Chassis Intrusion Switch Connector: JCI1
This connector connects to the chassis intrusion switch cable. If the chassis is
opened, the chassis intrusion mechanism will be activated. 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.
Fan Power Connectors: CPUFAN1, SYSFAN1, SYSFAN2
The fan power connectors support system cooling fan with +12V. When connecting
the wire to the connectors, always 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.
