12. System panel connector (20-pin PANEL)
This connector accommodates several system front panel functions.
• System Power LED Lead (Green 3-1 pin PLED)
This 3-1 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 SPKR)
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 PWRBTN )
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 (Light Blue 2-pin SMI)
This 2-pin connector allows you to manually place the system into a
suspended 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.
