III. INSTALLATION 11. Turbo LED Lead (PANEL) 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. This lead should be connected to the Power LED on the system cabinet if your keyboard plug does not have a power LED lead. See the figure below. 12. SMI Suspend Switch Lead (PANEL) 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 cabinet-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 the Power Management Setup of the BIOS SOFTWARE section should be on the default setting of Enable. 13. Reset Switch Lead (PANEL) This 2-pin connector connects to the cabinet-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. 14. Keyboard Lock Switch Lead & System Power LED (PANEL) This 5-pin connector connects to the cabinet-mounted keyboard lock switch for locking the keyboard and also to connect the system power LED. The system power LED lights when the system is powered on. See the figure below. 15. Speaker Connector (PANEL) This 4-pin connector connects to the cabinet-mounted speaker.
