Abstract
The present disclosure describes electrical circuit means for providing an automatic power restart for unattended electrical equipment, such as computer cabinets, after an AC power failure and subsequent power restoration. The restart function is performed without interfering with the normal cabinet power sequencing during attended operation or maintenance. The circuit which utilizes a latch-in type relay to "remember" the last manually selected power control setting has general utility in new installations, as well as being adaptable to existing cabinet power systems.
