Ubiquiti USW-WAN-RJ45 – UniFi WAN Switch RJ45 10 GbE Multi-WAN Switch
Overview
The Ubiquiti USW-WAN-RJ45 is a 1U rack-mount UniFi WAN switch designed to provide high-speed RJ45 connectivity between UniFi Gateways and ISP infrastructure. It provides three 10 GbE RJ45 ports and one 1 GbE RJ45 port for WAN connectivity and gateway interconnection.
The switch is designed for Shadow Mode High Availability deployments, allowing two compatible UniFi Gateways to connect to a single ISP connection. For deployments involving multiple ISPs, Ubiquiti specifies using an additional USW-WAN-RJ45 switch.
Technical Information
- Product Type: UniFi WAN Switch RJ45
- WAN Interfaces: 3 x 10 GbE RJ45
- Additional Ethernet Interface: 1 x 1 GbE RJ45
- Switching Capacity: 20 Gbps
- Total Non-Blocking Throughput: 10 Gbps
- Forwarding Rate: 15 Mpps
- Form Factor: 1U rack mount
- Power: Dual universal AC inputs with internal redundant power supplies
WAN Connectivity
The USW-WAN-RJ45 provides three 10 GbE RJ45 ports supporting 10G, 5G, 2.5G, 1G, and 100M Ethernet speeds. A separate 1 GbE RJ45 port supports 1G, 100M, and 10M operation.
This port configuration is intended for high-speed WAN and gateway connectivity without requiring SFP+ transceivers or fiber cabling for the 10 GbE connections.
High Availability and Redundancy
The USW-WAN-RJ45 is designed for UniFi Shadow Mode High Availability deployments, linking two compatible UniFi Gateways to a single ISP connection. It incorporates two AC inputs and two internal 36W AC/DC power supplies for power redundancy.
For multiple-ISP deployments, Ubiquiti specifies using an additional USW-WAN-RJ45 switch rather than relying on a single unit for multiple ISP connections.
Performance and Deployment
The switch provides 20 Gbps switching capacity, 10 Gbps total non-blocking throughput, and a 15 Mpps forwarding rate. Its 1U rack-mount form factor is suited to structured network racks and gateway/ISP handoff environments.
The metal enclosure and dual AC power architecture support installation in enterprise network infrastructure where redundant power inputs and high-speed RJ45 WAN connectivity are required.
Applications
- UniFi Shadow Mode High Availability gateway deployments
- 10 GbE RJ45 ISP connectivity
- Dual-gateway WAN infrastructure
- Enterprise network racks
- Multi-WAN infrastructure using multiple USW-WAN-RJ45 units
- High-speed RJ45 WAN aggregation between UniFi Gateways and ISP equipment
Key Features
- Three 10 GbE RJ45 ports supporting 10G, 5G, 2.5G, 1G, and 100M
- One additional 1 GbE RJ45 port supporting 1G, 100M, and 10M
- Designed to link two Shadow Mode High Availability UniFi Gateways to one ISP
- Dual universal AC inputs with two internal 36W AC/DC power supplies
- 1U rack-mount design with 20 Gbps switching capacity and 10 Gbps non-blocking throughput
DC Supplies Product Note
The USW-WAN-RJ45 is an active Ethernet WAN switch, not a DC power supply, UPS, PoE injector, or standalone router. It requires 100–240V AC input power and provides Ethernet switching for WAN and gateway connectivity. Routing, firewalling, ISP authentication, and other gateway functions remain dependent on the connected UniFi Gateway and network configuration.
