correctly installed and compatible with the blade server and its components. If
the device or component is not compatible, remove it from the blade server,
reinstall the blade server in the BladeCenter unit, and then restart the blade
server.
The POST error codes indicate the detection of a problem. See the Problem
Determination and Service Guide for more information.
These tables list problem symptoms and actions to correct the problems. See the
Problem Determination and Service Guide for your blade server.
Use light path diagnostics LEDs on the system board to diagnose system errors.
If the system-error LED on the system LED panel on the front or rear of the
BladeCenter unit is lit, one or more error LEDs on the BladeCenter unit
components also might be lit. These LEDs help identify the cause of the
problem. Blade server error LEDs are described in the Problem Determination and
Service Guide for your blade server.

DSA 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. DSA can be plugged into an
existing IBM Director environment or installed without IBM Director present.
