. HW Setup Motherboard
Chassis Intrusion Photo Sensor
This motherboard has a photo sensor onboard, which detects extreme levels
of light entering the chassis such as when the chassis is opened, and sends a
signal to the ASMA software in such an event. To enable this function,
Jumper18 must be set to Enable and an external battery must be connected
to the motherboard’s external battery connector. If you want to work on the
inside of the chassis when an external battery is connected, you should dis-
able Jumper18 to save the battery power.
Panel Connections
Several wires should be connected to the motherboard for the IDE/SCSI
activity, power, and message indicators on the front panel. Panel connec-
tions also allow for an ATX power button, reset switch, and speaker. Con-
nect the chassis front panel wires as illustrated:
