Ubiquiti UniFi Flex 2.5G Managed Switch

The Ubiquiti USW-FLEX-2.5G-5 delivers enterprise-grade 2.5 Gigabit Ethernet connectivity in an ultra-compact form factor. This 5-port managed switch bridges the gap between standard gigabit and expensive 10G infrastructure, making it ideal for small offices, home networks, and edge deployments requiring higher bandwidth.

Flexible Power Options

Power the switch using either the included USB-C adapter (5V DC, 1A) or PoE input (44V-57V), providing installation flexibility without requiring nearby AC outlets. The switch consumes just 5W via AC/DC or 6.4W via PoE input, maintaining energy efficiency while delivering full 2.5GbE performance across all ports.

2.5 Gigabit Performance

All five RJ45 ports support 2.5 Gigabit Ethernet, delivering 10 Gbps switching capacity and 12.5 Gbps total non-blocking throughput. With a forwarding rate of 19 Mpps, this switch handles demanding applications including high-resolution video streaming, large file transfers, and multi-gigabit internet connections without bottlenecks.

Advanced Network Management

Managed through UniFi Network version 8.6.9 and later, the switch supports 256 VLANs with a MAC address table size of 4000. Network administrators gain access to STP/RSTP, egress rate limiting, flow control, storm control, multicast/broadcast rate limiting, port isolation, port mirroring, jumbo frames, and loop protection. These enterprise features enable sophisticated network segmentation and traffic management.

Compact Desktop Design

Measuring just 117.1 x 90 x 21.2 mm (4.6 x 3.5 x 0.8") and weighing 206 g (7.3 oz), the polycarbonate enclosure fits seamlessly into space-constrained environments. The desktop form factor eliminates the need for rack mounting while maintaining professional network capabilities.

CE, FCC, and IC certified for reliable operation in commercial and residential deployments.
