Cisco Systems Cisco 7000, Cisco 7507 installation instructions Lifting Safely

Page 9

Prerequisites

Ensure that your footing is solid and balance the weight of the object between your feet.

Lift the object 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 lower back muscles. (See Figure 5.)

Grasp the underside of the chassis exterior with both hands.

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 32.)

H2336

Caution To avoid damage to power supplies and interface processors, never attempt to lift the chassis using the handles on the power supplies or the interface processors. These handles were not designed to support the weight of the chassis.

Note The following warning is for units equipped with DC-input power supplies.

Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position. (For translations of this safety warning, refer to the section “DC Power Disconnection Warning” on page 33.)

Remove all power supplies before lifting the chassis. Each supply weighs 20 pounds (9.1 kg).

Leave the Route Processor (RP), Switch Processor (SP) (or Silicon Switch Processor [SSP]), and all interface processors installed; each weighs less than five pounds (2.3 kg).

Always disconnect all external cables before lifting or moving the chassis.
