Troubleshooting Overview

As with any troubleshooting process, a systematic approach is helpful. The following table and flowcharts provide a logical sequence of steps to follow when troubleshooting either Gigabit or Fast Ethernet.

Using the diagnostic flowcharts:

Identify whether the problem is with Ethernet or any of the connections to the switch, or if the problem is in some other part of the network.
Verify your assumptions.
If the problem is limited to Ethernet software or hardware, use the diagnostic flowcharts in this chapter to help identify and fix the problem.




	NOTE: To help ensure operation without degraded performance, make sure that both link partners are set to autonegotiate, or, if using manual settings, that each side is set to the same speed and duplexity.

If you cannot solve the problem on your own, call your HP representative. Use the guidelines at the end of Chapter 6 to help you effectively communicate what is wrong. The Ethernet products use diagnostic tools compatible with the HP LAN Link product.
