1.3.1 Front Panel Connector(J1)
J1 PANEL Connector
Speaker Connector (SPKR)
An offboard speaker can be installed onto the motherboard as a
manufacturing option. An offboard speaker can be connected to
the motherboard at the front pannel connector. The speaker
(onboard or offboard) provides error beep code information
during the Power Self-Test when the computer cannot use the
video interface. The speaker is not connected to the audio
subsystem and does not receive output from the audio subsystem.
Hard Drive LED Connector (HD_LED)
This connector supplies power to the cabinet IDE activity LED.
Read and write activity by devices connected to the Primary or
Secondary IDE connectors will cause the LED to light up.
SMI Suspend Switch Lead (EXTSMI)
This allows the user to manually place the system into a suspend
mode of Green mode. 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) connects to the case-mounted suspend switch. If you do
not have a switch for the connector, you may use the "Turbo
Switch” instead since it does not have a function. SMI is
activated when it detects a short. It 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 Suspend Switch Lead cannot wake-up
the system). If you want to use this connector, the "Suspend
Switch" in the Power Management Setup of the BIOS SOFT-
WARE section should be on the default setting of Enable.
