Greetings!

Marwan,

As you mentioned you replaced with a known working power supply for DS15 and the issue still persists, I would suggest you to look in the below options now. 

Note: The DS15 system operates in an ambient temperature range of 10º degree C – 40º degree C. An internal sensor monitors the system temperature and shut down the system if maximum limits are exceeded...

Perform the following if the system shuts down unexpectedly:

• Ensure that the side cover (pedestal) or top cover (rack) are properly secured.
• Verify that the ambient temperature does not exceed the specified limits.
• Make sure there are no obstructions to the airflow at the front or rear of the system.
• Check to see that the cables inside the system are properly dressed. A dangling cable can impede airflow to the system.

Then please use show power command  which can help you determine if environmental problems necessitate the replacement of a power supply, system fan or fans, or the motherboard.

Regards,
