UniFi Switch Flex 2.5G 8 PoE (USW-FLEX-2.5G-8-POE): Compact Managed L2 Switch with 8× 2.5GbE PoE++ and Dual 10G Uplinks

The Ubiquiti UniFi Switch Flex 2.5G 8 PoE (USW-FLEX-2.5G-8-POE) combines multi-gigabit performance with powerful PoE++ delivery in a compact and flexible form factor. Featuring eight 2.5GbE RJ45 ports, all supporting PoE++ (802.3bt, up to 64W per port), and dual 10GbE uplinks (1× RJ45 + 1× SFP+), this switch is ideal for powering and connecting WiFi 6/7 Access Points, 4K/8K IP cameras, control panels, or high-end VoIP systems — all through a single device.

⚡ Multi-Gigabit Speed Meets High-Power PoE++

Deliver both bandwidth and power where it’s needed most.
All eight 2.5GbE ports support PoE++ up to 64W per port, enabling seamless deployment of power-hungry devices such as:

• WiFi 6/7 Access Points

• UniFi Protect PTZ cameras

• AV-over-IP and digital signage systems

• High-performance VoIP and automation devices

🔌 Dual 10G Uplinks (RJ45 + SFP+)

The USW-FLEX-2.5G-8-POE includes both a 10GbE RJ45 uplink (which can also act as PoE In) and a 10G SFP+ fiber uplink, offering maximum flexibility for core connectivity — whether via copper or fiber backhaul.

⚙️ Flexible Powering Options

Choose the best power method for your installation:

• PoE+++ Input (10GbE RJ45 port): up to 76W PoE budget

• Optional 210W AC Adapter: unlocks full 196W PoE power across all ports

• PoE+ or PoE++ Input: economical options for smaller setups (16–46W PoE budget)

This flexibility allows the switch to scale from desktop PoE distribution to professional-grade multi-device deployments.

🧩 Compact, Silent, and Ultra-Versatile Installation

With its fanless design and compact Flex chassis, the switch can be installed anywhere — on a desk, wall, DIN rail, or magnetic surface (mounting accessories optional).
Perfect for offices, technical rooms, studios, or smart homes.
