III. HARDWARE SETUP 9. System Message LED Lead (2-pin 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. This function requires ACPI OS support. 10. System Management Interrupt Switch Lead (2-pin 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 expand the life of certain components when the system is not in use. This 2-pin connector (see the figure below) connects to the case-mounted suspend switch. If you do not have a switch for the connector, you may use the "Turbo Switch" since it does not have a function. SMI is activated when it detects a short to open moment and therefore leaving it shorted will not cause any problems. May require one or two pushes depending on the position of the switch. Wake-up can be controlled by settings in the BIOS but the keyboard will always allow wakeup (the SMI lead cannot wake-up the system). If you want to use this connector, "Suspend Switch" in Power Management Setup of BIOS SETUP section should be on the default setting of Enable. 11. ATX Power & Soft-Off Switch Lead (2-pin PWR.SW) The system power can be controlled by a momentary switch connected to this lead. Pushing the button once will switch the system between ON and SLEEP. Pushing 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. 12. Reset Switch Lead (2-pin RESET) This 2-pin connector connects to the case-mounted reset switch for rebooting your computer without having to turn off your power switch This is a preferred method of rebooting in order to prolong the life of the system's power supply. 13. System Power LED Lead (3-1 pin PWR.LED) This 3-pin connector connects the system power LED, which lights when the system is powered on and flashes when it is in sleep mode. 14. Keyboard Lock Switch Lead (2-pin KEYLOCK) This 2-pin connector connects to the case-mounted key switch to allow keyboard locking. 15.
