1. Modification scope: The spacing between the motherboard and the corresponding socket is 2.54 mm, and the front panel switch plug uses individual terminals, not a single integrated connector. 2. This extension switch supports full power-on and reset functions. The POWER LED and HDD LED indicators are visible on the external switch. 3. The frequently used power button is positioned at the bottom of the unit, while the less frequently used reset button is located at the top. The power indicator features a colorful, circulating light effect beneath the keycap. The hard drive activity indicator is visible through a small aperture on the unit. Installation instructions: 1. First installation method: Connect the switch’s terminal wires directly to the corresponding pins on the motherboard’s F_PANEL header. Use only the external switch. 2. To retain the front-panel reset function while using this external switch, use the included adapter to split the connections—each function is duplicated across two separate wires, enabling simultaneous operation of both the original front-panel controls and the external switch. 3. The switch can be mounted in any convenient location using the included double-sided adhesive pad.
