Troubleshooting Overview

Troubleshooting Overview

10/100Base-TX 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 10/100Base-TX network.

As with any troubleshooting, a systematic approach is helpful. The following two tables and the following flowcharts provide a logical sequence of steps to follow when troubleshooting 10/100Base-TX/9000. Using the diagnostic flowcharts provided in this chapter, identify whether the problem is with 10/100Base-TX/9000 or any of the connections to the hub or switch, or whether it is in some other part of the network, verify your assumptions and, if it is limited to 10/100Base-TX/9000 software or hardware, correct the problem.

To quickly isolate and diagnose 10/100Base-TX/9000 problems, follow the steps in the troubleshooting flowcharts, beginning with Flowchart 1, and stay with the flowcharts until the problems are resolved. Continue sequentially through flowcharts 2, 3, 4, 5, 6, and 7, referring back to flowchart 1 (ping) until you have corrected the problems.

If you cannot solve the problem on your own, contact your HP representative. Use the guidelines at the end of chapter 3 to help you effectively communicate what is wrong. T he 10/100Base-TX product uses diagnostic tools compatible with the HP LAN/9000 Link product.
