| 1. A method of keying implementation for swapping paired devices, comprising:
providing a controller module including a first keying member;
providing a power supply unit including a second keying member;
fully inserting said controller module and said power supply unit, next to each other, into receiving slots of a chassis so
that said power supply unit may supply power to said controller module when said first keying member matches said second keying
member; and
preventing said controller module and said power supply unit from being fully inserted, next to each other, into said receiving
slots when said first keying member and said second keying member interfere with each other,
wherein when said first keying member matches said second keying member, a power requirement of said controller module substantially
matches a power production capability of said power supply unit.
