The mainboard provides connectors to connect to FDD, IDE HDD, case, LAN, USB
Ports, CPU/system power supply fans, ... and etc.

Floppy Disk Drive Connector: JFDD

The mainboard provides a standard floppy disk drive connector that supports 1.44M
and 2.88M floppy disk types.

Chassis Intrusion Switch Connector: JCI1

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

Fan Power Connectors: CPUFAN1/2/3, POWERFAN1/2/3/4

The fan power connectors support system cooling fans with +12V. W hen connect-
ing 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 onboard, you must
use a specially designed fan with speed sensor to take advantage of the CPU fan
control.
