Ubiquiti UniFi Switch Flex Mini 2.5G (USW-Flex-2.5G-5)
The Switch Flex Mini 2.5G is a compact 5-port 2.5 GbE switch from Ubiquiti. All five RJ45 ports run at up to 2.5 Gbps, and one of them doubles as a PoE input, so the switch can be powered over the network cable or from the included 5V, 1A USB-C adapter. It sits on a desk and is managed in the UniFi Network application, version 8.6.9 and later.
Quick Glance
Key Features
Five 2.5 GbE ports in a compact switch
All five RJ45 ports support 2.5G, 1G, 100M and 10M. Ubiquiti rates switching capacity at 25 Gbps, total non-blocking throughput at 12.5 Gbps and the forwarding rate at 19 Mpps, with a 4,000-entry MAC address table. The polycarbonate unit measures 117.1 x 90 x 21.2 mm and weighs 206 g.
Powered by PoE or the included USB-C adapter
One of the five ports is a 2.5 GbE PoE input, so the switch can take its power from an upstream PoE port (44V to 57V). Alternatively, use the included 5V, 1A USB-C adapter. Maximum power consumption is 5W on AC/DC input and 6.4W on PoE input. The switch has no PoE output.
Managed in UniFi Network
Managed from the UniFi Network application (8.6.9 and later), it supports up to 256 VLANs, STP and RSTP, storm control, multicast and broadcast rate limiting, egress rate limiting, flow control, port isolation, port mirroring, jumbo frames and loop protection.
Detailed Specifications
Specifications are from Ubiquiti's official tech specs and store listing for the Switch Flex Mini 2.5G (USW-Flex-2.5G-5). Ubiquiti states the EU version comes with an EU power plug only. Ubiquiti may update specifications without notice.
Need-to-Know
- The switch has five 2.5 GbE ports in total; one of them is the PoE input port used for power. Ubiquiti's spec lists no PoE output, so it cannot power other devices.
- Two ways to power it: from an upstream PoE port (44V—57V PoE) or from the included 5V, 1A USB-C adapter.
- Ubiquiti states that the EU version comes with an EU power plug only. Ubiquiti sells EU and UK versions; check the plug on the version supplied if you will use the USB-C adapter.
- Ubiquiti lists the form factor as compact desktop and gives no other mounting option for this model.
- Managing the switch needs the UniFi Network application, version 8.6.9 or later.
