III. INSTALLATION

9. Chassis Fan, CPU Cooling Fan, & Power Supply Fan Connectors (FANPWR)

These connectors support cooling fans of 500mAmp (6Watt) 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 consid-

eration the polarity of the this connector. NOTE: The “Rotation” signal is to

be used only by a specially designed fan with rotation signal.

WARNING: The CPU and/or motherboard will overheat if there is no air-

flow 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.

10. Chassis Open Alarm Lead (CHASSIS)

This lead is for an open chassis monitor. A high level signal to the CHASSIS

lead will indicate to the system that the chassis has been opened. The +5V lead

comes from the onboard button cell battery to retain its function even if the

power cord has been unplugged from the ATX power supply. Be sure that the

load on the +5V lead is minimal to prevent constant battery replacements.
