I am trying to optimize my 4000 200 crate as to power
distribution in the main BA213 cabinet.  I vaguely recall
reading somewhere that each power supply only powers
certain slots in the backplane, plus some internal drives.
The machine is using 4 3.5" drives internally that I plan
on moving externally into storageworks shelves.  Thus,
the internal power supplies will only be powering up the
cpu/ram/scsi cards, and maybe a cxy08 card.  Is that
enough load on the internal power supplies, or should I
leave some drives in there, too?

Thanks
