Check the following list of
possible causes if the adapter is
unable to communicate on the
network but other stations on the
network are able to
communicate:
v Verify that the appropriate
adapter cable is connected to
the adapter and to the
network.
v Verify that the adapter is firmly
seated in the expansion slot.
v Verify that the setting for the
adapter's Data Rate option
matches the data rate of the
network, or that the data rate
has been set to AutoSense if
yours is not the first station on
the ring.
v Replace the adapter cable
with one that is known to be
good.
v Go to the next step to run the
Token Ring diagnostics. If the
tests are completed
