UniFi Switch Flex 2.5G 8 (USW-Flex-2.5G-8): Compact Layer 2 Managed Switch with 8× 2.5GbE + 10G RJ45 + 10G SFP+

The Ubiquiti UniFi Switch Flex 2.5G 8 (USW-Flex-2.5G-8) delivers next-generation multi-gigabit performance in a compact, silent, and versatile form factor. Featuring eight 2.5GbE ports, one 10GbE RJ45 port, and one 10G SFP+ uplink, this switch is ideal for home labs, creative studios, and small businesses that demand high-speed wired connectivity without PoE output.

⚡ Multi-Gigabit Speed Meets 10G Flexibility

The USW-Flex-2.5G-8 provides Layer 2 managed switching with true 2.5GbE performance across all ports, ensuring ultra-fast connections for devices such as PCs, NAS units, and Wi-Fi 6/7 access points (with their own power).
The dual 10G uplink options — one 10GbE RJ45 and one 10G SFP+ — offer maximum flexibility for linking to your network core, servers, or high-performance storage systems.

🔌 Versatile Power Options (PoE+ or USB-C)

Power the switch your way:

• PoE+ (802.3at) input — Simplify installation with a single Ethernet cable, ideal for clean setups.

• USB-C (5V/5A) input — Perfect for desktop or mobile use, offering greater flexibility and convenience.

Both methods provide stable and efficient power for demanding environments.

🧩 Compact, Flexible Design for Any Environment

The Flex form factor makes the switch easy to place on a desk, wall, DIN rail, or metal surface (mounting accessories optional).
Its fanless design ensures silent operation, making it ideal for offices, recording studios, or technical rooms where noise is undesirable.

🧠 Comprehensive UniFi Network Management

Managed through the UniFi Network Controller (v9.0.114 or later), the USW-Flex-2.5G-8 supports a complete range of Layer 2 features:

• VLANs (802.1Q)

• STP/RSTP

• LACP (Link Aggregation)
