Light path diagnostics
You can use the light path diagnostics built into the server to quickly identify the type
of system error that occurred. Your server is designed so that LEDs remain
illuminated when the server shuts down, as long as the power supplies are operating
properly. This feature helps you to isolate the problem if an error causes the server to
shut down.
If the system error LED (on the information LED panel) is not lit and no diagnostics
panel LEDs are lit, it means that the light path diagnostics have not detected a system
error.
If the system error LED (on the information LED panel) is lit, it means that a system
error was detected. Check to see which of the LEDs on the diagnostics panel inside
the server are lit and refer to the following table:
