Some chassis do not have all four cables. Be sure to match the name on the connectors to the corresponding pins.
PWRSW
Attach the power button cable from the case to these two pins. Pressing the power button on the front panel turns the system on and off rather than using the power supply button.
HD_LED
Attach the hard disk drive indicator LED cable to these two pins. The HDD indicator LED indicates the activity status of the hard disks.
RESET
Attach the Reset switch cable from the front panel of the case to these two pins. The system restarts when the RESET switch is pressed.
