III. INSTALLATION
7. Chassis, CPU , & Power Supply Fan Connectors (3-pin CHA_, CPU_, PWR_FAN)
These connectors support cooling fans of 500mAMP (6 Watts) or less. Orien-
tate 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 this connector. NOTE: The “Rotation” sig-
nal 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 SOFT-
WARE section) and that your system has an ATX power supply with at least
720mA +5V standby power.
