Abstract

Disclosed is a device which improves the way power is applied to components in digital systems, including computers and especially servers. The invention will protect the components from receiving power when they might be damaged due to wrong voltage or improper attachment. The invention will also guarantee that proper system parameters necessary for reliable operation are met before power is supplied. The invention will distinguish between part of the system capable of operating reliably and without damage and another part that cannot. It will allow the reliable part to function while protecting from damage other components and preventing errors from occurring (when more than one instantiation of this invention occurs within the system). Relevant Prior Art Note: The voltage produced by A and B are always enabled by the pullup resistor. Figure 1 First example of prior art
