Claim:
A system for preventing disconnection of a module from a module connector prior to initiating a shutdown routine, the system comprising: on a module comprising a hardware component adapted for insertion in a slot in a shelf of a rack-based computing system: (a) a switch having a first state for allowing operation of the module and a second state for initiating a shutdown routine for controlling shutdown of the module; (b) at least one retention device for preventing disconnection of the module from a module connector for electrically connecting the module to the rack-based computing system; and (c) a covering member being movable between first and second positions with regard to the retention device and the switch; wherein, 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 wherein movement of the covering member from the first position to the second position transitions the switch to the second state.
