Installing an expansion card
If you purchased an expansion card for your Macintosh, install it now.
(See Appendix B, “Installing an Expansion Card,” for instructions.) If you
don’t have an expansion card, continue with the next section, “Connecting
the Modem.”
WARNING
This equipment is intended to be electrically grounded. Your
Macintosh is equipped with a three-wire grounding plug—a plug that
has a third (grounding) pin. This plug will fit only a grounded AC outlet.
This is a safety feature. If you are unable to insert the plug into the
outlet, contact a licensed electrician to replace the outlet with a properly
grounded outlet. Do not defeat the purpose of the grounding plug!
