Ubiquiti Networks USW-WAN-RJ45 10 GbE WAN network switch

SKU CH-K8BC-6TF56 MPN USW-WAN-RJ45

10 GbE WAN switch links two Shadow Mode HA gateways to one ISP with three 10 GbE RJ45 ports, one 1 GbE RJ45 port, dual AC inputs and 10 Gbps non-blocking throughput

  • Links two HA gateways to one ISP via 10 GbE
  • Three 10 GbE RJ45 ports support multi-gig speeds
  • Dual AC inputs provide power redundancy
  • 20 Gbps switching capacity with 15 Mpps forwarding
  • 1U rack-mount form factor weighs 2.3 kg

Purpose and audience

The Ubiquiti USW-WAN-RJ45 is a 10 GbE WAN switch built to connect two Shadow Mode High Availability UniFi Gateways to a single ISP line. Network administrators managing redundant gateway clusters will use it to maintain uplink continuity without adding a second ISP circuit.

Redundancy and port mix

Dual internal 36 W AC power supplies accept 100240V AC at 50 or 60 Hz, providing automatic failover if one feed drops. The front panel supplies one 1 GbE RJ45 port plus three 10 GbE RJ45 ports that also negotiate at 5 Gbps, 2.5 Gbps, 1 Gbps and 100 Mbps, so the same chassis handles both the HA heartbeat and the high-speed WAN uplink.

Pre-install checks

Verify the rack has a free 1U slot and can carry 2.4 kg with brackets fitted. Confirm the site runs UniFi Network version 9.1.120 or later so the switch appears in the controller. Ensure two independent AC circuits are available for the redundant inputs and that the 18 W maximum draw fits the available power budget.

Questions about this item

What replacement is needed for the dual AC power supplies inside the USW-WAN-RJ45 after extended operation?

The switch uses two internal 36 W AC/DC power supplies; if one fails the other keeps the unit running and the faulty module can be swapped without tools.

Which throughput ceiling is reached first when the three 10 GbE RJ45 ports run at full speed continuously?

Total non-blocking throughput is 10 Gbps, so sustained line-rate traffic on all three 10 GbE ports will hit that aggregate limit before the 20 Gbps switching capacity is reached.

How much heat and power does the USW-WAN-RJ45 produce when operating 24/7 at maximum load?

Maximum power draw is 18 W, so heat output stays low and the dual 100-240 V AC inputs share the load without needing external cooling.
