The Ubiquiti UniFi Switch Flex 2.5G 8 PoE (Model: USW-Flex-2.5G-8-PoE) is an ultra-versatile, multi-gigabit Layer 2 edge switch engineered to deliver high-density power and bandwidth to modern enterprise endpoints. Designed for high-demand deployments—such as feeding Wi-Fi 6E and Wi-Fi 7 Access Points, PTZ security cameras, door access hubs, and creative workstation clusters—it eliminates local power and bandwidth bottlenecks by pairing 2.5 GbE client connectivity directly with powerful 802.3bt PoE++ output capabilities.
Built with exceptional versatility, the switch features eight 2.5 GbE RJ45 ports that support high-power PoE++ output up to 64W per port. For core aggregation, the USW-Flex-2.5G-8-PoE provides dual 10 GbE uplinks: one 10G SFP+ optical interface and one 10G RJ45 port. The 10G RJ45 port doubles as a PoE+++ power input, enabling the switch to operate without a local AC wall outlet while distributing up to 76W of PoE power to downstream devices. Alternatively, connecting an optional 210W external AC power adapter expands total PoE availability to a massive 196W. Its durable polycarbonate housing supports multiple installation methods—including desktop, wall, DIN rail, or magnetic mounting—and integrates directly into the UniFi Network software for centralized Layer 2 control.
