Electronic Service Agent

inventory information, and reports serviceable problems directly to Lenovo Support.
You can also choose to collect data manually. It uses minimal system resources, and can be downloaded
from the website. For more information and to download Electronic Service Agent, go to

Error messages

This section provides the list of error codes and messages for UEFI/POST, IMM, and DSA that are generated
when a problem is detected.
See Appendix B "UEFI/POST diagnostic codes" on page 715, Appendix A "Integrated management module
II (IMM2) error messages" on page 305, and Appendix C "DSA diagnostic test results" on page 735 for more
information.

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 735 for information about testing the server and "Running the DSA Preboot diagnostic programs" on
page 137 for additional information about running DSA Preboot program. For additional information to help
you solve problems, see "Start here" on page 115.
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:
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 121).
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 correctly (for
information about using DSA, see Appendix C "DSA diagnostic test results" on page 735).
Step 4. Reinstall the new software or new device.
