Stabilizing the System
Observe the following general precautions to stabilize the system:
•Install any stabilizers that came with your equipment rack before mounting or servicing the system in the rack.
•Load the rack from the bottom to the top, with the heaviest system at the bottom.
•Do not stack the system on top of any other equipment. If the system falls, it can cause severe bodily injury and damage the equipment.
•If you are using an equipment shelf, ensure that the shelf is constructed to support the weight and dimensions of the chassis.
•If you are using a telco rack, ensure that the weight of the chassis does not make the rack unstable. Secure the telco rack with ceiling brackets if the rack is populated with heavy equipment.
•Bolt the rack to the floor for stability.
Lifting the System
Observe the following general precautions when lifting the system:
•Disconnect all power and external cables before lifting the system.
•Ensure that your footing is solid and the weight of the system is evenly distributed between your feet.
•Lift the system slowly, keeping your back straight. Lift with your legs, not with your back. Bend at the knees, not at the waist.
•Depending on the weight of the system, more than one person might be required to lift it.
