Abstract
A power-up sequencing apparatus for successively energizing a plurality of associated subsystems in a host system, including a series of interconnected sequencing circuits, each sequencing circuit interconnected with a subsystem and including first switching means responsive to an initial system power-up for disabling its associated subsystem; second switching means responsive to an initial system power-up for suppressing the start command to the next sequencing circuit in the series; and third switching means responsive to a start command for operating the first switching means to enable its associated subsystem and for operating the second switching means to introduce a start command to the next sequencing circuit in the series.
