Introduction This chapter contains the check procedures used to diagnose the causes of product failures. The diagnostic information consists of: Start: This is the starting point for any diagnostic action. Based on high-level symptoms, the check procedure directs you to more detailed procedures to help resolve machine failures.
Start This is the entry point for all check procedures. The check procedures use failure symptoms, Power-On Self Test (POST) error codes, or beeps to help determine the defective field replaceable unit (FRU). Follow the suggested check procedures or use the diagnostics CD to determine the problem FRU. IMPORTANT: Replace FRUs ONLY when it is determined that the error is not a result of software, loose contacts, or dirty component surfaces.
servicing may have been rearranged, or the drive startup sequence has changed. Be extremely careful during write operations, such as copying, saving, or formatting. Data or programs can be overwritten if you select an incorrect drive. Ask the customer to back up any additional software from the hard disk drive before you reload the software. How to Diagnose Combined FRUs: If an adapter or device consists of more than one FRU, any of the FRUs might cause an error code.
• Remove all adapter cards, except for the factoryinstalled adapter cards. • Disconnect all drives except: - Hard disk drive - IBM factory-installed devices (such as a CDROM drive) • Ensure that all power cords and cables are connected properly. • Ensure that the monitor brightness and contrast controls are not turned down. • Power on the system unit. NOTE: Some monitors have a detachable system I/O signal cable between the monitor and the system unit.

NO, GO TO STEP 005) • Go to “Index of Symptoms, Messages, Error Codes, or Beeps” on page 36. • End. 005 - • If the keyboard responds incorrectly, go to “Keyboard” on page 65. • If monitor problems appear, such as jittering, shifting, or being out of focus, go to “Monitor” on page 70. 006 - DOES THE SYSTEM CONFIGURATION REPORT CORRECTLY IDENTIFY THE DEVICES INSTALLED IN SYSTEM? (YES, READ AHEAD. NO, GO TO STEP 007.
- If an error or other symptom is displayed, go to “Index of Symptoms, Messages, Error Codes, or Beeps” on page 36. - If no error can be detected or the symptom is intermittent, go to “Undetermined Problems” on page 72. • End 009 - • If the last test stops and you cannot continue, first make sure all switches, power connectors, cables, and jumpers are set correctly and show the correct voltages and continuity. • Take note of any messages, error codes, beeps, or new symptoms.
Index of Symptoms, Messages, Error Codes, or Beeps How to Use Error Messages: Use the messages, error codes, and beeps combinations that occur to diagnose failures. If more than one failure occurs, begin the diagnosis from the first failure that appeared. The cause of the first failure can result in false messages, error codes, or beeps. If you did not receive any messages, error codes, or beeps, see if the symptom is listed in “Table 2-3 Error Symptoms List” on page 48.
“Action/FRU” column. When servicing a system, always begin with “Start” on page 31. If you are unable to correct the problem using these two index tables, go to “Undetermined Problems” on page 72.
