Hi, 

My R720 Server has a faulty iDrac error, so that I can't boot it anymore.

I tried removing power and cables, press Start 10 seconds, reconnect and try restart (same error again).

Tried NSRAM reset, does the same.

It seems that I need to change the MotherBoard.

But there are lots of different referencies.

Do I need to use exactly the same ref or not ?

Server SN : FK1T842 (no more support)

My ref :  PTWDY Rev A03

CN-0JP31P-77921-4CO-00J5-A14

DP/N : DJP31P

 Thank you for your help.
