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-on 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.
Power LED Header
(Green)
: ACPI_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.
Speaker Header
(Purple)
: SPK1
A speaker cable on your case front panel can be attached to this header. When you reboot the
computer, this speaker will issue a short audible (beep). If there are problems during the Power
On Self-Test, the system will issue an irregular pattern of audible beeps through this speaker.
