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.
