Powered Entirely Over PoE++
No power brick at the switch — the USW-Flex is powered by a single PoE++ uplink or a 60 W PoE adapter, so you can place it almost anywhere a network cable reaches.
46 W of PoE+ Output
When fed by a PoE++ source, four GbE ports deliver up to 46 W total (25 W max per port), enough to run UniFi cameras, access points, and other PoE devices downstream.
Outdoor-Ready Design
A rugged polycarbonate enclosure operates from −40°C to 65°C and 5–95% humidity, making it suitable for sheltered outdoor and demanding Australian environments.
Full Layer 2 Management
VLANs, port isolation, port mirroring, flow control, jumbo frames, and egress rate limiting — all configured through the UniFi Network application with no per-device licensing.
Flexible Mounting
Compact 122.5 × 107.1 mm form factor mounts on a desk, wall, or pole, letting you bring switching and PoE exactly where it's needed.
NDAA Compliant
Fully NDAA Section 889 compliant for government, defence, and security-sensitive installations where supply-chain integrity is a requirement.
UniFi Switch Flex (USW-Flex)
The 5-port outdoor-ready managed PoE++ switch.
Mounting Hardware
Brackets and screws for desk, wall, or pole installation.
Documentation
Quick-start guide and installation instructions.
Not Included
A PoE++ switch or 60 W PoE adapter is required to power the unit and unlock the full 46 W PoE budget (sold separately).
How is the USW-Flex powered?
Entirely over its PoE input port. Use a PoE++ switch or a 60 W PoE adapter to get the full 46 W of downstream PoE; PoE+ and standard PoE inputs work too, with smaller budgets.
How much PoE can it deliver to my devices?
Up to 46 W total across four PoE+ ports (25 W max per port) when fed by a PoE++ source — enough for UniFi cameras, access points, and IoT devices.
Can it be used outdoors in Australia?
Yes. It's outdoor-ready with a polycarbonate enclosure rated from −40°C to 65°C and 5–95% humidity, suiting sheltered outdoor and harsh Australian conditions.
Do I need a controller to manage it?
Yes. The USW-Flex is managed through the UniFi Network application running on a UniFi Cloud Gateway, Dream Machine, or Cloud Key — there are no per-device licence fees.
Is the USW-Flex NDAA compliant?
Yes. Ubiquiti is a US-based manufacturer and the USW-Flex is NDAA Section 889 compliant — suitable for government and security-sensitive sites.
