The racks should all come up standalone. My understanding is that when you
connect them together and power on the first node it'll designate itself
the Master and then go and locate all the other systems in the cluster,
bringing them up individually and working out what their hinv consists of
and the like, as well as shortest-distance between nodes to generate the
node map, to generate the "system image" it's going to work with. I
However, any individual rack, or pair, or triplet, etc, should work
without too much fuss on their own. Right now I've never powered any of
them on - I used the 220v feed to my A/C for a drop, but never actually
got around to bringing any of the racks up. That, however, should change,
with the new building.
