Ubiquiti UniFi Flex 2.5G 8-Port Switch - Compact Multi-Gig Layer 2 Switch with 10G Combo Uplink
The Ubiquiti UniFi Flex 2.5G 8-Port (USW-FLEX-2.5G-8) is a compact Layer 2 managed switch with eight 2.5 GbE RJ45 ports and one 10G RJ45/SFP+ combo uplink. Every port runs at 2.5 Gbps over standard Cat5e cabling, so NAS traffic, workstation backhaul, and WiFi 6E/7 AP uplinks all exceed gigabit without requiring 10G infrastructure at every endpoint.
The Flex 2.5G 8-Port is the non-PoE member of the UniFi Flex 2.5G switch family. It shares the same multi-gig port speed and 10G combo uplink as the Flex 2.5G PoE variant, but drops PoE output in exchange for a fanless enclosure, 14W power draw, and a form factor small enough for a desktop, wall mount, or DIN rail. Power the switch itself from a USB-C adapter or a PoE switch port upstream.
Where the Flex 2.5G 8-Port Fits
- Home labs and media rooms connecting a NAS, gaming PC, streaming box, and WiFi 7 AP at 2.5 Gbps each, with a 10G uplink back to a core switch or router that keeps aggregate throughput from bottlenecking at 1 Gbps
- Small offices and workgroups where 4-8 workstations need more than gigabit to shared storage or a local server, without the cost, heat, or rack space of a larger managed switch
- IDF closets and industrial panels using the DIN rail mount to add a managed multi-gig switch inside a structured wiring enclosure, electrical panel, or AV rack where desktop form factors do not fit
What the Flex 2.5G 8-Port Delivers
- 8x 2.5 GbE ports: Every RJ45 port runs at 2.5 Gbps over standard Cat5e cabling. No need for Cat6a or special patch panels. Devices that support 2.5G negotiate up; everything else falls back to 1G or 100M automatically.
- 1x 10G RJ45/SFP+ combo uplink: A single uplink port that accepts either a 10G RJ45 copper connection or a 10G SFP+ module. Use RJ45 for a short run to a NAS or SFP+ for a fiber run to a core switch in another room.
- Layer 2 managed: 802.1Q VLANs, IGMP snooping, port mirroring, spanning tree, and storm control all managed through UniFi Network. Segment traffic, monitor ports, and maintain loop protection from the same dashboard as every other UniFi device in the deployment.
- Fanless and compact: Polycarbonate enclosure (8.4 x 3 x 1.3 in., 13.93 oz) with no moving parts. 14W total power draw. Silent operation for desktops, AV racks, and anywhere noise matters.
- USB-C or PoE powered: Power the switch from the included USB-C adapter or from a PoE switch port upstream. No separate wall outlet required when powered via PoE.
