III. INSTALLATION (Connectors) III. INSTALLATION 9. Turbo LED lead (CON1) The motherboard's turbo function is always on. The turbo LED connection is labeled here but the LED will remain constantly lit while the system power is on. You may wish to connect the Power LED from the system case to this lead. See the figure below. 10. SMI suspend switch lead (CON1) 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 wake-up (the SMI lead cannot wake-up the system). If you want to use this connector, "Suspend Switch" in the POWER MANAGEMENT SETUP of the BIOS software should be on the default setting of Enable (see page 38). 11. Reset switch lead (CON1) 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. See the figure below. 12. Keyboard lock switch lead (CON1) This 5-pin connector connects to the case-mounted key switch for locking the keyboard for security purposes. See the figure below. 13. Speaker connector (CON1) This 4-pin connector connects to the case-mounted speaker.
