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, Compaq 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 compo- nent rail release latches and sliding a component into the rack.The slide rails could pinch your fingers.

Do not overload theAC supply branch circuit that provides power to the rack. The total rack load should not exceed 80% of the branch circuit rating.
