PowerEdge R730 failed to power ON

Hi All,

I do have one Dell PowerEdge R730 server where fails to boot.

I removed the HW components to post configuration:

• CPU 1
• 1 DIMM in Slot A1
• 1 Power Supply in Slot 1
• Control Panel (Which component that means?)
• Riser 1

Sadly still not boot up to Bios, did I missed something?

On the Mainboard the DS_LED0 stay after power cable has been plugged to PSU01. (Refer to enclosed screenshot)

Would it help to try a NVRAM_CLR?
