Agree. I have a VAX3900

guess is that you have kind of 'minimal' system such
that all your boards are on the right half of the
backplane. Since no board is drawing power from the
leftside PSU it is unhappy. Solution is to add any
board for the left side PSU as I did. I used a M9060
load board.
I'd like to know if there is anything different about the BA213 backplanes
which came with the eariler? DECserver 500's. They have only a plug on
the backplane for the right power supply.
I wonder if this backplane would work on a lightly loaded VAX which makes
me wonder if there is something different about the board which allows
DCOK to work with only one H7868 power supply.
