III.INSTALLATION

7.Message LED Lead (MSG.LED)

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).

8.SMI Suspend Switch Lead (SMI)

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)

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)

This 2-pin 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)

This 3-pin 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/System Power LED (KEYLOCK)

This 2-pin connector connects to the case-mounted keyboard lock switch to al- low keyboard locking.
