Troubleshooting by symptom

Use the troubleshooting tables to find solutions to problems that have identifiable symptoms.
If you cannot find a solution to the problem in these tables, see Appendix C "DSA diagnostic test results"
on page 503 for information about testing the server and "Running DSA Preboot diagnostic program" on
page 59 for additional information about running DSA Preboot program. For additional information to help
you solve problems, see "Start here" on page 47.
Notes:
• Follow the suggested actions in the order in which they are listed in the Action column until the problem is
solved.
• If an action step is preceded by '(Trained technician only)', that step must be performed only by a trained
technician.
• Go to the Lenovo support Web site at http://www.lenovo.com/support to check for technical information,
hints, tips, and new device drivers or to submit a request for information.
If you have added new software or a new optional device and the server is not working, do the following
before you use the troubleshooting tables:
Step 1. Check the system-error LED on the operator information panel; if it is lit, check the light path
diagnostics LEDs (see "Light path diagnostics" on page 53).
Step 2. Remove the software or device that you just added.
Step 3. Run Dynamic System Analysis (DSA) to determine whether the server is running properly (see
Appendix C "DSA diagnostic test results" on page 503).
Step 4. Reinstall the new software or new device.
