5. IEEE 1394a port connector (10-1 pin IE1394_2)
This connector is for a IEEE 1394a port. Connect the IEEE 1394a module
cable to this connector, then install the module to a slot opening at the back
of the system chassis.
Never connect a USB cable to the IEEE 1394a connector. Doing so will damage
the motherboard!
You can connect the 1394 cable to ASUS Q�Connector (1394, red) first, and
then install the Q-Connector (1394) to the 1394 connector onboard.
6. Thermal sensor cable connectors (2-pin OPT_TEMP1/2/3)
These connectors are for temperature monitoring. Connect the thermal
sensor cables to these connectors and place the other ends to the devices
which you want to monitor temperature. The optional fan1/2/3 can work with
the temperature sensors for a better cooling effect.
The thermal sensor cable is purchased separately.
Enable OPT1/2/3 Cable Overheat Protection in BIOS if you connect thermal
sensor cables to these connectors. Refer to page 4-38 for details.
