12. System panel connector (20-pin PANEL1)
This connector accommodates several system front panel functions.
•
System Power LED Lead (Green 3-pin PLED)
This 3-pin connector connects to the system power LED. The LED lights up
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 (Yellow 2-pin PWR )
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.
•
System Management Interrupt Lead (2-pin SMI)
This 2-pin connector allows you to manually place the system into a suspend
mode, or “green” mode, where system activity is instantly decreased to save
power and to expand the life of certain system components. Attach the
case-mounted suspend switch to this 2-pin connector.
•
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.
The System Panel connector is color-coded for easy and foolproof connection.
Take note of the specific connector colors as described.
