Chapter 8. Hardware Problem Determination

If you have an error or failure on your system, this chapter contains steps for obtaining a service
request number (SRN). You report the SRN to the service organization. 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 Performing This Procedure
Note: See the operator manual for your type of tty terminal to find the key sequences you
The diagnostic programs use the console terminal attached to the S1 port.
This procedure asks you to select the mode you want to run the diagnostic programs in
(standalone, maintenance, or concurrent). If you need more information about the modes, see
"Diagnostic Modes of Operation" on page 5-7.
If the procedure instructs you to stop the operating system, refer to Chapter 2 for additional
