5-Port Layer 2 Gigabit Switch with PoE Support


Build and expand your network with the UniFi® Switch Flex, model USW-Flex. It is a configurable Layer 2 Gigabit switch with auto-sensing 802.3af PoE. Five RJ45 Gigabit Ethernet ports provide one PoE input and four PoE output links to your devices.

Switching Performance
The USW-Flex offers the forwarding capacity to simultaneously process traffic on all ports at line rate without any packet loss.

PoE Flexibility
The USW-Flex features five Gigabit RJ45 ports to deliver robust performance and intelligent switching for your network. Port 1 provides PoE input while ports 2-4 offer 802.3af PoE and provide up to 15W of power for your PoE devices. Products requiring 802.3af, such as G3 Flex cameras, are supported.

Indoor/Outdoor Design
The USW-Flex can be installed horizontally or vertically and offers versatile mounting options: desktop, wall, and pole. The weather-resistant USW-Flex can withstand extreme temperature variations. If the USW-Flex is installed at an exposed location outdoors, we recommend the UniFi Switch Flex Utility, model USW-Flex-Utility, which is designed for use with the USW-Flex.

Outdoor Enclosure Accessory
An outdoor weatherproof enclosure, the USW Flex Utility, is available as an optional accessory. It includes an Ethernet patch cable and a 60W PoE adapter, which provides a maximum PoE budget of 46W. Easily mounted on a pole, the USW Flex Utility provides clean cable management and a screw lock for security.
