status code : 0168

Hi Everyone,

I have a <  ML310e Gen8 v2 server and it recently decided fail to POST after I tried to reboot the server.  

It turns on for ~5 seconds, where I can see it's still only at 20% of the POST, doing CPU initialization.  The Code at the bottom right of the screen reports 0168.

and Hear the sound of a continuous pep And then a black screen

 battery is disconnected No Change 
RAM changed  was No changed
I unplugged the SPS-CABLE, TEMP SENSOR and no response
Thank you
