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 (the POWER/SLEEP LED is lit).
2. Press the CD tray Open/Close button on the front of the CD-ROM drive.
The tray opens.
3. Hold the CD-ROM lightly and take it out from the tray.
NOTE: 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. 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.
