Product overview

The Dell Networking N1548 is a high-performance 1RU Layer 3 Lite managed switch designed for medium to large enterprise environments, upgrading legacy 10/100 networks to Gigabit Ethernet with PoE+ support. It features 48x auto-sensing 10/100/1000Mb RJ45 ports delivering up to 30.8W PoE+ per port, four dedicated 10GbE SFP+ uplink ports (two configurable for stacking), and a 176Gbps full-duplex switching fabric with 164Mpps forwarding rate for non-blocking wire-speed performance. Key capabilities include 512 VLANs, 16K MAC addresses, 256 static/dynamic IPv4 routes, QoS with 8 priority queues per port, link aggregation (64 LAGs), and ACLs with up to 2048 rules. Stacking supports up to four units over 40Gbps full-duplex at 100m distance. Ideal for access layer deployments powering IP phones, cameras, and wireless APs while providing high-speed uplinks to aggregation. Energy-efficient with redundant fans, dual firmware, and 80+ efficient PSU options.

Frequently asked questions

What is the switching capacity and forwarding rate of the Dell N1548?

The Dell N1548 provides 176Gbps full-duplex switching capacity and 164Mpps forwarding rate, enabling non-blocking Layer 2/3 performance across all 48x 1GbE and 4x 10GbE ports. This supports high-density access with wire-speed forwarding for east-west traffic in enterprise networks.

Does the N1548 support PoE+ and what is the power budget?

Yes, it features 48x 10/100/1000Mb RJ45 PoE+ ports delivering up to 30.8W per port. Models like N1548P include a 600W PSU for full PoE budget, powering APs, cameras, and phones without separate cabling in access deployments.

What stacking capabilities does the N1548 offer?

Supports stacking up to four units using two of the four 10GbE SFP+ ports at 40Gbps full-duplex over 100m distance. This creates a single logical switch with unified management, ideal for redundant access layer designs.

What Layer 3 features are available on the N1548?

Layer 3 Lite includes static/dynamic routing (256 IPv4/128 IPv6), 512 VLANs, RIP (128 interfaces), VLAN routing (128 interfaces), and ACLs (2048 rules max). Supports protocol-based VLANs, ARP (2048 IPv4), and QoS with 8 queues per port.

What are the environmental operating conditions?

Operates from 0° to 45°C (32° to 113°F) at up to 95% humidity. Features redundant variable-speed fans with I/O to PSU airflow, 80+ efficient PSU, and max power draw of 1704W (PoE model) with 5824 BTU/hr thermal output.

What transceivers are compatible with the SFP+ ports?

Supports SFP+ 10GbE SR (850nm, 300m), LR (1310nm, 10km), ER (1550nm, 40km), and copper twinax cables. Downward compatible with 1GbE SFP optics like SX, LX, ZX for flexible 1/10GbE uplinks.
