Diagnostic tools overview
The following tools are available to help you identify and solve hardware-related problems:
•
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 “Beep symptoms” on page 69 for more information.

These charts list problem symptoms and steps to correct the problems. See “Error symptoms” on
page 83 for more information.
The built-in system diagnostic programs are upgradeable read-only memory (ROM). These
programs test the major components of your blade server
