One more thing you might want to watch out for with excessive +5 voltage drop
on an 8/E is the 5V fuse. I have mine almost full of cards and the fuse
holder melted. I have a maintenance handbook (which I got after the failure)
which said that this was a known problem. I measured the current draw and
found it was slightly above the power supply rating so added another supply
to power half the backplane.
