Your Upgrade to 10-Gigabit: Compact, Quiet & Powerful
The UniFi Switch Flex XG is the answer to the growing demand for more bandwidth in the home office, small agencies, or ambitious home lab. While traditional Ethernet Switches reach their limits at 1 Gbit/s, this compact 10GbE Switch opens the door to a new performance class. Edit huge video files directly from Network-attached storage (NAS), create lightning-fast backups, or run multiple virtual machines without your Network becoming a bottleneck. Thanks to its desktop format, it fits discreetly on any desk.
Seamless Integration into your UniFi Network
As a full-fledged member of the Ubiquiti UniFi family, the USW-Flex-XG is centrally adopted and managed via the UniFi Network Application. This means for you: no more cumbersome logging into individual device web interfaces. Configure VLANs, set up Port Aggregation (LACP), or monitor traffic – all conveniently from a central dashboard. This manageable Layer-2 Network Switch offers you all the professional features you need for a stable and secure Network.
Thoughtful Design with Flexible Power Supply
Ubiquiti has thought of everything with the USW-Flex-XG. The fanless design guarantees absolutely silent operation, making it perfect for use directly at the workstation. The dual Power Supply option is also unique: Use an existing PoE+ Port of your core Switch for a clean installation with only one cable (power & 1G data) or opt for the included, powerful USB-C power adapter to use one of the 10-Gigabit Ports as an uplink and utilize full performance.
Strengths & Notes at a Glance
- Pro: Offers four 10GBASE-T ports in a very compact, desk-friendly form factor.
- Pro: The fanless design ensures absolutely silent operation, ideal for offices and studies.
- Pro: Flexible Power Supply via 802.3at PoE+ or the included USB-C power adapter.
- Pro: Seamless integration and central management via the UniFi Network Application.
- Note: The PoE uplink port is limited to 1 Gbit/s. For a true 10G uplink, power supply via USB-C is necessary.
- Note: The Switch has no PoE output (PoE Passthrough) and cannot power other devices.

Frequently Asked Questions (FAQ)
Can I use one of the 10G ports as an uplink to the rest of the Network?
Yes, absolutely. It is even recommended to use one of the four 10G ports as an uplink when operating the Ethernet Switch with the included USB-C power supply. This ensures that the full 10 Gbps bandwidth is available for communication with the core Network.
Can the USW-Flex-XG power other devices like WiFi Access Points via PoE?
No. The Ethernet Switch does not have a PoE output (PoE Out). The single 1GbE PoE port is exclusively an input (PoE-In) to power the Ethernet Switch itself, utilizing PoE Injectors / Power Supplies.
Do I absolutely need a UniFi Controller to use the Ethernet Switch?
For full functionality, configuration (e.g., VLANs), and monitoring, integration into a running UniFi Network Application is required. Without a controller, the UniFi Switch only operates with a basic configuration and cannot be managed effectively within your Network.
Is the Ethernet Switch fanless and suitable for a quiet environment?
Yes, the USW-Flex-XG is passively cooled and has no fans. It operates completely silently, making it ideal for use on a desk, in offices, or other noise-sensitive environments within your Network.
Do the 10G ports also support slower speeds like 2.5G and 5G?
Yes, the four 10GbE ports are Multi-Gigabit capable and automatically support speeds of 100 Mbps, 1 Gbps, 2.5 Gbps, 5 Gbps, and 10 Gbps, enhancing the versatility of this Ethernet Switch for your Network.
What is included with the Ubiquiti UniFi Switch Flex XG?
The standard retail package includes the USW-Flex-XG UniFi Switch itself, an external 5V/5A USB-C power supply, a wall Mounting Systems kit including a template, and a quick start guide, perfect for setting up your Ubiquiti Networks solution.
