v 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/. See the Problem Determination and Service Guide for more information. Note: If you are unable to find the system error logs in the blade-server firmware code, view the system event log in the BladeCenter management module. v Light path diagnostics Use light path diagnostics LEDs on the blade server system board and MPE to identify 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 and MPE error LEDs are described in the Problem Determination and Service Guide for your blade server.
