Troubleshooting Overview
Token Ring problems can be caused by problems in a variety of hardware
and software components. The problem impacting your system may
originate in another part of the Token Ring network.
As with any troubleshooting, a systematic approach is helpful. The
following flowcharts provide a logical sequence of steps to follow when
troubleshooting Token Ring. Using the diagnostic flowcharts provided in
this chapter, identify whether the problem is with Token Ring or any of
the connections to the TAU, or whether it is in some other part of the
Token Ring network, verify your assumptions and, if it is limited to
Token Ring software and hardware, correct the problem.
If you cannot solve the problem on your own, contact your HP
representative. Use the guidelines at the end of this chapter to help you
effectively communicate what is wrong.
NOTE To quickly isolate and diagnose Token Ring problems, follow the steps in
the troubleshooting flowcharts in sequence, beginning with flowchart 1,
and stay with the flowcharts until the problems are resolved.
