Attach peripherals — such as mouse, keyboard, external storage, and monitor — to the appropriate USB, VGA, and Ethernet ports. If required, secure the device with a Kensington cable lock. Follow the host operating system prompts to install any necessary drivers or allow the system to recognize connected devices.

Recommendations

For optimal performance, connect high-speed devices to the USB 3.2 Gen 1 Type-A ports and reserve the USB 2.0 ports for lower-bandwidth peripherals. Use the Ethernet port for tasks that require stable network throughput such as file transfers, video conferencing, or remote desktop sessions. When connecting older monitors or projectors, verify display settings on the host to ensure correct resolution via the VGA output.
