Troubleshooting 58
Be sure each device is properly seated.
If a device has latches, be sure they are completely closed and locked.
Check any interlock or interconnect LEDs that may indicate a component is not connected properly.
If problems continue to occur, remove and reinstall each device, checking the connectors and sockets
for bent pins or other damage.
Diagnostic steps
To effectively troubleshoot a problem, HP recommends that you start with the first flowchart in this section,
"Start diagnosis flowchart (on page 58)," 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 59)." 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 58)
General diagnosis flowchart (on page 59)
Power-on problems flowchart (on page 60)
POST problems flowchart (on page 62)
OS boot problems flowchart (on page 65)
Server fault indications flowchart (on page 66)
The number contained in parentheses in the flowchart boxes corresponds to a table with references to
other detailed documents or troubleshooting instructions.
