A method and apparatus for an electronic equipment rack that provides mobility through directional self-propulsion and multi-axis suspension. The electronic equipment rack further provides self-powered operation and environmental control with wireless access, while protecting against unauthorized access, electromagnetic interference (EMI), and dust contamination. An alternate embodiment provides a non-mobile electronic equipment rack with multi-axis suspension, while optionally providing wireless access and protection against unauthorized access and the environment.
