2.5 GbE PoE++ for High-Performance Devices

Eight 2.5 GbE PoE+ ports deliver up to 15.4 W per port, powering IP cameras, wireless access points, and VoIP phones without separate adapters. This eliminates clutter and reduces installation time, making it ideal for expanding smart office or surveillance setups.

10 GbE Uplink for Future-Proof Backhaul

The dedicated 10 GbE RJ45/SFP+ combo port provides high-capacity uplink to backbone switches or servers. Whether you choose copper or fibre via SFP+, you gain headroom for growing bandwidth demands without replacing the switch.

Advanced Network Management

As a Layer 2 managed switch, the UniFi Flex supports VLANs, port mirroring, rate limiting, and broadcast storm control. These features give administrators granular control over traffic shaping and security, ensuring stable performance in mixed-use environments.

Flexible Mounting and Power Options

Mount the switch on a desktop, wall, or DIN rail to suit your rack or workspace. Power can come from PoE++ on the uplink port, a 54 V DC adapter (sold separately), or AC/DC sources, offering deployment flexibility in varied installations.
