The Ubiquiti Flex 2.5G PoE (USW-Flex-2.5G-8-PoE) is a versatile, compact, and fanless UniFi managed switch engineered to deliver multi-gigabit copper connectivity and advanced PoE power delivery. Featuring eight 2.5 GbE RJ45 ports supporting PoE++ output, it provides high-speed Ethernet connections suitable for modern deployments requiring reliable power and data transmission.

This switch includes a single 10 GbE RJ45/SFP+ combination uplink port capable of 10G/5G/2.5G/1G/100M speeds, which can serve as either a power input with PoE+++ or as a data uplink through the SFP+ port. It offers flexible power options including PoE+++ input or an optional AC power adapter (sold separately) with various PoE power budgets to fit deployment needs.

Designed for flexibility, the unit supports desktop, wall, DIN-rail (adapter sold separately), and magnetic mounting within a tough polycarbonate enclosure. Its silent, fanless design makes it ideal for noise-sensitive environments.

Performance highlights include a switching capacity of 60 Gbps, non-blocking throughput of 30 Gbps, and a forwarding rate of 45 Mpps, ensuring low latency and high data integrity for demanding network operations.

It supports essential Layer 2 networking features such as STP/RSTP, up to 256 VLANs, port isolation, port mirroring, jumbo frames, storm control, multicast/broadcast rate limiting, flow control, and proprietary loop protection to maintain network reliability and security.

The switch is easily manageable via the UniFi Network application, offering centralized control and monitoring capabilities with minimum software version requirements.

Key Usage Scenarios:

  • Small to medium enterprise networks requiring multi-gigabit speed

  • Deployments needing PoE++ power delivery for devices like access points, cameras, and VoIP phones

  • Network setups requiring flexible and silent device placement
