Troubleshooting 137
Diagnostic steps
To effectively troubleshoot a problem, HP recommends that you start with the
first flowchart in this section, "Start diagnosis flowchart (on page 137
)," 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 139)." 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 137)
• General diagnosis flowchart (on page 139
)
• Power-on problems flowchart (on page 141)
• POST problems flowchart (on page 144)
• OS boot problems flowchart (on page 146
)
• Server fault indications flowchart (on page 148)
The number contained in parentheses in the flowchart boxes corresponds to a
table with references to other detailed documents or troubleshooting instructions.
