If the equipment contains any three-phase synchronous
motors, you have to
get the phases in the right sequence; if they are reversed, the motors run
backwards. ?That can affect blowers, and the spindle motors of disk drives.
I am not sure about these two controllers, but most larger IBM pieces
have phase rotation sensors, and will power check if hooked up wrong.
