Step 3. Is there a readable image on the monitor screen?
• No: Find the failure symptom in “Troubleshooting by symptom” on page 61; if necessary, see
“Solving undetermined problems” on page 72.
• Yes: Run DSA. See “Running DSA Preboot diagnostic program” on page 59.
– If DSA reports an error, follow the instructions in Appendix C “DSA diagnostic test results” on
page 503.
– If DSA does not report an error but you still suspect a problem, see “Solving undetermined
problems” on page 72.
Diagnostic tools
The following tools are available to help you diagnose and solve hardware-related problems.
• Light path diagnostics
Use light path diagnostics to diagnose system errors quickly. For more information, see “Light path
diagnostics” on page 53.
• Event logs
The event logs list the error codes and messages that are generated when an error is detected. For
more information, see “Event logs” on page 56.
• Integrated Management Module II (IMM2)
The Integrated Management Module II (IMM2) combines service processor functions, video controller,
and remote presence and blue-screen capture features in a single chip. The IMM2 provides advanced
service-processor control, monitoring, and alerting function. If an environmental condition exceeds a
threshold or if a system component fails, the IMM2 lights LEDs to help you diagnose the problem, records
the error in the IMM2 event log, and alerts you to the problem. Optionally, the IMM2 also provides a virtual
presence capability for remote server management capabilities. The IMM2 provides remote server
management through the following industry-standard interfaces:
– Intelligent Platform Management Protocol (IPMI) version 2.0
– Simple Network Management Protocol (SNMP) version 3
– Common Information Model (CIM)
– Web browser
