1.3.1 Front Panel Connector (PANEL)

Speaker Connector (SPEAKER)

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) (Disabled)

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.
