4-2.1 Front Panel Switch Header
Reset Button (2-pin RST)
This 2-pin connector connects to the chassis-mounted reset switch for rebooting your computer without
turning your power switch off and on. This is a preferred method of rebooting your system to prolong
the life of your system’s power supply.
Hard Disk Activity LED (2-pin HDD_LED)
This connector supplies power to the chassis's HDD/IDE activity LED. Read and Write activity by
devices connected to the Primary or Secondary IDE connectors will cause the front panel LED to light
up.
ACPI LED
ACPI function allows the system to enter or resume from the Suspend mode. If your system chassis
does not have this button, the same function may be performed from your OS; if it is supported.
Power On Switch
This switch connects to the system’s Power button allowing you to power on and off the system. You
can configure the system to use the keyboard or mouse to power-on the system. You can also
configure the system to respond to power restoration after a power outage occurs. These functions can
be configured by making appropriate settings in the Integrated Peripherals submenu (“Super IO
Device” field) of the BIOS.
Speaker Connector
This connects to the PC speaker installed in the system chassis.
Power LED Connector
This connector connects to the system’s Power LED. When the system’s power is on, this LED will light.
