Step 6
Connect Front-Panel Switches/LEDs/USBs
You can find there are several different cables already existing in the system
case and originating from the computer's front-panel devices (Power On/Off
Switch, Reset Switch, Green LED/Power LED, HDD LED, or USB devices etc.)
These cables serve to connect the front-panel switches, LEDs, and USB
connectors to the mainboard's front-panel connectors group (JP8 and JP2/
JP3), as shown below.
1. ATX Soft Power On/Off (PWON)
2. Green LED and Power LED (GLED/PWR LED)
3. Hardware Reset Switch Button (RST)
4. HDD LED (HLED)
5. Extended USB Headers (JP2/JP3)
