Flex (USW-Flex)

The USW-Flex (UniFi Switch Flex) is an ultra-compact, indoor/outdoor Layer 2 managed PoE switch purpose-built for flexible deployment across East Africa's most challenging network environments — from outdoor campus installations and rooftop access point deployments to remote location switching and harsh industrial environments. Measuring just 122.5 × 107.1 × 28 mm (4.8 × 4.2 × 1.1") and weighing only 230 g (8.1 oz), the USW-Flex supports compact desktop, wall, and pole mounting and is self-powered entirely via its (1) GbE PoE++ input port — requiring no separate power adapter or power outlet at the deployment location. Requires UniFi Network version 5.10.3 and later.

The USW-Flex provides (4) GbE RJ45 PoE+ output ports (1G/100M/10M) at up to 25W per port — powering access points, IP cameras, VoIP phones, and IoT devices in outdoor and remote locations. Total PoE availability varies by input power method:

• 46W with PoE++ or 60W PoE adapter input
• 20W with PoE+ input
• 8W with PoE input

Switching capacity of 10 Gbps with 5 Gbps non-blocking throughput and 7 Mpps forwarding rate delivers wire-speed performance across all five ports. The outdoor-ready design with an operating temperature range of -40°C to 65°C (-40°F to 149°F) — one of the widest ranges of any UniFi switch — and 5–95% non-condensing humidity tolerance handles the full spectrum of East African outdoor environments from coastal humidity to highland cold. ±16kV ESD protection on all air and contact ports safeguards the switch and connected equipment against electrical surges from lightning and static discharge — critical for exposed outdoor East African deployments.

The Layer 2 feature set includes:

• Egress rate limiting for bandwidth management per port
• Flow control for congestion management
• Port isolation for client and device separation
• Port mirroring for network monitoring and troubleshooting
• Jumbo frames for large payload support

Additional specifications:

• Max. power consumption: 5W excluding PoE output / 51W including PoE output
• Heat dissipation: 17.1 BTU/hr excluding PoE output
• Supported voltage range: 50–57V PoE
• Management via Ethernet
• Operating temperature: -40°C to 55°C at 46W PoE output / -40°C to 65°C at 25W PoE output
• CE, FCC, IC, and Anatel certified, fully NDAA compliant

Ideal for outdoor access point deployments, rooftop installations, remote location networks, distributed campus switching, pole-mount environments, harsh industrial environments, and any indoor or outdoor deployment across Kenya, Uganda, Tanzania, Rwanda, and the wider East and Central Africa region requiring 5-port Gigabit PoE switching with PoE++ self-powered operation, 46W PoE availability, ±16kV ESD protection, extreme -40°C to 65°C temperature tolerance, and full UniFi Layer 2 management in the most compact and weatherproof switch in the UniFi lineup.
