Board status NOK.
Possible causes are:
● There is no power delivered on the +12 V rail of the PCI Express
connector slot
● The FPGA start-up procedure is not completed. The normal completion
time is around 100 milliseconds.
● At least one power converter of the main power distribution network is
unable to operate properly. This might be caused by excessive
temperature due to inadequate board cooling, accidental short-circuits
having blown one (or more) protection fuses, inappropriate supply
voltages, etc.
