You have stations that are not indicated on any
status screen presentation, or by a cluster-access
error message.
1. Do the system diagnostic tests on a station
that is not indicated on any status screen
presentation, or that has a cluster-access
error.
2.
If
the diagnostic test fails, have the unit that
contains the adapter serviced.
3.
If
the diagnostic test passes, continue doing
the diagnostic tests until you test all of the
stations that did not appear on any status
screen presentation or that had a
cluster-access error.
4.
If
the Cluster Adapters check good and the
stations did not appear on the cluster-status
screen presentations, notify your installation
manager that you suspect the coaxial cable or
a terminating plug.
Note: If
you have more than one Cluster
Adapter installed in your system, go back to
page 2200-1 and continue until all Cluster
Adapters are tested.
