The Ubiquiti USW-Flex- 2.5G -8 is a compact, high-performance Layer 2 switch that provides multi-gigabit connectivity with eight 2.5 GbE RJ45 ports plus a 10 Gb SFP+ uplink (or 10G RJ45 combo). It's well suited for bandwidth-intensive deployments such as Wi-Fi 6/6E access points, security cameras, and IoT devices. With a non-blocking throughput of 30 Gbps, a switching capacity of 60 Gbps, and a forwarding rate of 45 Mpps, the USW-Flex- 2.5G delivers efficient packet handling and stable network performance. It also supports advanced Layer 2 features-STP/RSTP, storm control, multicast/broadcast rate limiting, port isolation, and jumbo frames-making it a dependable option for modern network environments.

The Ubiquiti Flex 2.5G (USW-Flex-2.5G-8) is a managed Layer 2 desktop switch with eight 2.5 GbE ports and a 10 GbE RJ45/SFP+ combo uplink, suited to UniFi-managed home labs and small offices connecting multi-gigabit devices.
Recommended For
- Home-office users or small workgroups connecting several 2.5GbE computers, a NAS, and other wired devices in one area; the 10GbE uplink provides bandwidth for simultaneous traffic between the switch and the rest of the network.
- UniFi users who want to add multi-gig wired ports to a home or small-office network and manage features such as VLANs, port settings, and traffic through the UniFi system.
- Users placing a switch at a desk or in another spot without a convenient power outlet, who can power it from a PoE+ source over its uplink; USB-C power is also an option when PoE is unavailable.
- Small networks upgrading several wired devices from 1GbE to 2.5GbE, while keeping a faster 10GbE link between this switch and a compatible core switch or router.
Real-World Use Scenarios
- In a home office or small workgroup, connect several 2.5GbE computers and peripherals at one desk; the switch adds wired ports and can reduce local network bottlenecks when multiple devices are active.
- For a NAS and multi-gig PCs in the same room, use the switch to connect them locally and link it to a faster core switch; file transfers can use the faster device links, though each connected device remains limited by its own port speed.
- In a UniFi home or small-office network, use the managed switch to group wired devices with VLANs and monitor or control individual ports; this suits setups that need more organization than a basic unmanaged switch.
- At a network edge where power outlets are inconvenient, place the switch near wired devices and power the switch itself through PoE+ from upstream or with its USB-C adapter; this simplifies placement, but the non-PoE model does not provide PoE power to connected access points or cameras.
- For a wired access point with a 2.5GbE connection, use the switch to carry network traffic to the AP; arrange separate PoE power or a power adapter for the AP, since this switch’s PoE port is an input for powering the switch, not an output.
