Lifting the Chassis Safely
The chassis weighs 76 pounds when empty (no processor modules or power supplies installed) and 145 pounds when fully configured with two power supplies and all interface slots populated. Whenever you lift the chassis or any heavy object, follow these guidelines:
Warning Two people are required to lift the chassis. Grasp the chassis underneath the lower edge and lift with both hands. To prevent injury, keep your back straight and lift with your legs, not your back. To prevent damage to the chassis and components, never attempt to lift the chassis with the handles on the power supplies or on the interface processors, or by the plastic panels on the front of the chassis. These handles were not designed to support the weight of the chassis. (For translations of this safety warning, refer to the section “Chassis Lifting Warning” on page 39.)
