Abstract

In systems that have multiple components that use distinct backup power sources, when the system transitions to backup power there will likely be differences in the state of the backup power sources. In an implementation that only provides a single status system status indicator, it is important that the indicator provide status for the most limiting condition else a portion of the system may fail without providing adequate warning to the user.
