3. Floppy disk drive connector (34-1 pin FLOPPY) This connector supports the provided floppy drive ribbon cable. After connecting one end to the motherboard, connect the other end to the floppy drive. (Pin 5 is removed to prevent incorrect insertion when using ribbon cables with pin 5 plug). FLOPPY PIN 1 P4B-M NOTE: Orient the red markings on the floppy ribbon cable to PIN 1. ® P4B-M Floppy Disk Drive Connector Figure 2-31 Floppy Disk Drive Connector 4. CPU and system fan connectors (3-pin CPUFAN, SYSTEMFAN) The fan connectors support a CPU fan (750mA) and a system fan (500mA) at +12V. Orient the fans so that the heat sink fins allow air flow to go across the onboard heat sinks instead of the expansion slots. The fan wiring and plug may vary depending on the fan manufacturer. Connect the fan cable to the connector matching the black wire to the ground pin. Do not forget to connect the fan cables to the fan connectors. Lack of sufficient air flow within the system may damage the motherboard components. These are not jumpers! DO NOT place jumper caps on the fan connectors!
