Performing the checkout procedure
This topic provides instructions on how to perform the checkout procedure to diagnose server hardware
problems.
To perform the checkout procedure, complete the following steps:
Step 1. Is the server part of a cluster?
• No: Go to Step 2 checkout procedure on page 149.
• Yes: Shut down all failing servers that are related to the cluster. Go to Step 2 checkout
procedure on page 149.
Step 2. Complete the following steps:
a. Check the power supply LEDs (see “Power-supply LEDs” on page 158).
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
170.
h. 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 152).
i. Check for the following results:
• Successful completion of POST (see “POST” on page 164 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 170; if necessary, see
“Solving undetermined problems” on page 195.
• Yes: Run DSA (see “Running the DSA Preboot diagnostic programs” on page 166).
– If DSA reports an error, follow the instructions in Appendix B “DSA diagnostic test results” on
page 345.
– If DSA does not report an error but you still suspect a problem, see “Solving undetermined
problems” on page 195.
