Front Panel Header
The front panel header (F_PANEL ) provides a standard set of switch and LED
headers commonly found on ATX or Micro ATX cases. Refer to the table below for
information:
Reset Switch
Supporting the reset function requires connecting pin 5 and 7 to a momentary-
contact switch that is normally open. When the switch is closed, the board resets and
runs POST.
Power/Sleep/Message waiting LED
Connecting pins 2 and 4 to a single or dual-color, front panel mounted LED provides
power on/off, sleep, and message waiting indication.
Hard Drive Activity LED
Connecting pins 1 and 3 to a front panel mounted LED provides visual indication
that data is being read from or written to the hard drive. For the LED to function
properly, an IDE drive should be connected to the onboard IDE interface. The LED
will also show activity for devices connected to the SCSI (hard drive activity LED)
connector.
