This chapter provides troubleshooting instructions used in the maintenance of the hp Integrity rx1620
Server.
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
http://docs.hp.com.
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?
