Failure to do so may result in electric shock.

To Install the Drive

Unplug your computer from the AC power outlet.

female connector.

Install the drive into an available drive bay.

Connect the floppy disk interface cable to the signal
interface connector at the rear of the drive, as illustrated.

Notes

• Make sure that the pin #1 indicator strip of the floppy disk interface cable (usually red

or blue) is aligned with pin #1 of the 34-pin female connector at the rear of the drive.

• To assign the drive as your computer’s A: drive, connect connector A to the signal

interface connector. To assign the drive as your computer’s B: drive, connect connector
