• 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.
• System Message 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 OFF, 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.
• 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.
