Troubleshooting Tips
WARNING Before removing a cover, always disconnect the AC power cord and unplug cables.
Disconnect the AC power cord to avoid exposure to high energy levels that may
cause burns when parts are short-circuited by metal objects such as tools or jewelry.
CAUTION Do not operate the HP Server for more than 5 minutes with any cover (including disk drives)
removed. Damage to system components may result due to improper cooling airflow.
For problems with an optional disk array controller board, refer to the appropriate manuals provided with
the array controller.
For questions on the operation of HP e-DiagTools, refer to the HP e-DiagTools Administrator Guide on the
HP Web Site at http://docs.hp.com.
For general information on HP Server products, refer to the HP Web Site and search for “management” at

Troubleshooting Methodology
Step 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 Machine Check Abort
(MCA) has occurred. The following is a list of symptom examples:
System LED blinking
System alert present on console
System will not power-up
System will not boot
Error/event message received
Machine check abort (MCA) occurred
Step 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 server so that you can perform more detailed
troubleshooting. For example:
Problem-System LED blinking
System Alert on console?
