3-2 Rack-Mount Server Installation
WARNING: To reduce the risk of personal injury or damage to the equipment, at least two people are needed to safely unload the rack from the pallet. An empty 42U rack weighs 253 LB (115 kg), is over seven ft (2.1m) tall, and may become unstable when being moved on its casters. Do not stand in front of the rack as it rolls down the ramp from the pallet, but handle it from the sides.
WARNING: Because the rack allows you to stack computer components on a vertical rather than a horizontal plane, you must take precautions to provide for rack stability and safety. It is important that you follow these basic instructions to protect both personnel and property, and that you heed all cautions and warnings throughout the installation instructions.
WARNING: Always load the heaviest item first and always load the rack from the bottom up. This will make the rack "bottom- heavy" and help prevent the rack from becoming unstable. See "Rules for the Rack Builder" on the Rack Builder diskette for the rules that govern the vertical placement of
WARNING: A rack may become unstable if more than one component is extended for any reason. To reduce the risk of personal injury, always ensure that the rack is adequately stabilized before extending a component outside the rack, and extend only one component at a time.
WARNING: Before beginning to work on the rack, be sure that the leveling jacks are extended to the floor, that the full weight of the rack rests on the level floor, and that either stabilizers are installed or that multiple racks are coupled together for stability.
CAUTION: Do not place anything on power cords or cables. Arrange them so that no one may accidentally step or trip over them. Do not pull on a cord or cable. When unplugging from the electrical outlet, grasp the cord by the plug.
WARNING: To avoid the risk of personal injury or damage to the equipment, a minimum of two people MUST lift the server into the rack. The server weighs about 50 pounds (22.6 kilograms). If the unit is to be loaded above chest level, a third person must assist in aligning the rails while the other two support the unit.
