• System Status LED Lead (2-pin MLED)
This 2-pin connector is for the system message LED that indicates receipt of
messages from a fax/modem. The normal status for this LED is ON, when there
is no incoming data signal. The LED blinks when data is received. The system
message LED feature requires an ACPI OS and driver support.
• ATX Power Switch / Soft-Off Switch Lead (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.
• Reset Switch Lead (2-pin RESET)
This 2-pin connector connects to the case-mounted reset switch for rebooting
the system without turning off the system power.
• System Power LED Lead (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 (4-pin SPEAKER)
This 4-pin connector connects to the case-mounted speaker and allows you to
hear system beeps and warnings.
