General
The Symptom Charts included in this chapter will help you
diagnose specific symptoms related to your product. Because cures
are listed on the charts in the order of most likely solution, try
the first cure first. Verify whether or not the product continues to
exhibit the symptom. If the symptom persists, try the next cure.
(Note: If you have replaced a module, reinstall the original module
before you proceed to the next cure.)
For additional assistance, contact Apple Technical Support.

the popup menu. Restart the computer and then open the
Chooser to check the available services.
3 If you can access some services but can’t access a particular
service, the device providing that service might be located in
a different AppleTalk zone, or it might be malfunctioning,
switched off, or disconnected from the network. There may
also be a break somewhere in the network cables between
your Macintosh and the missing service.
1 There may be more than one Token Ring card installed. Select
the slot number of the card you want to use.
2 There may be earlier versions of the TokenTalk software on
the system. Open the Extensions folder and drag older
