Maintenance 6-5

Cleaning the Floppy Disk Drive

A read/write error may occur due to stains on the read/write head of the floppy disk drive.

Use the cleaner dedicated for floppy disk drive to clean the read/write head. It is recommended to clean the head on regular basis.

Cleaning CD-ROM

A dusty CD-ROM or dust-accumulated tray causes the device to fail to read data correctly.

Follow the procedure below to clean the tray and CD-ROM regularly:

1.Make sure that the server is powered on.

2.Press the Eject button on the front of the CD-ROM drive. The tray comes out.

3.Hold the CD-ROM lightly and take it out from the tray.

IMPORTANT:

Do not touch the signal side of the CD-ROM with your hand.

4.Wipe the tray with a dry soft cloth.

IMPORTANT:

Do not wipe the lens of the CD-ROM drive. Doing so may damage the lens and may cause a malfunction of the drive.

5.Gently push on the tray front to close the tray.

6.Wipe the signal side of the CD-ROM with a dry soft cloth.

IMPORTANT:

Wipe CD-ROMs from the center to the outside. Use only CD-ROM cleaner if necessary. Cleaning a CD-ROM with record spray/cleaner, benzene, or thinner causes damage to the CD-ROM contents. At worst, inserting the CD-ROM into the server may cause failure.
