Hello
Have problems updating the firmware for the (AC) PSU for the R720, tried doing it from the lifecycle controller and by downloading and running the windows package from Win2008 R2.
After installing in both cases, the server powered down, but didn't wake up as advertisied (I waited overnight). Out of options I pressed the power button, and the firmware didn't upgrade.
I also tried plug in only 1 PSU, with the same result
Any help is appreciated, thanks for reading
Details about my config:
Old firmware version of PSU: 07.25.7D
Target firmware viersion: 07.25.7E
