UniFi WAN Switch RJ45
3x 10G RJ45Redundant PowerShadow Mode HA
The Ubiquiti UniFi WAN Switch RJ45 (USW-WAN-RJ45) is a purpose-built 1U switch for high-availability gateway deployments, offering three 10GbE RJ45 ports (10G/5G/2.5G/1G/100M auto-negotiating) plus one 1GbE management port. Two of the 10G ports typically connect a primary and redundant UniFi Cloud Gateway running in Shadow mode, while the third takes the incoming ISP line, giving a resilient WAN edge without a single point of failure. A 1+1 redundant dual AC power supply and 20Gbps switching capacity round out a design built for mission-critical uptime. Typically in stock with fast delivery across Cyprus.
Compatibility note: Shadow mode HA failover requires two compatible UniFi Cloud Gateways — this switch on its own does not provide gateway redundancy, it is the interconnect that enables it.
Best For
✓ Redundant/HA UniFi gateway deployments
✓ Sites needing zero-downtime WAN failover
✓ 10G copper WAN aggregation
✓ Mission-critical office or datacenter edges
✓ Dual power feed environments
✓ UniFi Network managed WAN infrastructure
Key Features
3x 10G RJ45 + 1x 1G Management
Multi-gig copper ports handle primary/redundant gateway links and the ISP uplink, plus a dedicated 1G management port.
Shadow Mode Gateway Failover
Designed to interconnect two UniFi Cloud Gateways running in Shadow mode HA for automatic WAN failover.
1+1 Redundant Power
Dual AC inputs mean the switch keeps running even if one power feed or supply fails.

Frequently Asked Questions
Does this switch provide gateway redundancy by itself?
No, it is the interconnect for two UniFi Cloud Gateways running Shadow mode HA — the gateways provide the actual failover.
What is the 1G port used for?
It is a dedicated management port, separate from the three 10G WAN/uplink ports.
Is dual power required?
Not required, but recommended for full redundancy — the switch operates on a single AC feed if a second is unavailable.
Singular Expert Insight
Pair this switch with two compatible UniFi Cloud Gateways in Shadow mode to get real WAN failover — on its own with a single gateway it functions as a standard multi-gig switch.
Buyer's Guide
Buy it if: you are deploying redundant UniFi gateways and need a 10G copper interconnect switch.
Skip it if: you have fiber SFP+ infrastructure instead of copper — consider the USW-WAN SFP+ variant.
Also consider: USW-WAN for an SFP+ fiber-based alternative.
