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, and Diagnostic error messages for more information about testing the server. 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.
  2. Remove the software or device that you just added.
  3. Run Lenovo ThinkServer Diagnostics Tool to determine whether the server is running correctly (for information about using Lenovo ThinkServer Diagnostics Tool, see Diagnostic error messages).
  4. Reinstall the new software or new device.
