Hypothetical Troubleshooting Scenario
The following describes a hypothetical troubleshooting scenario that might occur with your hp Integrity
cx2600 Server.
1. This is the entry point to the troubleshooting process. Here, you pick from a set of symptoms, ranging
from very simple (system LED is blinking) to the most difficult (MCA has occurred). The following is a list
of symptom examples:
• System LED blinking
• System will not power up
• System will not boot
• Machine check abort (MCA) occurred
2. This step narrows down the observed problem to the specific troubleshooting procedure required. Here,
you isolate the failure to a specific part of the machine so that you can perform more detailed
troubleshooting. For example:
• Problem—System LED blinking yellow or red
— If the LED corresponds to a system alert message on the control console, analyze recent errors
logged by the management processor.
— If the diagnostic LEDs identify a probable cause, analyze the logged error messages for additional
information.
3. At this point you will probably know which component of your HP Server needs attention. For example, if
the symptom was “System won’t power up” the initial troubleshooting procedure may have led to a
problem with the power supplies.
4. You have now reached the point where the failed Field Replaceable Unit (FRU or FRUs) have been
identified and need to be replaced. You must now perform the specific remove and replace and verification
steps. See the hp Integrity cx2600, Operation and Maintenance Guide on the documentation CD included
with your system for remove and replace procedures on all FRUs in your HP Server.
NOTE If multiple FRUs are identified as part of the solution, a fix may not be complete unless all
identified failed FRUs are replaced.
5. There may be specific recovery procedures you need to perform to finish the repair. For example, if the
management processor is replaced, you will need to restore customer-specific information such as user
profiles, network IDs, and passwords. See the hp Integrity cx2600, Operation and Maintenance Guide on
the documentation CD included with your system for procedures on setting up your management
processor.
