• Cable Management: Keep cables neatly organized to prevent strain on ports and accidental disconnections.

8. Troubleshooting

If you encounter issues with your KVM switch, please refer to the following common solutions:

• No Display/Video Output:
  • Ensure all HDMI cables are securely connected to both the KVM switch and the computers/monitor.
  • Verify that the correct input is selected on the KVM switch.
  • Try connecting the monitor directly to the computer to confirm the computer's video output is working.
  • Restart the KVM switch and all connected computers.
• Keyboard/Mouse Not Working:
  • Ensure the USB-B cables are securely connected from the computers to the KVM switch.
  • Verify that the keyboard and mouse are connected to the dedicated USB Keyboard/Mouse ports on the KVM switch.
  • Try connecting the keyboard/mouse directly to the computer to confirm they are functional.
  • Some specialized keyboards/mice (e.g., gaming, wireless with proprietary receivers) may require connection to the front USB 2.0 ports instead of the dedicated KVM ports.
• USB 2.0 Devices Not Detected:
  • Ensure the USB-B cables are connected from the computers to the KVM switch.
  • Verify the USB device is properly connected to the front USB 2.0 ports.
  • Check if the device requires external power.
• Hotkeys Not Working:
  • Ensure your keyboard is connected to the dedicated USB Keyboard port.
  • Try using the alternative hotkey (e.g., if Scroll Lock doesn't work, try Ctrl).
  • Some multimedia keyboards may interfere with hotkey functionality. Try a standard keyboard for testing.
