Step 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.
Step 2. Complete the following steps:
a. Check the power supply LEDs (see “Power-supply LEDs” on page 24).
b. Turn off the server and all external devices.
c. Check all internal and external devices for compatibility at http://www.lenovo.com/
serverproven/.
d. Check all cables and power cords.
e. Set all display controls to the middle positions.
f. Turn on all external devices.
g. Turn on the server. If the server does not start, see “Troubleshooting by symptom” on page 141.
h. Check the system-error LED on the operator information panel. If it is flashing, check the light
path diagnostics LEDs (see “Light path diagnostics” on page 127).
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.
i. Check for the following results:
• Successful completion of POST (see “UEFI/POST” on page 138 for more information)
• Successful completion of startup, which is indicated by a readable display of the
operating-system desktop
Step 3. Is there a readable image on the monitor screen?
• No: Find the failure symptom in “Troubleshooting by symptom” on page 141; if necessary, see
“Solving undetermined problems” on page 156.
• Yes: Run DSA (see “Running the DSA Preboot diagnostic programs” on page 139).
– If DSA reports an error, follow the instructions in Appendix C “DSA diagnostic test results” on
page 855.
– If DSA does not report an error but you still suspect a problem, see “Solving undetermined
problems” on page 156.
