System and method for starting up plural electronic devices in an orderly manner

摘要

A system for starting up plural electronic devices in an orderly manner includes a power source and a plurality of backboards electrically connected thereto. Each backboard includes a controller for outputting a low voltage signal; a plurality of jumpers electrically connected to the controller and to ground in parallel; a switch electrically connected to the controller for controlling electrical current; and an electronic device electrically connected to the switch. The switch on each backboard is electrically connected to the power source. The controller on each backboard configures a time delay of the low voltage signal to be output, according to a combination of the states of the jumpers on the backboard. Each jumper on each backboard can be in either a disconnected state or a connected state. A related method for starting up plural electronic devices in an orderly manner is also disclosed.
