III. INSTALLATION
7. Message LED Lead (MSG.LED, 2 pins)
This indicates whether a message has been received from a fax/modem. The
LED will remain lit when there is no signal and blink when there is data transfer
or messages waiting in the inbox. This function requires OS and driver support.
8. SMI Suspend Switch Lead (SMI, 2 pins)
This allows the user to manually place the system into a suspend mode or "Green"
mode where system activity will be instantly decreased to save electricity and ex-
pand the life of certain components when the system is not in use. This 2-pin con-
nector connects to the case-mounted suspend switch. If the switch is not available,
you can use the turbo switch. SMI is activated when it detects a short to open mo-
ment; leaving it shorted, therefore, will not cause any problems. This may require
one or two presses depending on the switch's position. Wake-up can be controlled
through the BIOS but the keyboard will always wake-up (the SMI lead cannot
wake up) the system. If you want to use this connector, the "Suspend Mode" under
Power Management Setup of the BIOS SOFTWARE must be set to Enable.
9. ATX Power Switch/Soft Power Switch Lead (PWR.SW, 2 pins)
The system power can be controlled by a momentary switch connected to this
lead. Pressing the button once will switch the system between ON and SLEEP.
Pressing the switch while in the ON mode for more than 4 seconds will turn the
system off. The system power LED shows the status of the system's power.
10. Reset Switch Lead (RESET, 2 pins)
This connector connects to the case-mounted reset switch to allow the restarting
of your computer without having to turn it off. This is a preferred method of
restarting to prolong the life of the system's power supply.
11. System Power LED (PWR.LED, 3 pins)
This connector connects the system power LED, which lights when the system
is powered on and blinks when it is in sleep mode.
12. Keyboard Lock Switch Lead (KEYLOCK, 2 pins)
This 2-pin connector connects to the case-mounted keyboard lock switch to al-
low keyboard locking.
13. Speaker Connector (SPEAKER, 4 pins)
This 4-pin connector connects to the case-mounted speaker.
