Three-pack managed PoE switch

The Ubiquiti Networks USW-Flex-3 (46W) is a three-pack of desktop Layer 2 managed switches. Each unit provides five GbE RJ45 ports with a total non-blocking throughput of 5 Gbps and a switching capacity of 10 Gbps. Four ports deliver PoE+ power and the switch itself can be powered via PoE++ or a separate 50V/60W adapter.

Indoor and outdoor deployments

The fanless design operates at 46W PoE output from -40 to 55 °C and at 25W output up to 65 °C, suiting indoor and outdoor installations. Humidity tolerance of 5 to 95 % non-condensing supports harsh environments. Buyers needing 10 GbE uplinks, Layer 3 routing or SFP ports should consider other models.

Compact PoE-powered node

Each switch measures 122.5 x 107.1 x 28 mm and weighs 230 g, fitting tight enclosures or pole mounts. PoE++ input eliminates a local power outlet, freeing AC sockets for other gear. The 50V/60W adapter is sold separately, so budget for it if no upstream PoE++ switch exists. Port isolation, mirroring, rate limiting and jumbo frames complete the Layer 2 feature set.
