HP ProLiant DL320 G5 Server - Manual (Page 69)

Troubleshooting 69
• If a fixed cable tray is available for the server, be sure the cords and cables connected to the server
are routed correctly through the tray.
• Be sure each device is properly seated. Avoid bending or flexing circuit boards when reseating
components.
• 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 69 )," 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 70 )." 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 69 )
• General diagnosis flowchart (on page 70 )
• Power-on problems flowchart (" Server power-on problems flowchart " on page 72 )
• POST problems flowchart (on page 75 )
• OS boot problems flowchart (on page 76 )
• Server fault indications flowchart (on page 78 )
The number contained in parentheses in the flowchart boxes corresponds to a table with references to
other detailed documents or troubleshooting instructions.
