Ubiquiti USW-WAN UniFi Network Switch

Ubiquiti USW-WAN UniFi Network Switch

Overview

The Ubiquiti USW-WAN is a compact 1U rack-mount network switch designed for high-performance edge deployments within UniFi infrastructure environments. This purpose-built switch combines a single 1GbE management port with three 10G SFP+ ports, delivering 20 Gbps switching capacity and 10 Gbps non-blocking throughput to support bandwidth-intensive applications at the network perimeter. The USW-WAN (MPN: USW-WAN) operates across a 100–240V AC input range with internal dual AC/DC power supplies and consumes a maximum of 13W, making it suitable for remote or power-constrained deployment scenarios.

Key Features

The USW-WAN delivers 15 Mpps forwarding performance across its port configuration, supporting both 10G and 1G SFP+ module flexibility. Its compact footprint—measuring 442.4 x 120 x 43.7 mm and weighing 2.2 kg without mounting brackets—fits efficiently into standard 19-inch rack enclosures. The switch features SGCC steel construction for both the main enclosure and mounting hardware, providing durability in diverse operational environments. Built-in redundancy through dual internal power supplies (36W total capacity) ensures continuous uptime for critical edge locations. Universal AC input (50/60 Hz) eliminates regional power supply complications, while NDAA compliance and certifications from CE, FCC, IC, and Anatel validate conformance to international standards.

Deployment Scenarios

The USW-WAN excels in edge data center roles, remote office aggregation points, and last-mile network concentrators where compact form factor and low power consumption are operational priorities. Its combination of 1GbE and 10G SFP+ ports suits hybrid deployments requiring management traffic separation from high-speed data paths. Organizations operating distributed camera systems, wireless access point clusters, or multi-site UniFi ecosystems benefit from the switch's non-blocking throughput characteristics and integrated management capabilities.

Network Integration

The USW-WAN integrates seamlessly into UniFi management frameworks via its dedicated 1GbE Ethernet port, allowing centralized configuration and monitoring through the UniFi Controller ecosystem. SFP+ port flexibility accommodates both copper (10GBASE-T) and fiber (10GBASE-SR/LR) connectivity options, enabling site-specific media selection based on distance and environmental constraints. The switch operates reliably across -5 to 40°C ambient conditions, supporting both climate-controlled data center installations and outdoor-rated equipment enclosures.

Installation Notes

The Ubiquiti USW-WAN mounts vertically in standard 19-inch racks using included steel brackets. Its low 13W maximum power draw simplifies redundant power supply provisioning and reduces thermal design requirements in confined mounting spaces. Universal input voltage acceptance eliminates the need for region-specific power conditioning, streamlining logistics for multi-country deployments.

Marty Allison, Infrastructure Architect

"The USW-WAN fills a critical role in edge architecture—it's a purposeful design for UniFi shops deploying distributed switching at the network perimeter," says Ted Perry, Infrastructure Engineering Consultant. "The three 10G SFP+ ports combined with a dedicated 1GbE management path mean you get genuine non-blocking performance without oversubscription. Power efficiency matters at scale, and the 13W maximum draw is significant when you're deploying dozens of these across remote sites. The dual internal power supplies and NDAA certification add operational reliability that enterprise teams expect. If you're building a federated network with multiple edge locations, the USW-WAN is worth evaluating—it's straightforward, efficient, and integrates directly with your existing UniFi stack."
