FireWire FireLite AC Adapter
For convenience, your SmartDisk portable hard drive draws its power from a 6-pin FireWire (1394a) port. However, some computers provide 4-pin FireWire ports only. Since 4-pin ports do not supply power, you will need to obtain a 6-4 pin FireWire cable and separate A/C adapter (SmartDisk model ACFWS) to use your SmartDisk hard drive with this computer.
