Hard Drive LED Header: HDLED
If your case front panel has a hard drive LED cable, attach it to this header. The LED will flicker when
there is hard disk drive activity.
Reset Switch Header: RESET
This header can be attached to a momentary SPST switch (reset button) cable on your case front panel.
The switch is normally left open. When the switch closed, it will cause the mainboard to reset and run the
POST (Power-On Self Test).
Power-on Switch Header: PWRBTN
This header can be attached to a power switch cable on your case front panel. You can turn your system
on or off by pressing the button attached to this power switch cable.
2-pin
Power LED Header: PWR LED
These mainboards provide a 2-pin power LED header. If there is a 2-pin power LED cord on your case
front panel, you can attach it to the 2-pin power LED header. Then the power LED will illuminate while the
system is powered on.
3-pin
Power LED Header: PWRLED
These mainboards also provide a 3-pin power LED header. If there is a 3-pin power LED cord on your
case front panel, you can attach it to this 3-pin header instead of attach to the 2-pin one on the SW/LED
header.
