Information panel system error LED
The system error LED is turned on when an error is detected. If the system error
LED is on, remove the cover and check the diagnostic panel LEDs. The following is
a complete list of diagnostic panel LEDs followed by the FRU/Action for correcting
the problem. The following chart is valid only when the system error LED is on.
Note: If a diagnostic panel LED is on and the information LED panel system error
LED is off, there is probably an LED problem. Run LED diagnostics.
