UniFi Switch Flex 2.5G 5 (USW-Flex-2.5G-5): Managed 5-Port 2.5GbE Layer 2 Switch with PoE or USB-C Power

The Ubiquiti UniFi Switch Flex 2.5G 5 (USW-Flex-2.5G-5) is a compact, fully managed Layer 2 switch featuring five 2.5 Gigabit Ethernet ports, designed to expand high-performance home or business networks. With Multi-Gigabit connectivity, PoE or USB-C power options, and silent fanless operation, it’s the perfect choice for connecting modern devices that demand extra bandwidth — such as WiFi 6/7 access points, NAS units, or high-speed workstations.

Compact Multi-Gigabit Connectivity for Modern Networks

The USW-Flex-2.5G-5 brings 2.5GbE performance to UniFi’s most compact desktop form factor. Each of its five RJ45 ports supports speeds up to 2.5 Gbps, providing a simple and affordable way to upgrade your local wired network beyond traditional Gigabit speeds — without sacrificing efficiency or simplicity.

It can be powered through PoE In (802.3af/at) or via USB-C (5V DC), giving users maximum flexibility for deployment. The included AC adapter allows for quick setup right out of the box.

Managed through the UniFi Network platform, the switch offers essential Layer 2 features like VLANs, port mirroring, and per-port configuration — all accessible through UniFi’s intuitive web interface or mobile app.

Note: The USW-Flex-2.5G-5 does not provide PoE output to other devices.
