• Do not plug the IEEE 1394 bracket (2x5-pin) cable into the USB header.

• Prior to installing the USB bracket, be sure to turn off your computer and unplug the power

cord from the power outlet to prevent damage to the USB bracket.

When the system is in S4/S5 mode, only the USB ports routed to the F_USB1 header can sup-

port the ON/OFF Charge function.
