All four ports are RJ-45 jacks running at up to 10 Gbit/s, so no SFP+ modules or fibre are needed. Each port adapts to the device on the other end and also supports 2.5 and 5 Gbit/s as well as plain gigabit. A workstation with a 10G network card, a NAS with a 5G interface and an older gigabit device can share one switch, each running at its own top speed.
The switching capacity is 82 Gbit/s and the forwarding rate 61.012 million packets per second. In practice, all four 10G ports and the gigabit input port can run at full speed at the same time in both directions. When a workstation copies large video files to the NAS while another stream heads to the router, the switch does not have to queue the traffic.
One gigabit RJ-45 port is a PoE+ input to the IEEE 802.3at standard. If a PoE+ switch is nearby, the USW-Flex-XG can take its power over that same cable, with no separate power brick at the wall. That simplifies installation where the nearest outlet is far away, for example behind a shelf or near the ceiling. The included power supply accepts 90–264 V AC, and maximum consumption is 25 W.
The housing is slim and small at 135 × 185 × 32 mm and 1.2 kg, in white polycarbonate. According to the manufacturer it is meant for the desktop, and rack mounting is not supported. There are LED indicators and a reset button for restoring factory settings when needed. The operating range of −5 to 45 °C suits an office, a home or a media cabinet.
The USW-Flex-XG is a fully managed Layer 2 switch. It can be monitored and configured in the UniFi Network web application and mobile app, including remotely. If the network already has other UniFi devices, the switch shows up in the same management view and its status is visible alongside the rest of the network.
Video editors and photographers who move large files between a workstation and a NAS; home lab owners who want 10G for a few devices without a rack switch; small offices whose server corner sits on a desk; and UniFi users who need a 10G branch switch in a spot that only one PoE+ cable reaches.

The manufacturer lists PoE+ only as an input: the switch itself can be powered over PoE+. PoE output on the 10G ports is not mentioned.
No. All four 10G ports are standard RJ-45 jacks for network cable; this model has no SFP+ slots.
Yes, it is a managed Layer 2 switch, configured and monitored in the UniFi Network web or mobile app.
No, according to the manufacturer rack mounting is not supported. The compact 135 × 185 × 32 mm housing is designed for the desktop.
