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 123).
b.
Turn off the server and all external devices.
c.
Check all internal and external devices for compatibility at
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
132.
h.
Check the system-error LED on the operator information panel. If it is flashing, check the light
path diagnostics LEDs (see "Server controls, LEDs, and power" on page 16).
i.
Check for the following results:
• Successful completion of POST (see "POST" on page 128 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 132; if necessary, see
"Solving undetermined problems" on page 154.
• Yes: Run DSA (see "Running the DSA Preboot diagnostic programs" on page 130).
– If DSA reports an error, follow the instructions in Appendix C "DSA diagnostic test results" on
page 657.
– If DSA does not report an error but you still suspect a problem, see "Solving undetermined
problems" on page 154.
Diagnostic tools
The following tools are available to help you diagnose and solve hardware-related problems.
• Event logs
The event logs list the error codes and messages that are generated when an error is detected for the
subsystems IMM2, POST, DSA, and the server baseboard management controller. See "Event logs" on
page 125 for more information.
• Integrated Management Module (IMM)
The Integrated Management Module (IMM) combines service processor functions, video controller, and
remote presence and blue-screen capture features in a single chip. The IMM provides advanced service-
processor control, monitoring, and alerting function. If an environmental condition exceeds a threshold or
if a system component fails, the IMM lights LEDs to help you diagnose the problem, records the error in
the IMM event log, and alerts you to the problem. Optionally, the IMM also provides a virtual presence
capability for remote server management capabilities. The IMM provides remote server management
through the following industry-standard interfaces:
– Intelligent Platform Management Protocol (IPMI) version 2.0
