Electrical and Mechanical Safety Information Products with Casters Products provided with casters should be moved with care. Quick stops, excessive force, and uneven surfaces may cause the product to overturn. Floor Standing Products Be sure the bottom stabilizers on the equipment are installed and fully extended. Ensure that the equipment is properly stabilized and supported before installing options and cards. Rack-Mountable Products Because the rack allows you to stack computer components vertically, you must take precautions to provide for rack stability and safety: ❒ Do not move large racks by yourself. Due to the height and weight of the rack, HP recommends a minimum of two people to accomplish this task. ❒ Before working on the rack, be sure the leveling jacks (feet) extend to the floor and that the full weight of the rack rests on the floor. Also install stabilizing feet on a single rack or join multiple racks together before starting work. ❒ Always load the rack from the bottom up, and load the heaviest item in the rack first. This makes the rack bottom-heavy and helps prevent the rack from becoming unstable. ❒ Ensure that the rack is level and stable before extending a component from the rack. ❒ Extend only one component at a time. The rack may become unstable if more than one component is extended. ❒ Use caution when pressing the component rail release latches and sliding a component into the rack. The slide rails could pinch your fingers. ❒ Do not extend the components from the rack too quickly as the moving weight may damage the supporting rails. ❒ Do not overload the AC supply branch circuit that provides power to the rack. The total rack load should not exceed 80% of the branch circuit rating. 7-8 Safety & Comfort Guide
