UBIQUITI NETWORKS Unifi Switch Usw-flex-mini-2.5g

The USW-Flex is a compact, weatherproof PoE-powered network device designed for indoor and outdoor deployments. It supports a maximum PoE output budget of 46W when supplied by a 60W 802.3bt PoE++ source and provides four auto-sensing 802.3af PoE ports to power connected devices. The unit can be mounted horizontally or vertically, and its rugged housing is built to withstand environments with extreme temperature variations. The USW-Flex integrates with UniFi Controller for centralized management across multiple sites.

Advantages

The USW-Flex offers flexible Power over Ethernet capability, supporting up to 46W output when paired with a 60W 802.3bt PoE++ power source and delivering 802.3af PoE on four ports. Its versatile mounting options—desktop, magnetic wall-mount or pole-mount—allow installation in diverse locations. Weatherproof construction enables reliable operation both indoors and outdoors. The device is compatible with a range of UniFi devices that use 802.3af PoE and can be managed centrally through the UniFi Controller.

Key specifications

• Maximum PoE output budget: 46W (when powered by 60W 802.3bt PoE++)
• PoE output ports: Four auto-sensing 802.3af ports
• Power input requirement: 60W 802.3bt PoE++ to enable full budget
• Mounting options: Horizontal or vertical (desktop, magnetic wall-mount, pole-mount)
• Environmental design: Weatherproof housing for indoor and outdoor use
• Management: Compatible with UniFi Controller for centralized, multi-site management

How to use

Install the USW-Flex in the desired orientation (horizontal or vertical) using the appropriate mounting method for your location. Connect a 60W 802.3bt PoE++ source to enable the full 46W PoE output budget, then connect up to four 802.3af-powered devices to the auto-sensing PoE ports. Place the unit in a location where its weatherproof enclosure and temperature tolerance meet environmental needs. Add the device to your UniFi Controller instance to configure network settings and manage multiple sites from a centralized interface.

Recommendations

To achieve maximum power delivery, power the USW-Flex with a 60W 802.3bt PoE++ source such as the USW-Industrial switch. Use compatible 802.3af devices like UniFi Video Camera G3 Flex, UniFi Video Camera G4 Pro, or UniFi AC Mesh AP. For streamlined management, add the unit to a UniFi Controller instance running in the cloud or on-premises to maintain separated site configurations and centralized monitoring.
