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 “Problem Determination When Unable to Load Diagnostics”
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 “Chapter 5. Using the Standalone and
Online Diagnostics” on page 107.
vISA adapters cannot be detected by the system. The ISAadapter Configuration
Service Aid allows the identification and configuration of ISAadapters for Stand-alone
Diagnostics. ISA adapters must be identified and configured before they can be
tested.
vGo to “Step 2”.

Step 2

Are the Online Diagnostics installed on this system?
NO Go to “Step 15” on page 154.
YES Go to “Step 3” on page 150.
