9-6 Troubleshooting
Defective CD Disc
HP CD-ROM drives for the towers are designed to automatically
switch down to lower speeds when they encounter a defect or a
scratch on the disc, and then to continue to read data at the
slower speed until a new read command is transmitted to the
drive. However, fingerprints, contaminants, or deep scratches on
the disc surface may prevent the drive from successfully reading
data. Perform the disc cleaning procedure on page 2-13.
If the problem persists, test a different disc in the same
drive; if that disc works properly, the previous disc may be
defective. If no disc works properly in the drive, try switch-
ing off the server/tower, wait 10 seconds, and then switch it
on again (power cycle). Wait for Status to go off. Also verify
that the CD is in a supported format (described on page 9-7).
If problem persists, the drive may be faulty; see "Isolate
Faulty Hardware Component" on page 9-17.
Ejected CD Disc
HP CD-ROM drives for HP server/towers are designed to auto-
matically eject any unreadable disc. If a disc is ejected, verify
that the disc is in the tray with the label side towards the top of
the tower (as floor mounted). Or the disc may be blank, incor-
rectly written, or damaged. Also verify that the CD-ROM or
DVD-ROM is in a supported format (CD-DA; CD-ROM Mode 1;
CD-ROM XA Mode 2, Form 1 and Form 2; Multisession Mode 1
and 2; CD UDF—variable packets; CD Extra, CD-G).
Test a different disc in the same drive; if that disc works prop-
erly, the previous disc may be defective. If no disc works prop-
erly in the drive, try switching off the server/tower, wait 10
seconds, and then switch it on again (power cycle). Wait for
Status to go off. If problem persists, the drive may be faulty; see
"Isolate Faulty Hardware Component" on page 9-17.
CD Read or Drive Problem
If the ON/BUSY indicator is flashing 5 times in a series and you
cannot see or access the CD, then open and close the CD tray
door using the Stop/Eject button. Wait to see if the Disc goes on
and ON/BUSY goes off; you should then have access. If that does
not work, try switching off the server/tower, wait 10 seconds,
and switch it on again (power cycle). Wait for Status to go off.
If problem persists, refer to the problems "Defective CD Disc" on
page 9-6 and "Errors when Accessing Server or Discs" on page 9-
