Our take on the Ubiquiti USW-FLEX-2.5G-5 Compact, 5-Port 2.5G Switch that can be Powered with PoE or a USB-C Adapter

The Ubiquiti USW-Flex-2.5G-5 is a compact 5-port switch with four 2.5GbE RJ45 ports and one 10G SFP+ uplink, managed through UniFi. It is fanless and can be powered by PoE or a USB-C adapter, so it fits on a desk or in a small wiring closet without a power outlet nearby. It suits home labs and small offices that want multi-gigabit links to a NAS, access point or desktop without buying a full rack switch. Against cheaper unmanaged 2.5G switches it costs more and needs a UniFi controller to unlock its features, but it adds VLANs, link aggregation and a 10G uplink that those models lack.

What reviewers say

Owners of UniFi setups generally rate the switch well for its silent fanless design, 2.5GbE ports and 10G uplink in a small box. Complaints center on the need for a controller and the limited port count.

What people mention
  • NoisePraisedOwners note it runs silently because it has no fan.
  • SetupMixedAdoption is quick in UniFi, but a controller is needed to manage it.
  • PortsMixedThe 2.5G ports and 10G uplink are welcome, but four copper ports fill up fast.
  • PowerMixedPoE or USB-C power is convenient, though PoE input limits the power available to downstream devices.
  • BuildPraisedOwners describe the compact metal housing as solid for its size.

Questions and answers

Do I need a UniFi controller to use it?
It works as a basic switch without one, but VLANs, link aggregation and other managed features require a UniFi controller such as a Cloud Key or a self-hosted instance.
How is it powered?
It can take power over PoE from an upstream switch or injector, or from a USB-C adapter. PoE input limits how much power it can pass to downstream devices.
What is the SFP+ port for?
The 10G SFP+ uplink connects to a backbone switch, server or router with a compatible module or DAC cable, leaving the four 2.5G ports free for devices.
Is it rack-mountable?
No. It is a compact desktop unit with no rack ears, though it can sit on a shelf or be mounted with third-party brackets.
Does it support link aggregation?
Yes. Through UniFi it supports link aggregation, which lets you combine ports for more bandwidth to a NAS or server.
