Information Panel System Error LED

  Information 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.

  -Important- 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.

Notes:

•  To locate the LEDs on the processor board see Processor board component locations.
•  Check the System Error Log for additional information before replacing a FRU.
•  The memory board DIMM error LEDs, processor error LEDs,  and VRM error LEDs turn off when the system is powered down.
