Three compact Layer 2 switches

This three-pack delivers three identical 5-port managed switches for small networks. Each unit fits on a desktop and draws power either from the single PoE input port or from the included 5V USB-C adapter. The fanless design runs silently in offices or home labs. Managed Layer 2 features give control over traffic without the complexity of Layer 3 routing.

Replaces unmanaged desktop switches

Moving up from a basic unmanaged switch adds port isolation, storm control, port mirroring and multicast rate limiting. The jump is worth it when you need to segment devices, prevent broadcast storms or mirror traffic for diagnostics. Builders who need Layer 3 routing, 10 GbE uplinks or SFP ports should look elsewhere. The 5 Gbps non-blocking throughput suits modest bandwidth needs.

Sustained traffic at wire speed

The 10 Gbps switching capacity and 7.44 Mpps forwarding rate handle continuous gigabit flows across all ports without head-of-line blocking. Operating temperature spans -5 to 45 °C, so the switch tolerates warm cabinets or outdoor enclosures. Humidity range of 10 to 90 % non-condensing supports damp environments. No moving parts means no fan wear during long-term deployment.

Questions about this item

What are the exact dimensions of each USW-Flex-Mini switch so I can check if it fits my cabinet?

Each switch measures 107 x 70 x 21 mm (4.2 x 2.8 x 0.8") and weighs 150 g (5.3 oz), making it compact enough for tight desktop or wall-mounted spaces.

How do I power the Flex Mini switches and which port do I use for PoE input?

Connect the PoE source to the dedicated GbE PoE input port on each switch; alternatively, use the included 5V, 1A USB-C adapter (provided with single units) for non-PoE deployments.

What ongoing maintenance do the Fanless Flex Mini switches require after installation?

With no moving parts and an operating range of -5 to 45° C (23 to 113° F) at 10 to 90% noncondensing humidity, the switches need only occasional dust removal and cable checks.
