FRU Isolation
For a list of error codes and recommended actions for each code, see Chapter 5, “Error
Code to FRU Index”, on page 115. These actions can refer to Chapter 10, “Parts
Information”, on page 303, Chapter 3, “Maintenance Analysis Procedures (MAPs)”, on
page 35, or provide informational message and directions. If a replacement part is
indicated, direct reference is made to the part name. The respective AIX and physical
location codes are listed for each occurrence as required. For a list of locations codes,
see “Location Codes” on page 14.
To look up part numbers and view component diagrams, see Chapter 10, “Parts
Information”, on page 303. The beginning of that chapter provides a parts index with the
predominant field replaceable units (FRUs) listed by name. The remainder of the
chapter provides illustrations of the various assemblies and components that make up
the system.
Electronic Service Agent for the RS/6000
Service support for the system can be enhanced through the use of the application
program, Electronic Service Agent for the RS/6000. This application provides a number
of advantages for the customer, including automatic error reporting and analysis without
customer intervention. The Electronic Service Agent kit ships with the system and
includes the following:
v
Electronic Service Agent for the RS/6000 program on CD-ROM
v
The manual Electronic Service Agent for the RS/6000 User’s Guide.
If the manual is not included, it can be downloaded from the following Web site:

Using the Service Processor and Electronic Service Agent Features
The service processor and Electronic Service Agent features protect users against
unnecessary system downtime by advising support personnel (both internal and
external) of any unexpected changes in the system environment. In combination, the
two features provide a flexible solution to automated system maintenance.
Service Processor
The service processor runs on its own power boundary and continually monitors
hardware attributes, the AIX operating system, and the environmental conditions within
the system. Any system failure which prevents the system from coming back to an
operational state (a fully functional AIX operating system) is reported by the service
processor. The service processor is controlled by firmware and does not require the AIX
