III.HARDWARE SETUP

7.Chassis,CPU,&PowerSupplyFanConnectors(3-pinCHA_,CPU_,PWR_FAN) These connectors support cooling fans of 500mA (6 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 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! These connectors have power. Damage may occur to the mother- board and/or the CPU fan if these connectors are incorrectly used.

8.Wake-On-LAN Connector (3-pin WOL_CON)

This connector connects to a LAN card with a Wake-On-LAN output, such as the ASUS PCI-L101. The LAN card powers up the system when a wakeup packet or signal is received from the network.

IMPORTANT: This feature requires that the WAKE On LAN Power Up Con- trol is set to Enabled (see Power Management Setup under BIOS SETUP) and that your system has an ATX power supply with at least 720mA +5V standby power.
