Abstract
An apparatus and method for enabling hot swapped circuit boards to receive multiple power voltages from a backplane and supply the multiple power voltages to devices on the circuit board in a predictable sequence. An apparatus according to the invention would include a circuit board having an electrical connector, a sequencing circuit, and an element. The electrical connector of the circuit board receives the multiple power voltages from another circuit board, such as a backplane or motherboard. The sequencing circuit receives the multiple power voltages from the electrical connector. When a part of the sequencing circuit receives a signal indicating that the sequencing circuit has received a first power voltage, the sequencing circuit provides a second power voltage to the element electrically coupled to the sequencing circuit.
