The leveling feet are designed to align the rack in an upright,level position when the rack is situated on a slightly uneven floor surface.Before you install your systems in the rack, deploy and adjust the leveling feet.When you level your rack, follow these guidelines.WARNING: When you adjust the leveling feet, ensure that the casters on eachcorner of the rack do not rise more than 9.5 mm (3/8 inch) above the floor. If youexceed 9.5 mm of clearance between the floor and the casters as you adjust theleveling feet, slowly retract the leveling feet, and then move the rack to anotherlocation that requires minimal adjustments to the leveling feet.WARNING: Adjust the leveling feet until each leveling foot rests firmly on thefloor. Proper contact with the floor ensures that each leveling foot is supportingthe weight of the rack and prevents the rack from swaying in any direction. If theleveling feet are not all in firm contact with the floor, the rack can becomeunstable and tip over.WARNING: Do not attempt to move your rack with the leveling feet deployed.Always retract the leveling feet before moving the rack. Having the leveling feetdeployed when you move the rack may cause the rack to tip over.WARNING: Always level the rack and install the stabilizing feet before youinstall your systems. A fully loaded rack may tip over if your rack is resting on anuneven floor surface and the leveling and stabilizing feet are not supporting theweight of the rack.NOTE: If the rack is not leveled properly, you might not be able to install thestabilizer feet, which are necessary to prevent the rack from tipping over.
