This chapter provides information on using Standalone or Online Diagnostics to help you
solve hardware problems.
Problem Determination Using the Standalone or Online
Diagnostics
Use this procedure to obtain a service request number (SRN) when you are able to load the
Standalone or Online Diagnostics. If you are unable to load the Standalone or Online
Diagnostics, go to ”Problem Determination When Unable to Load Diagnostics” on page
8-7. The service organization uses the SRN to determine which field replaceable units
(FRUs) are needed to restore the system to correct operation.
