Automated service request (call home)
Lenovo provides tools that can automatically collect and send data or call Lenovo Support when an error is
detected. These tools can help Lenovo Support speed up the process of diagnosing problems.
The following sections provide information about the call home tools.
Lenovo Electronic Service Agent
Lenovo Electronic Service Agent monitors, tracks, and captures system hardware errors and hardware and
software 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
Lenovo website.
For more information and to download Lenovo 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) error codes” on page 805, Appendix A “Integrated Management Module 2.1
(IMM2.1) error messages” on page 229, and Appendix C “DSA diagnostic test results” on page 829 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 “Lenovo Dynamic System Analysis” on page
60 for information about testing the server and “Running DSA Preboot diagnostic programs” on page 61 for
additional information about running DSA Preboot program. For additional information to help you solve
problems, see “Start here” on page 49.
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.
Step 2. Remove the software or device that you just added.
Step 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” on page 60).
Step 4. Reinstall the new software or new device.
