DL360G4p: Fault LED still amber after repaired

Hi
I have a DL360G4p system that had its front ventilation blocked resulting in CPU overheating. Lucky for me, the temperature returned to normal immediately as the processing load dropped. There is no Automatic Server Reboot. I ran the online insight diagnostic and there is no problem reported. But the fault LED is still amber. How should I clear this amber light? attached is the IML log below. It seems that the server is already "Repaired"

Re: DL360G4p: Fault LED still amber after repaired

When the die temperature on the processor reaches a predefined limit, the processor will automatically slow its core frequency by 50%. The slower speed requires less power and helps lower the processor die temperature.

While this feature allows the server to continue operating in an environment with an elevated temperature and is preferable to a forced shutdown, it is a situation that can be prevented with proper cooling both inside the server and in the data center.

The DL360 G4p Server has 7 system fans, 3 fans are for the I/O fan assemblies and 4 fans are for the processors.

Please check the for any Fan faiures physically. Possibly one of the fans has failed.
