3. HARDWARE SETUP 8) Floppy Disk Drive Connector (34-1pin FLOPPY) This connector supports the provided floppy drive ribbon cable. After connecting the single end to the board, connect the two plugs on the other end to the floppy drives. (Pin 5 is removed to prevent inserting in the wrong orientation when using ribbon cables with pin 5 plugged). FLOPPY PIN 1 NOTE: Orient the red markings on ® the floppy ribbon cable to PIN 1. 3. H/W SETUP Connectors P4T P4T Floppy Disk Drive Connector 9) Chassis (PCI_FAN), CPU (CPU_FAN), Power Supply (MAIN_FAN) Fan Connectors (3 pins) These connectors support cooling fans of 350mA (4.2 Watts) or less. Orientate the fans so that the heat sink fins allow airflow to go across the onboard heat sink(s) instead of the expansion slots. Depending on the fan manufacturer, the wiring and plug may be different. The red wire should be positive, while the black should be ground. Connect the fan's plug to the board taking into consideration the polarity of the connector. NOTE: The "Rotation" signal is to be used only by a specially designed fan with rotation signal. The Rotations per Minute (RPM) can monitored using a utility such as ASUS PC Probe or Intel LDCM. WARNING! The CPU and/or motherboard will overheat if there is no airflow across the CPU and onboard heatsinks. Damage may occur to the motherboard and/or the CPU fan if these pins are incorrectly used. These are not jumpers, do not place jumper caps over these pins.
