Under normal conditions, an active/standby changeover will only occur if the new active module is
fault-free. Under some circumstances, it is desirable to be able to force a changeover to a known
faulted module. This can be accomplished by opening the Module Removal switches on the currently
active module and pressing the push-button reset on the TMR Processor. This will force the
changeover to proceed even if the new active module is not fault free.
