I am not sure about equipment of that date, much less
IBM equipment of that
date, but I'd guess that undervoltage is less likely to be harmful than
overvoltage. ?(Some switch mode power supplies may draw too much current if
the voltage is low, and kill themselves that way.) ?So err on the side of
lower voltage.
Basically, just about any configuration of wires that are sticking out
of the wall can be hooked up to these controllers, and if they do not
like what they are getting, they will not power up ("power check" in
IBM talk). Just about everything is checked before any of the brains
get any power.
Not that one should be careless here, but IBM mainframe equipment does
offer a bit of comfort when it comes to the smoke test.
