Connecting Internal Headers
Front Panel Header
The front panel header on this motherboard is one connector used to connect the following four
cables. (see Table 2 for pin definitions):
PWRLED
Attach the front panel power LED cable to these two
pins of the connector.
The Power LED indicates the system’s status. When the
system is in S0 status, the LED is on. When the system
is in S4, S5 status, the LED is off. When the system is in
S1, S3 status, the LED is blink.
Note: Some chassis do not have all four cables. Be sure to match
the name on the connectors to the corresponding pins.
PWRSW
Attach the power button cable from the case to these
two pins. Pressing the power button on the front panel
turns the system on and off rather than using the power
supply button.
HD_LED
Attach the hard disk drive indicator LED cable to these
two pins. The HDD indicator LED indicates the activity
status of the hard disks.
RESET
Attach the Reset switch cable from the front panel of
the case to these two pins. The system restarts when the
RESET switch is pressed.
