Diagnostic Information:
The diagnostic information contains the check procedures you use to diagnose and isolate product failures. Diagnostic information consists of:
Start:
This is the starting point for any diagnostic action. Based on high-level symptoms, the information in this check procedure directs you to more detailed procedures to help you resolve the machine failure.
Symptoms, Messages, Error Codes, and Beeps:
The Index of Symptoms, Messages, Error Codes, or Beep lists symptoms and their probable causes, and directs you to the applicable check procedures to help you resolve the machine failure. The index also lists which FRU is the likely cause of the problem.
Check Procedures:
When the Start check procedure sends you to a specific check procedure or the Index of Symptoms, Mesages, Error Codes, or Beeps, turn to that section and perform the steps as instructed. If there are any notes or instructions at the top of the page, read them before you start the procedure.
Carefully read each step of the check procedure and perform the appropriate action as instructed. If you do not remember the location of a specific part or test point, or if you do not remember an adjustment or removal procedure, see the chapter with that information. Always return to the check procedure after you do this. In some cases, you are sent to other check procedures to find the failure.
Diagnostic Aids:
The Diagnostic Aids chapter contains additional information to help you diagnose a failure of a specific part.
Using the Check Procedures:
Failing Parts or Assemblies: The check procedures generally help you trace a problem to one part or assembly. The last step of the specific check procedure you are using indicates that a part or assembly is failing. You should inspect the part or assembly
before you decide to replace it. It might be loose, dirty, or in need of a small repair. The check procedures might lead you to two, or even three, possible failing parts or assemblies. The parts that might be failing are listed in order of the most probable failure.
Measuring Voltages:
Many check procedure steps instruct you to measure voltages on cable plugs and electronic board connectors. If you are asked to measure voltage at several places on a plug or connector, a chart next to or near the instruction indicates the number of the plug or connector, the pin numbers you should measure, the signal name, and the correct voltage for the condition you are measuring. Measure the voltage only at the pins listed in the chart. Remember to set the meter on the correct scale and to put the meter leads in the correct position for the voltage you are asked to measure.
Note:
Use frame ground for the ground reference. Attach the black meter (ground) lead to frame ground, except where specified otherwise.
Diagnostic Aids:
This chapter contains information outside the check procedures to help you diagnose a failure of a specific part. Some diagnostic aids are resident in the machine, such as the Power-On Self Test (POST). The machine performs the POST each time it is powered
on. Use this information throughout the diagnostic procedures. You should become familiar with the POST and be able to determine if the machine performed all the steps.
POST:
The normal POST is initiated automatically each time the system unit is powered on (when Rapid Resume is enabled, a shorter version of POST is initiated - see ¿Rapid Resume— on page 21). The POST is a series of system checks and initializations that verify the correct operation of the base system. Two classifications of malfunctions might be detected during the POST: critical and noncritical.
Critical malfunctions prevent the system from operating at all, or could cause incorrect results that are apparent to the user. Examples of critical errors include processor or interrupt controller malfunctions. If a critical error is detected during the POST, an attempt is made to indicate the error, and all testing halts.
Noncritical malfunctions cause incorrect results that might not be apparent to the user. An example of a noncritical error is a memory module failure. If a noncritical error occurs, an error code is displayed, and the testing is stopped. Testing can be continued on a noncritical error by pressing the Esc key.
After a successful POST (one in which no critical errors were detected), a single short beep is generated. The system attempts to load an operating system. The system can be customized for different start (boot) methods.
The system's default startup sequence automatically looks for the operating system files on the hard disk if the files are not found on diskette.
Note:
Remember that the POST does not test all areas, but only those that allow the system to operate well enough to run the Advanced Diagnostics program.
Repair Information:
This chapter contains removal and replacement instructions.
Parts/Test Point Locations:
This chapter contains system board layouts and jumper settings. It is useful when you are asked to measure voltages. Use this information to help you locate parts such as electronic boards, connectors, pin numbers, and test points. This chapter also contains jumper and dual in-line package (DIP) switch settings for modems, and jumper settings for the hard disk drive, CD-ROM (compact discýread-only memory) drive, and sound adapter card.
Safety Inspection Guide:
This chapter contains guidelines to help you identify possible safety concerns. Use this information to inspect a machine for safety problems before putting the machine under a Maintenance Agreement.
Parts Catalog:
This catalog includes figures, part numbers, and part names. It also contains detailed system board descriptions.
Part Number Index:
This chapter contains part numbers listed in numerical order.
Appendix: Model Configurations and FRU Part Numbers
This appendix contains tables, listed by country, of models and FRU part numbers. Refer to this when ordering FRUs or to determine the part number of the system board or SIMM installed in the machine you are servicing.
