Front Panel Connector

The front panel connector (PANEL1) provides a standard set of switch and LED connec-
tors commonly found on ATX or micro-ATX cases. Refer to the table below for informa-

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.
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.
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.
Make sure to connect a 4-pin ATX power cable
to ATX4P1; otherwise, the system will be un-
stable.
