Troubleshooting Overview
Troubleshooting Overview
Troubleshooting FDDI problems can be difficult because a variety of
hardware and software components may be involved and because the
problem affecting your system may originate in another part of the FDDI
network.
As with any troubleshooting, a systematic approach is helpful. The
following flowcharts provide a logical sequence of steps to follow when
troubleshooting HP FDDI/9000. Using the diagnostic flowcharts
provided in this chapter, identify whether the problem is with HP
FDDI/9000 or any of the connections to the concentrator, or whether it is
in some other part of the FDDI network, verify your assumptions and, if
it is limited to HP FDDI/ 9000 software and hardware, correct the
problem.
If you cannot solve the problem on your own, contact your HP
representative. Use the guidelines in chapter 1, “FDDI Resources,” to
help you effectively communicate what is wrong.
NOTE To quickly isolate and diagnose HP FDDI/9000 problems, follow the steps
in the troubleshooting flowcharts in sequence, beginning with Flowchart
1, and stay with the flowcharts until the problems are resolved.
