Diagnostic tools
The following tools are available to help you diagnose and solve hardware-related
problems:
v POST beep codes, error messages, and error logs
v Troubleshooting tables
v Diagnostic programs, messages, and error codes
POST
When you turn on the blade workstation, it performs a series of tests to check the
operation of the blade workstation components and some optional devices in the
blade workstation. This series of tests is called the power-on self-test, or POST.
If a power-on password is set, you must type the password and press Enter, when
prompted, for POST to run.
If POST is completed without detecting any problems, a single beep sounds, and
the blade workstation startup is completed.
If POST detects a problem, more than one beep might sound, or an error message
is displayed. See "Beep code descriptions" on page 40 and "POST error codes" on
page 43 for more information.

BladeCenter unit. Problems with these shared resources might appear to be
in the blade workstation (see "Solving shared BladeCenter resource
problems" on page 75 for information about isolating problems with these
resources). See the Problem Determination and Service Guide or the
Hardware Maintenance Manual and Troubleshooting Guide for your
BladeCenter unit and other BladeCenter component documentation for
diagnostic procedures for shared BladeCenter components.
The power-on self-test (POST) generates beep codes and messages to indicate
successful test completion or the detection of a problem. See "POST" for more
information.
These tables list problem symptoms and actions to correct the problems. See
"Troubleshooting tables" on page 56 for more information.
The diagnostic programs are the primary method of testing the major
components of the blade workstation. These programs are stored in read-only
memory (ROM) on the blade workstation. See "Diagnostic programs, messages,
and error codes" on page 68 for more information.
