Small, strong, smart: The UniFi Switch Flex Mini
The USW-Flex-Mini is the answer to one of the most common Network challenges: How do I expand my Network at endpoints without sacrificing management functions and a clean look? With dimensions barely larger than a credit card, you can discreetly hide this UniFi Switch anywhere. Its true strength lies in its flexibility: operate it easily via an existing PoE cable (operate unifi flex mini switch via poe) or use the included USB-C power adapter. This way, you can quickly create new Gigabit connections for your PC, printer, smart TV, or console.
Full Control with the UniFi Controller
Forget unmanaged switches that give you no insight into your Network. The USW-Flex-Mini is a full member of the UniFi family. After simple adoption into the UniFi Network Controller, you can configure each port individually. Assign specific VLANs to securely segment your home or office Network – for example, separate your work devices from guest WiFi or your IoT devices from the rest of the Network. Features like Port Mirroring or Storm Control provide you with tools typically found only in more expensive Enterprise Ethernet Switch models.
Perfect for Home Office and Media Corners
Thanks to its fanless design, the USW-Flex-Mini is absolutely silent, making it the ideal silent network switch for home office unifi. Its extremely low power consumption of under 2.5 watts not only protects the environment but also your electricity bill. It is the perfect, cost-effective solution for implementing a professional and manageable Network extension at any desk or in any media corner, without compromising on performance or control.

Frequently Asked Questions (FAQ)
Can the Ubiquiti USW-Flex-Mini power other devices (PoE Out)?
No, the USW-Flex-Mini does not support PoE-Out. It can only be powered via its Port 1 using 802.3af/at PoE (PoE-In), but it cannot power connected devices itself. This UniFi Switch is designed for efficient Network expansion.
Do I need a UniFi Controller to use the switch?
Yes, a UniFi Network Controller (software, Cloud Key, UDM, etc.) is absolutely necessary for configuring and managing 'smart' functions such as VLANs. Without adoption in the controller, it only functions as a simple unmanaged Ethernet Switch.
How is the USW-Flex-Mini connected to a cloud-based UniFi Controller?
Since the UniFi Switch does not support SSH, the usual 'set-inform' command is not possible. Adoption into a cloud controller requires special methods such as using the 'Ubiquiti Device Discovery Tools' or configuring DHCP Option 43 in the Router to inform the switch of the controller's address for optimal Network management.
Does the USW-Flex-Mini support Spanning Tree Protocol (STP)?
No, the UniFi Switch does not actively support STP. It merely forwards STP packets (BPDU). This means it cannot actively prevent Network loops itself, which can lead to issues in setups with redundant connections, impacting overall Network stability.
Can I operate a device at Gigabit speed on each of the 5 ports?
Yes, the UniFi Switch has a 'non-blocking throughput' of 5 Gbps. This means it can process data traffic on all five ports simultaneously at full Gigabit speed (1 Gbps per port) without bottlenecks, ensuring efficient Network performance.
Is the USB-C power adapter always included?
According to official Ubiquiti documentation, the 5V, 1A USB-C power adapter is only included in the single-pack of the USW-Flex-Mini. It may not be included in multi-packs for your Network setup.
