These tables list problem symptoms and steps to correct the problems. See
"Troubleshooting tables" on page 70 for more information.
The built-in self-test (BIST) program checks the BladeCenter HT unit during
startup and generates error messages if problems are found.
Use the light path diagnostic LEDs on the BladeCenter HT unit and the
BladeCenter HT components to identify system errors quickly. See "Light path
diagnostic LEDs" on page 74.
Real Time Diagnostics tests the major components of the BladeCenter HT unit,
including the management modules, I/O modules, removable-media drives, and
the blade servers. 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/. See the
Problem Determination and Service Guide for more information.
The management module stores system events and can be accessed through
the management module user interface. See the User's Guide that comes with
the management module for more information.
The management module stores important hardware information that can be
accessed through the management module user interface. See the User's Guide
