Troubleshooting flowcharts

To effectively troubleshoot a problem, HP recommends that you start with the first flowchart in this section, "Start diagnosis flowchart (on page 61)," and follow the appropriate diagnostic path. If the other flowcharts do not provide a troubleshooting solution, follow the diagnostic steps in "General diagnosis flowchart (on page 62)." The General diagnosis flowchart is a generic troubleshooting process to be used when the problem is not server-specific or is not easily categorized into the other flowcharts.

The available flowcharts include:

Start diagnosis flowchart (on page 61)

General diagnosis flowchart (on page 62)

Server power-on problems flowchart ("Power-on problems flowchart" on page 64)

POST problems flowchart (on page 66)

OS boot problems flowchart (on page 68)

Server fault indications flowchart (on page 69)
