Hard Drive LED Header
(Red)
: HD_LED
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
(Blue)
: RST_SW
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 Switch Header
(Orange)
: PWR_SW
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
(Green)
: PWR_LED
The mainboard provides 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
(Green)
: PWR_LED
The mainboard also provides 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.
