3. HARDWARE SETUP
14) Message LED Lead (2-pin LED)
This indicates whether a message has been received from a fax/modem. The
LED will remain lit when there is no signal and flash when there is data re-
ceived. This function requires an ACPI OS as well as application and driver
support.
15) Keyboard Lock Switch Lead (2-pin KEYLOCK)
This 2-pin connector connects to the case-mounted key switch to allow key-
board locking.
16) System Management Interrupt Lead (2-pin EXSMI)
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 con-
nects 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 prob-
lems. This may require one or two presses depending on the position of the
switch. The keyboard can always allow wake-up but not the SMI lead.
17) System Warning Speaker Connector (4-pin SPEAKER)
This 4-pin connector connects to the case-mounted speaker. You may leave this
disconnected if you connect the chassis speaker to the INT_SPKA. All three
sources (LINE_OUT, INT_SPKA, SPEAKER) will allow you to here system
beeps and warnings. Only LINE_OUT will allow you to hear system beeps be-
fore the integrated audio has been properly initialized.
18) ATX Power Switch Lead (2-pin PWRSW)
The system power is controlled by a momentary switch connected to this lead.
Pressing the button once will switch the system between ON and SOFT OFF.
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.
19) IDE Activity LED (2-pin HDLED)
This connector supplies power to the cabinet's IDE activity LED. Read and
write activity by devices connected to the Primary or Secondary IDE connectors
will cause the LED to light up.
20) System Power LED Lead (3-1 pin PLED)
This 3-1 pin connector connects the system power LED, which lights when the
system is powered ON and flashes when it is in standby (suspend) mode.
21) 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 to prolong the life of the system's power supply.
