1 R 1 III. INST ALLATION Connectors III. INSTALLATION 14. 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 waiting in the inbox. This function requires ACPI OS and driver support. 15. System Management Interrupt Switch Lead (SMI) This allows the user to manually place the system into a suspend mode or "Green" mode where system activity is decreased to save electricity and expand the life of certain components when the system is not in use. This 2-pin connector connects to the case-mounted suspend switch. If you do not have a switch for the connector, you may use the "Turbo Switch". SMI is activated when it detects a short to open moment and therefore leaving it shorted will not cause any problems. This may require one or two presses depending on the position of the switch. Wake-up can be controlled by settings in the BIOS but the keyboard will always allow wake-up (the SMI lead cannot wake up the system). If you want to use this connector, set "Suspend Mode" under the Power Management Setup of the BIOS SOFTWARE section to the preferred time after which the system must go into suspend mode when you press the switch. 16. ATX Power Switch / Soft Power Switch (PWR.SW) The system power is controlled by a momentary switch connected to this lead. Pushing the button once will switch the system between ON and SLEEP or ON and SOFT OFF, depending on your BIOS or OS setting. 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. 17. Reset Switch Lead (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 to prolong the life of the system's power supply. 18. 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. 19.
