Dear Sir,
I have Dell PowerEdge R720 Server with two power supply
P/N 06W2PW i download it's firmware upgrade and run it over Microsoft Windows Server 2012 R2
After some minutes the server restart and enter update utility to start update firmware
After some minutes the server shutdown immediately and start every minute to enter life cycle to start process again then shutdown again
Now the 2 PSU flicking yellow and server have no power
I have another R720 Server
