Connect Front-Panel LEDs/Switch/USBs
You can find there are several different cables already existing in the system
case and originating from computer's front-panel devices (MSG LED, HDD
LED, PWR BTN, RST switch, or USB devices etc.). These cables serve to
connect the front-panel LEDs, switch, and USB connectors to mainboard's
front-panel connector groups (PANEL1 and USB3), as shown below.
1. ATX Soft Power On/Off (PWR)
2. Hardware Reset Switch Button (RST)
3. Green-LED (MSG LED)
4. HDD-LED (HD LED)
5. Extended USB Headers (USB 2&3)
