This connector accommodates several system front panel functions.

when you turn on the system power, and blinks when the system is in sleep
mode.
• System Warning Speaker Lead (Orange 4-pin SPEAKER)
This 4-pin connector connects to the case-mounted speaker and allows you to
hear system beeps and warnings.
• Reset Switch Lead (Blue 2-pin RESET)
This 2-pin connector connects to the case-mounted reset switch for rebooting
the system without turning off the system power.
• ATX Power Switch / Soft-Off Switch Lead (Light Green 2-pin PWRSW )
This connector connects a switch that controls the system power. Pressing
the power switch turns the system between ON and SLEEP, or ON and SOFT
OFF, depending on the BIOS or OS settings. Pressing the power switch while
in the ON mode for more than 4 seconds turns the system OFF.
• Hard disk activity LED (Red 2-pin IDE_LED)
This connector supplies power to the hard disk activity LED. Any read or write
activity of an IDE device cause this LED to light up.
