Chapter 2. Diagnostic OverviewThe system uses an integrated set of software diagnostic procedures to help isolate failing componentsand system maintenance. This book, along with the RS/6000 Eserver pSeries Diagnostic Information forMultiple Bus Systems, is the basis of the diagnostic procedures for the system. In particular, Chapter 4,“Checkpoints,” on page 131, Chapter 5, “Error Code to FRU Index,” on page 159, Chapter 6, “Using theOnline and Standalone Diagnostics,” on page 217, and Chapter 10, “Parts Information,” on page 365, inthis book are important for the trained service representative to understand and use when isolating afailure on the system.The manufacturer recommends that systems configured with 4 GB of memory or greater have access to a4-mm or 8-mm tape drive for submission of system dump information if required. This function can beaccomplished through locally attached or network-attached devices, as appropriate.Maintenance Analysis Procedures (MAPs)Maintenance Analysis Procedures (MAPs) guide the trained service representative through the system.These MAPs are the entry point for all isolation and error recovery procedures. The MAPs are consistentwith existing procedures and methods. The system uses a set of integrated procedures, mentioned earlier,to which the MAPs are the primary entry point.The MAPS are as follows:v Entry MAPv Quick Entry MAPv MAP 1020: Problem Determination MAPv MAP 1240: Memory Problem Resolutionv MAP 1320: Service Focal Point Proceduresv MAP 1321: Quick Entry MAP for Systems with Service Focal Point. This MAP contains information forsystems not running the AIX operating system.v MAP 1322: End of Call MAP for Systems with Service Focal Pointv MAP 1520: Power MAPv MAP 1521: The Base System Drawer will not Power On and No Error Codes are Availablev MAP 1522: Cannot Power On the I/O Drawer, Power Present LED Does Not Come Onv MAP 1523: The SPCN Error Codes Table Directed You Here and the Error Code is 1011 1B0xv MAP 1540: Problem Isolation Proceduresv MAP 1541: JTAG Problem Isolationv MAP 1548: Processor Subsystem Problem Isolationv MAP 1549: Attention Problem IsolationThe Entry Map is the starting point for problem determination. The purpose of this MAP is to quickly pointto the appropriate MAP or service reference information either in this book, or in the common book set,which includes the RS/6000 Eserver pSeries Diagnostic Information for Multiple Bus Systems and PCIAdapter Placement Reference.The Quick Entry MAP is a subset of the Entry MAP and helps to save time for some types of problems.The Problem Determination MAP provides a structured analysis method to get an error code if one is notprovided by the customer, or if diagnostics cannot be loaded.The Power MAP deals with isolation of components to diagnose a power problem. Power problems can berelated to powering on and powering off the system, or power failures that occur after power is turned on.39
