another person to assist you so that one person can support the chassis while the other installs the
fasteners.
Ensure that heavier equipment is installed near the bottom of the rack to maintain a low

center of gravity. Otherwise, because the two front posts bear the entire weight of the chassis, the
rack could become top-heavy and tip over if it is not stabilized with heavier equipment at the bottom
or anchored to the floor.

the brakes are engaged or that the rack is otherwise stabilized.
Never attempt to lift or tilt the chassis with the handles on the interface processor carriers
