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 DSA diagnostic test results for information about testing the server and Running DSA Preboot diagnostic program for additional information about running the DSA Preboot program. For additional information to help you solve problems, see Start here.

  • 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 the Lenovo Support Portal 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:

  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).
  2. Remove the software or device that you just added.
  3. Run Dynamic System Analysis (DSA) to determine whether the server is running properly (see DSA diagnostic test results).
  4. Reinstall the new software or new device.
