ABSTRACT:
Methods and systems are described for preventing disconnection of a module from a module connector prior to initiating a shutdown routine and for preventing operation of the module unless a retention device is engaged. The system includes a switch having a first state for allowing operation of a module and a second state for initiating shutdown and/or preventing operation of the module. At least one retention device prevents disconnection of the module from the module connector. A covering member is movable between first and second positions, but is prevented from moving to the first position when the retention device in not engaged. In the first position, the covering member prevents access to the retention device and the switch is in the first state and in the second position the covering member allows access to the retention device and transitions the switch to the second state.
