Diagnostic tools overview The following tools are available to help you diagnose and solve hardware-related problems: v Troubleshooting tables These tables list problem symptoms and steps to correct the problems. See "Troubleshooting tables" for more information. v Diagnostic programs and error messages The built-in self-test (BIST) program checks the BladeCenter unit during startup and generates error messages if problems are found. v Light path diagnostic LEDs Use the light path diagnostic LEDs on the BladeCenter unit and the BladeCenter components to identify system errors quickly. See "Light path diagnostic LEDs" on page 44. Troubleshooting tables Use the troubleshooting tables to find solutions to problems that have identifiable symptoms. Note: The symptoms for monitor, keyboard, and mouse apply only to the devices that are connected to the management module; they do not apply to the remote console. See the Problem Determination and Service Guide for more detailed information about testing the BladeCenter unit. If you have run the diagnostic test programs or if running the tests does not reveal the cause of problem, call for service. Attention: If diagnostic error messages appear that are not listed in the Problem Determination and Service Guide, make sure that the latest level of firmware code is installed in your BladeCenter unit.

v
Diagnostic programs and error messages
The built-in self-test (BIST) program checks the BladeCenter unit during startup
and generates error messages if problems are found.
v
Light path diagnostic LEDs
Use the light path diagnostic LEDs on the BladeCenter unit and the BladeCenter
components to identify system errors quickly. See “Light path diagnostic LEDs”
on page 44.
Troubleshooting tables
Use the troubleshooting tables to find solutions to problems that have identifiable
symptoms.
Note:
The symptoms for monitor, keyboard, and mouse apply only to the devices
that are connected to the management module; they do not apply to the

if running the tests does not reveal the cause of problem, call for service.
Attention:
If diagnostic error messages appear that are not listed in the
Problem
Determination and Service Guide
, make sure that the latest level of firmware code
is installed in your BladeCenter unit.
