Performing the checkout procedure

Use this information to perform the checkout procedure.

1. Is the server part of a cluster?
   • No: Go to step 2.
   • Yes: Shut down all failing servers that are related to the cluster. Go to step 2.
2. Complete the following steps:
   1. Check the power supply LEDs (see Power-supply LEDs).
   2. Turn off the server and all external devices.
   3. Check all internal and external devices for compatibility at https://static.lenovo.com/us/en/serverproven/index.shtml.
   4. Check all cables and power cords.
   5. Set all display controls to the middle positions.
   6. Turn on all external devices.
   7. Turn on the server. If the server does not start, see Troubleshooting by symptom.
   8. Check the system-error LED on the operator information panel. If it is flashing, check the light path diagnostics LEDs (see Light path diagnostics).
      Note

      When you slide the light path diagnostics panel out of the server to check the LEDs or checkpoint codes, do not run the server continuously with light path diagnostics panel outside of the server. The panel should only be outside of the server a short time. The light path diagnostics panel must remain in the server when the server is running to ensure proper cooling.
   9. Check for the following results:
      • Successful completion of POST (see UEFI/POST for more information)
      • Successful completion of startup, which is indicated by a readable display of the operating-system desktop
3. Is there a readable image on the monitor screen?
   • No: Find the failure symptom in Troubleshooting by symptom; if necessary, see Solving undetermined problems.
   • Yes: Run DSA (see Running the DSA Preboot diagnostic programs).
     • If DSA reports an error, follow the instructions in DSA diagnostic test results.
     • If DSA does not report an error but you still suspect a problem, see Solving undetermined problems.
