Control Panel System Error LED



Control Panel System Error LED

The system error LED is turned on 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 replacing the problem.


Note:

  1.  To locate the LEDs on the processor board see 'Processor Board Component Locations'
  2.  To locate the LEDs on the system board see 'System Board Component Locations'.
  3.  Check the system error log for additional  information before replacing a FRU.
