Abstract
Multi-module keying systems and methods include a chassis. A first module slot and a second module slot are located on the chassis. A keying device is movably coupled to the chassis and includes a first keying member that is located adjacent the first module slot and a second keying member that is located adjacent the second module slot. The keying device is configured to move in response to a first keyed module being positioned in the first module slot such that the first keyed module engages the first keying member. The movement of the keying device positions the second keying member adjacent the second module slot to restrict modules that may be positioned in the second module slot to second keyed modules. The systems and methods allow the second module slot to be keyed for second keyed modules based on the first keyed module positioned in the first module slot.
