NOTE A-Class System Service A-Class Server Trouble Shooting A-Class Server Trouble Shooting Overview Troubleshooting an A-Class server is performed to the "Field Replaceable Unit" (FRU) level. Diagnostic testing can be performed on the A-Class server and most components can be removed and replaced by the customer or customer representative.

A-Class Server Trouble Shooting
Overview
Troubleshooting an A-Class server is performed to the “Field Replaceable Unit” (FRU)
level. Diagnostic testing can be performed on the A-Class server and most components
can be removed and replaced by the customer or customer representative.
NOTE
The information in this section is meant for users who have at least a minimum level of
hardware troubleshooting experience. Some System Administrator-level knowledge of
the HP-UX operating system is also required.
This section gives you the information needed to recognize repeatable hardware failures
that prevent completion of the server selftest, or hardware failures that will not allow
the HP-UX operating system to either initiate or complete the boot procedure.
Use the troubleshooting data and procedures in this section to isolate hardware failures
within the A-Class server. Do not use this information to troubleshoot external
peripheral device problems. Refer to the suspect peripheral's documentation for
troubleshooting assistance.
Procedures for evaluating and describing messages, codes, and indicators are contained
in the subsections listed below:
•
A-Class Server Selftest Failures/Warnings
•
Troubleshooting with Light-Emitting Diode (LED) Interpretation
—
Successful Power-on Selftest.
—
