IBM RS/6000 44P manual Hardware Problem Determination, Step

Chapter 8. Hardware Problem Determination

This chapter provides information on using stand-alone or online diagnostics to help you solve hardware problems. In addition, it provides a list of error codes and recommended actions that you can take to resolve the problem before contacting a service representative.

Problem Determination Using the Stand-alone or Online Diagnostics

Use this procedure to obtain a service request number (SRN) when you are able to load the Stand-alone or Online Diagnostics. If you are unable to load the Stand-alone or Online Diagnostics, go to ªProblem Determination When Unable to Load Diagnosticsº on page 156. The service organization uses the SRN to determine which field replaceable units (FRUs) are needed to restore the system to correct operation.

Step 1. Considerations before Running This Procedure

Note: See the operator manual for your ASCII terminal to find the key sequences you need to respond to the diagnostic programs.

vThe diagnostics can use a display connected to the video port or an ASCII terminal attached to a serial port.

vThis procedure asks you to select the type of diagnostics you want to run. If you need more information about the types, see ªChapter 5. Using the Standalone and Online Diagnosticsº on page 107.

vISA adapters cannot be detected by the system. The ISA adapter Configuration Service Aid allows the identification and configuration of ISA adapters for Stand-alone Diagnostics. ISA adapters must be identified and configured before they can be tested.

vGo to ªStep 2º.

Step 2
