ABSTRACT:
The present invention relates to a power sequence device which comprises an element which generates a sequencing code which is capable of being decoded by actuators included in the various equipment cabinets. The sequencing code is initiated by a sensing element which indicates the input power has reached a stable threshold whereupon the various cabinets comprising the data processing system are turned on in a desired order. Upon loss of power, the sensing element generates a warning signal indicating an impending power loss thereby enabling the equipment to perform an orderly halt.
