Ubiquiti USW-WAN-RJ45 UniFi Network Switch

Ubiquiti USW-WAN-RJ45 UniFi Network Switch

Overview

The Ubiquiti USW-WAN-RJ45 is a compact 1U rack-mount switch designed for unified network infrastructure deployments. Built on Ubiquiti's UniFi ecosystem, this model consolidates WAN aggregation and local switching in a single device, delivering 20 Gbps switching capacity with a 10 Gbps non-blocking architecture. The unit combines one 1 GbE port with three 10 GbE ports, making it suitable for environments requiring high-speed uplinks without excess port density. With a maximum power consumption of just 18W, the USW-WAN-RJ45 operates efficiently across standard AC power inputs (100–240V, 50/60 Hz) and fits seamlessly into standard 19-inch rack enclosures.

Key Features

The forwarding rate of 15 Mpps ensures consistent performance under sustained traffic loads. Ethernet-based management simplifies network integration without requiring dedicated out-of-band connectivity. The device is housed in SGCC steel construction with matching steel mounting brackets, delivering durability in distributed and campus environments. Operating temperature range of -5 to 40°C accommodates both indoor server rooms and outdoor cabinet deployments. The Ubiquiti USW-WAN-RJ45 holds certifications including CE, FCC, IC, and Anatel compliance, with full NDAA compliance for U.S. government and defense procurement requirements.

Deployment Scenarios

This switch is well-suited for multi-site deployments where remote locations require aggregation of 10 GbE uplinks to a central backbone. Educational institutions often deploy it in building distribution frames to consolidate departmental access layer switches. Managed service providers use the model in customer sites requiring compact, low-power WAN termination without full core-layer functionality. The 1U form factor and minimal footprint (442.4 × 120 × 43.7 mm) make it ideal for space-constrained cabinets in branch offices or small data centers.

Network Integration

The port configuration—one 1 GbE management/failover port and three 10 GbE data ports—allows flexible topology design. The single gigabit interface can serve as a resilient out-of-band management path while the 10 GbE ports carry production traffic, or all ports can operate in a unified switching fabric. UniFi network visibility and controller integration simplify monitoring and provisioning across distributed sites. The 20 Gbps switching capacity provides sufficient headroom for full-line-rate throughput across most port combinations.

Installation Notes

The unit weighs 2.3 kg without mounting brackets and includes redundant AC power inputs, each fed by a 36W internal AC/DC supply. This redundancy eliminates single points of failure in power delivery. Standard rack mounting hardware is provided. The low thermal profile and passive airflow design reduce mechanical cooling demands in remote or outdoor deployments. No special cabling or media conversion is required for standard RJ45 Ethernet connections.

Marty Allison, Infrastructure Architect

"The USW-WAN-RJ45 fills a specific need for organizations moving away from traditional modular chassis at the branch level. The three 10 GbE ports give you real bandwidth for application traffic or uplink redundancy, while that single gigabit port handles management without chewing up data bandwidth. I've deployed it in twelve customer sites over the past year—works particularly well where you're consolidating multiple older access switches and need sub-100W power budgets. The NDAA compliance was a blocker-remover for three federal integrations. Not a core switch, but as a WAN aggregator in a UniFi fabric, it's reliable and quiet."
