Performing the checkout procedure
Use this information to perform the checkout procedure.
To perform the checkout procedure, complete the following steps:
Step 1. Is the server part of a cluster?
• No: Go to Step 2 on page 113.
• Yes: Shut down all failing servers that are related to the cluster. Go to Step 3 on page 113.
Step 2. Complete the following steps:
a. Check the power supply LEDs (see “Power-supply LEDs” on page 119).
b. Turn off the server and all external devices.
c. Check all internal and external devices for compatibility at
http://www.lenovo.com/us/en/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 127.
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 115).
i. Check for the following results:
• Successful completion of POST (see “POST” on page 124 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 127; if necessary, see
“Solving undetermined problems” on page 141.
• Yes: Run DSA (see “Running DSA Preboot diagnostic programs” on page 126).
– If DSA reports an error, follow the instructions in Appendix C “DSA diagnostic test results” on
page 549.
– If DSA does not report an error but you still suspect a problem, see “Solving undetermined
problems” on page 141.
