Ubiquiti UniFi Switch Flex 2.5G USW-Flex-2.5G-8 8-Port
The Ubiquiti UniFi Switch Flex 2.5G is a compact 8-port managed switch designed for small offices, home labs, and distributed network deployments where space and flexibility matter. It supports 2.5 GbE speeds across eight ports with a 10 GbE uplink, and runs on either USB-C or PoE+ power, eliminating the need for a separate power supply in many installations.
Why this product
8 × 2.5 GbE ports with 10 GbE uplink
Eight ports handle 2.5 Gbps devices at full speed, while the combination 10 GbE uplink accepts both RJ45 and SFP+ connections for flexible backbone design.
USB-C or PoE+ power
Connect via a standard USB-C adapter (5V, 3A) or draw power directly from a PoE+ source, allowing installation in tight spaces without additional infrastructure.
Wall, DIN, and magnetic mounting
Wall kit included; DIN rail support sold separately. Magnetic base and compact 212 × 76 × 33.5 mm form factor fit desktops, shelves, and equipment racks.
Layer 2 managed switching
VLAN support (256), port isolation, storm control, and port mirroring enable traffic segmentation and troubleshooting in small networks.
Runs UniFi Network OS
Integrates with Ubiquiti's UniFi ecosystem for centralized management alongside other UniFi devices (version 9.0.114 and later required).

- Any device with a 2.5 GbE, 1 GbE, or legacy 100 Mbps/10 Mbps Ethernet port connects directly to the eight RJ45 ports.
- The 10 GbE uplink accepts standard 10 GbE-capable switches, routers, and network interface cards via RJ45 or SFP+ optical transceivers.
- Powers from any 5V/3A USB-C charger or from PoE+ (44–57V DC) injectors and midspan devices.
- Requires UniFi Network software version 9.0.114 or later for management; older installations need an upgrade to use this switch.
- Does not support traditional wall power; USB-C or PoE+ are the only options.
Best for
- Small offices and home labs needing compact, flexible switching without dedicated AC outlets.
- Networks mixing legacy 100 Mbps devices with modern 2.5 GbE endpoints, all on one switch.
- Distributed deployments where PoE+ power sources already exist (cameras, APs, outdoor nodes).
- UniFi ecosystem users who want a managed switch that integrates with UniFi Network for centralized monitoring.
Trade-offs
- High-density enterprise environments; 8 ports and 30 Gbps non-blocking throughput are unsuitable for large data centers.
- Deployments requiring 10 GbE on all ports; only one 10 GbE uplink is available.
- Networks operating without UniFi infrastructure; this is a managed switch requiring UniFi Network for full features.
- Environments where AC power is unavailable and PoE+ uplinks cannot be provisioned; USB-C or PoE+ are mandatory.
Flexible, 8-port 2.5 GbE switch with a 10 GbE RJ45/SFP+ combination uplink port that can be powered with a USB-C or PoE+ adapter.
