Chassis-Lifting Guidelines
The chassis is not intended to be moved frequently. Before you install the system, ensure that your site
is properly prepared so that you can avoid having to move the chassis later to accommodate power
sources and network connections.
Two or more people are required to lift the chassis. Each time you lift the chassis or any heavy object,
follow these guidelines:
•Never attempt to lift the chassis by yourself. Because of the size and weight of the chassis, use at
least two people to safely lift and move it without causing injury to yourself or damaging the
equipment.
•Ensure that your footing is solid, and balance the weight of the chassis between your feet.
•Lift the chassis slowly; never move suddenly or twist your body as you lift.
•Keep your back straight and lift with your legs, not your back. If you must bend down to lift the
chassis, bend at the knees, not at the waist, to reduce the strain on your back muscles.
•Do not remove installed components from the chassis.
•Always disconnect all external cables before lifting or moving the chassis.
Warning
To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the
handles on modules (such as power supplies, fans, or cards); these types of handles are not designed
to support the weight of the unit. Lift the unit only by using handles that are an integral part of the
chassis, or by grasping the chassis underneath its lower edge.
Statement 163
Perform the following to lift a chassis:
Step1 Each person should stand on either side of the chassis and place one hand under the air intake at the
bottom front of the chassis.
Step2 With the other hand, grasp the top rear of the chassis under the air exhaust, and carefully lift the chassis.
