v Successful completion of POST (see “POST” on page 184 for moreinformation)v Successful completion of startup, which is indicated by a readable displayof the operating-system desktop3. Is there a readable image on the monitor screen?v No: Find the failure symptom in “Troubleshooting by symptom” on page190; if necessary, see “Solving undetermined problems” on page 208.v Yes: Run DSA (see “Running the DSA Preboot diagnostic programs” on page187).– If DSA reports an error, follow the instructions in Appendix B, “DSAdiagnostic test results,” on page 335.– If DSA does not report an error but you still suspect a problem, see“Solving undetermined problems” on page 208.Diagnostic toolsThe following tools are available to help you diagnose and solve hardware-relatedproblems:v Light path diagnosticsUse light path diagnostics to diagnose system errors quickly. See “Light pathdiagnostics” on page 170 for more information.v Event logsThe event logs list the error codes and messages that are generated when anerror is detected for the subsystems IMM2, POST, DSA, and the serverbaseboard management controller. See “Event logs” on page 181 for moreinformation.v Integrated management module IIThe integrated management module II (IMM2) combines service processorfunctions, video controller, and remote presence and blue-screen capture featuresin a single chip. The IMM provides advanced service-processor control,monitoring, and alerting function. If an environmental condition exceeds athreshold or if a system component fails, the IMM lights LEDs to help youdiagnose the problem, records the error in the IMM event log, and alerts you tothe problem. Optionally, the IMM also provides a virtual presence capability forremote server management capabilities. The IMM provides remote servermanagement 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 browserFor more information about the integrated management module II (IMM2), see“Using the integrated management module” on page 150, Appendix D,“Integrated management module II (IMM2) error messages,” on page 493, andthe Integrated Management Module II User's Guide at http://www.ibm.com/support/entry/portal/docdisplay?lndocid=MIGR-5086346..v IBM Dynamic System AnalysisTwo editions of IBM Dynamic System Analysis (DSA) are available fordiagnosing problems, DSA Portable and DSA Preboot:– DSA Portable168 System x3750 M4 Types 8722 and 8733: Installation and Service Guide
