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 Lenovo Dynamic System Analysis for information about testing the server and Running DSA Preboot diagnostic programs for additional information about running DSA Preboot program. For additional information to help you solve problems, see Start here.

If you have just added new software or a new optional device and the server is not working, complete the following steps 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.
  2. Remove the software or device that you just added.
  3. Run Lenovo Dynamic System Analysis (DSA) to determine whether the server is running correctly (for information about using DSA, see Lenovo Dynamic System Analysis).
  4. Reinstall the new software or new device.
