Diagnostic panel error LEDs

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.

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.

Notes:

1.To locate the LEDs on the system board see “System board component locations” on page 42

2.Check the System Error Log for additional information before replacing a FRU.

3.It may be necessary to view the System Error Log from a remote connection, such as MOST.

4.The memory card DIMM error LEDs and processor error LEDs turn off when the system is powered down.

Note: The System Error LED will also be on.
