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.
Hard Drive Activity LED
Connecting pin one and pin three provides visual indication that data is being read from or written
to the SATA hard drive, while pin 11 and pin 13 shows that of the IDE hard drive. The LED will also
show activity for devices connected to the SATA (hard drive activity LED) connectors.
Power / Sleep / Message Waiting LED
Connecting pin two and pin four to a single or dual-color, front panel mounted LED provides power
on / off, sleep, and message waiting indication.
Reset Switch
Supporting the reset function requires the connection of pin five and pin seven to a momentary-
contact switch that is normally opened. When the switch is closed, the board resets and runs
POST.
Power Switch
Supporting the power on / off function requires the connection of pin six and pin eight to a
momentary-contact switch that is normally opened. The switch should maintain contact for at least
50 ms to signal the power supply to switch on or off. The time requirement is due to internal de-
bounce circuitry. After receiving a power on / off signal, at least two seconds elapse before the
power supply recognizes another on / off signal.
