Remove and check all data and power cables for damage. Be sure no cables have bent pins or
•
damaged connectors.
If a fixed cable tray is available for the server, be sure the cords and cables connected to the server
•
are correctly routed through the tray.
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 66)," 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 67)." 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:
