followed.
V
CAUTION!
Only use CDs/DVDs that are in perfect condition in your server's
CD/DVD drive, in order to prevent data loss, equipment damage and

(data loss).
Under certain circumstances, sharp CD/DVD fragments can pierce
the cover of the CD/DVD drive (equipment damage) and can fly out
of the device (danger of injury, particularly to uncovered body parts
such as the face or neck).

tions:
