Service processor problems

Symptom
The service processor reports
a general monitor failure.

Light path diagnostics

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 I/O board and
processor board also might be lit. These LEDs help identify the cause of the
problem.

Diagnosing problems using the light path diagnostics

To locate the component that caused the error, locate the lit error LED on that
component.
