Setup and Installation
Before beginning installation, ensure your computer is completely powered off and unplugged from the wall outlet. It is recommended to consult your motherboard's manual for precise front panel header pinouts.
Step 1: Accessing Motherboard Headers
Open your computer case to gain access to the motherboard. Locate the front panel header pins, typically found at the bottom right corner of the motherboard. These headers are usually labeled for Power SW, Reset SW, Power LED+, Power LED-, HDD LED, USB, and Audio.

The image also illustrates how to plug the USB and Audio jacks directly into their respective interfaces on the motherboard.
Step 2: Connecting the Cables
Carefully connect the corresponding cables from the XMSJSIY switch to your motherboard's front panel headers. The cables are labeled as follows:
- POWER SW: Connects to the Power Switch pins.
- RESET SW: Connects to the Reset Switch pins.
- POWER LED+ / POWER LED-: Connects to the Power LED pins. Ensure correct polarity for the LED to light up.
- USB: Connects to an available USB header on your motherboard.
- AUDIO: Connects to the Audio header (usually labeled F_AUDIO or similar).
Note: The positions of the sockets are different on various motherboards. Always refer to your motherboard's manual for accurate pinout diagrams. When connecting the LED cables, ensure the colored line (positive) aligns with the '+' pin on the motherboard header.
Step 3: Positioning the Switch Unit
The switch unit features adhesive sticky pads on the bottom for secure placement on your desk or any flat surface. Position the unit in a convenient location that allows easy access to the buttons and ports.

- Reset Button: Press the smaller button (often labeled 'Reset SW' or similar) to restart your computer.
- USB Ports: Use the two integrated USB ports for connecting peripherals such as keyboards, mice, USB drives, or charging devices.
- Audio Ports: Plug in your headphones or microphone into the respective audio jacks for sound input and output.
