Diagnostic tools overview
The following tools are available to help you diagnose 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 “POST beep code descriptions” on page 52 for more information.

The table in “ServerGuide problems” on page 54 lists problem symptoms and
steps to correct the problems.
v
Troubleshooting charts
The “Troubleshooting charts” on page 55 list problem symptoms and steps to
correct the problems.

Diagnostic programs and error messages
Real Time Diagnostics tests the major components of the BladeCenter unit,
including the management modules, I/O-modules, removable media drives, and
the blade servers, while the operating system is running. Real Time Diagnostics
can be plugged into an existing IBM Director environment or installed without
IBM Director present. For documentation and download information for Real Time
Diagnostics, see http://www.ibm.com/servers/eserver/xseries/
systems_management/xseries_sm.html.
Note: See the Problem Determination and Service Guide for your blade server
type for more information.
