Methodology
General Troubleshooting Methodology
There are multiple entry points to the troubleshooting process, depending on your level of
troubleshooting expertise; the tools, processes, and procedures available, and the type of system
fault or failure.
Typically, you select from a set of symptoms, ranging from very simple (System LED is blinking)
to the most difficult (Machine Check Abort, for example, MCA, has occurred). The following is
a list of symptom examples:
• Front Panel LED blinking
• System Alert present on console
• System will not power on
• System will not boot
• Error or event message received
• Machine Check Abort (MCA) occurred
Next, you narrow down the observed problem to isolate the failure to a specific part of the server,
so that you can perform more detailed troubleshooting. For example:
• Problem- Front Panel LED blinking
