The Ultimate Guide to Installing and Configuring the Ubiquiti UniFi Switch Aggregation (USW-Aggregation)

The Ubiquiti UniFi Switch Aggregation (USW-Aggregation) is a powerful, high-capacity switch, perfect for streamlining and enhancing network performance. This guide will walk you through the steps of installing and configuring the USW-Aggregation for optimal performance.

What You Need

  • Ubiquiti UniFi Switch Aggregation (USW-Aggregation)
  • Ethernet cables
  • UniFi Controller software
  • Network diagram (optional but recommended for complex setups)

Step 1: Unboxing and Physical Setup

  • Unboxing: Carefully unbox your USW-Aggregation and check for all the essential components.
  • Placement: Choose a well-ventilated, accessible location for the switch.
  • Connections: Connect the power cable and plug it into a suitable power outlet. Then, connect your devices using Ethernet cables.

Step 2: Basic Configuration

  • Accessing the UniFi Controller: Open the UniFi Controller software on your computer. If you haven’t installed it yet, download it from Ubiquiti’s official website and follow the installation instructions.
  • Adopting the Switch: The USW-Aggregation should appear in the UniFi Controller. Click on it and select “Adopt” to integrate it into your network.
  • Basic Settings: Assign a name to your switch, set up the time zone, and update the firmware to the latest version for security and performance enhancements.

Step 3: Advanced Configuration

  • Network Segmentation: If needed, create VLANs for network segmentation, improving security and traffic management.
  • Port Configuration: Configure each port according to its purpose – for instance, setting up trunk ports for inter-switch connections or access ports for end devices.
  • Link Aggregation: For devices that support it, configure link aggregation to increase bandwidth and provide redundancy.

Step 4: Monitoring and Maintenance

  • Monitor Network Performance: Use the UniFi Controller to monitor network traffic, check the status of connected devices, and ensure everything is functioning correctly.
  • Regular Updates: Keep your switch’s firmware updated to protect against vulnerabilities and improve performance.
  • Backup Configuration: Regularly back up your configuration settings to prevent data loss in case of a failure.

Troubleshooting Common Issues

  • Connectivity Problems: If devices are not connecting, check the cable connections, port configurations, and ensure the switch is adopted in the UniFi Controller.
  • Firmware Issues: If you encounter issues after a firmware update, try resetting the switch to its factory settings and reconfiguring it.


The Ubiquiti UniFi Switch Aggregation is a versatile and powerful tool for enhancing your network’s performance. By following these steps, you can ensure a smooth installation and configuration process, leading to a more efficient and secure network.

Remember, every network is unique, so tailor the configuration to meet your specific requirements and always keep your system updated and monitored.
