CD-ROM Drive
Problems
Action
The CD is not working
properly. Clean the CD by wiping it with a soft, lint-free cloth,
from the center of the CD to the outer edge. Do not
clean in a circular pattern. This can cause loss of data.
If this does not correct the problem, clean the
optical-head lens. Discs for cleaning the lens are
available from your place of purchase.
If a problem still exists, have the system serviced.
CD-ROM Drive Tray Not
Working The server must be turned on. If the system is on and
the tray does not eject, insert the end of a paper clip
into the small hole (to the left of the tray load and eject
button) on the front of the CD-ROM drive. If the drive
still does not work correctly, have the system serviced.
CD-ROM drive not
recognized Use the System Configuration Utility to verify that the
CD-ROM drive is enabled and that the SCSI ID is set
correctly.
