Make sure you have fans connected to the correct fan headers. You should have CPU fans and Chassis Fan 1, 3 and 5 connected. See Quick start guide for details. Run SEL Viewer and see if any errors cause the full speed fans.
The serial numbers and product codes are printed on the label of the board/chassis. But you can answer No when promted about serial number&product code update, if you don't want to log them. It doesn't affect fan speed control.
Thank You very much for help.
I'll check fans connections at Monday. But before upgrade it works normally and I think all is connected correctly there, I tried to upgrade FRU SDR two times without success.
On some stage I selected SC5650WS as chassis.
But maybe better to select "Other" and manually denote Fans are connected/disconnected?
What do you think about it?
I'll try a lot of at Monday and I'll inform about my results.
With best regards, Alexandr.
