Chassis Intrusion Switch Connector: JCI1

This connector is connected to a 2-pin chassis switch. If the chassis is
opened, the switch will be short. The system will record this status and show
a warning message on the screen. To clear the warning, you must enter the
BIOS utility and clear the record.

ISA Bridge Control Connector: JISA1 (Optional)

Fan Power Connectors: SYSFAN2/3

The SYSFAN2/3 (system fans) support system cooling fan with +12V. It
supports three-pin head connector. When connecting the wire to the
connectors, always take note that the red wire is the positive and should be
connected to the +12V, the black wire is Ground and should be connected to
GND. If the mainboard has a System Hardware Monitor chipset on-board, you
must use a specially designed fan with speed sensor to take advantage of the
CPU fan control.
