Apple AppleShare IP 5.0 Update - Manual (Page 11)

Protect your serial number
To use AppleShare IP, you need to provide the unique serial number listed on
your AppleShare IP serial number card, included with your AppleShare IP
materials.
The serial number card is the only record of the serial number provided to
you by Apple—keep it safe and prevent its unauthorized use. You may wish
to make a photocopy of the card and keep the copy in a different location
from the original.
For convenience, the serial number card contains a small adhesive label with
your serial number. You can attach the label directly to your computer, in an
inconspicuous place, or on a page of your AppleShare IP Administrator’s
Manual, but do so only if the label will remain in a safe,
locked location.
WARNING Don’t put the adhesive label on your AppleShare IP
CD-ROM disc (or any other CD-ROM or floppy disk). The label could
come loose while inside a CD-ROM drive and damage the drive.
