A system and method for detecting blank modules includes an information handling system including at least one computing component, a modular chassis, a management module, and one or more sensors. The modular chassis includes one or more slots where each slot is operable to receive either the computing module or a blank module. The computing module interfaces with the management module whereby the management module is operable to detect the presence of one or more of the computing modules in one or more of the slots. The sensors are associated with each of the slots and detect if one or more of the blank modules are installed in one or more of the slots. In addition, the sensors provide an indication to a user when one or more of the slots are empty and do contain neither a computing module or a blank module.
