Diagnostic tools overview
The following tools are available to help you identify and solve hardware-related
problems:
v
POST beep codes
The power-on self-test beep codes indicate the detection of a problem.
– One beep indicates successful completion of POST.
– More than one beep indicates that POST detected a problem. Error messages
also appear during startup if POST detects a hardware-configuration problem.
See “POST beep code descriptions” and the
BladeCenter HS20 Type 8832
Hardware Maintenance Manual and Troubleshooting Guide
on the IBM
BladeCenter Documentation
CD that comes with your BladeCenter unit for more
information.

Diagnostic programs and error messages
The system diagnostic programs are provided in ROM. These programs test the
major components of your blade server. The IBM Director product provides a
real-time diagnostic program that tests the major components of your blade
server, including the BladeCenter CD-ROM drive and diskette drive, while the
server operating system is running. See the documentation for the IBM Director
product on the
IBM Director
CD that comes with the BladeCenter unit for more
information.

during startup, other beep codes might occur. You can use the following beep code
descriptions to help identify and resolve problems that are detected during startup.
