACS+, and RADIUS for secure multivendor integration.

What are the environmental operating specs?

Operates 0-45°C (32-113°F) with Dell Fresh Air compliance, redundant fans, and 80PLUS power supply. Energy-Efficient Ethernet and low-power PHYs cut consumption on idle links, lowering TCO in high-density racks.
