To prevent bodily injury when lifting or moving the chassis or other components, follow
these guidelines.
Considerations Before You Begin
The weight of the chassis, as delivered, is approximately 80 lb (36.30 kg), which includes
the Power Entry Modules (PEMs) and FAN modules. Before lifting, you might want to
remove the PEMs and FAN modules to reduce the weight by approximately 10 lb (4.6
kg). See
“BTI7814 Field-Replaceable Units (FRUs)” on page 179 for instructions on removing
and reinstalling these modules.
Always use best practices to lift and move the chassis. We recommend the following:
•
A minimum of two people.
•
Four people to provide proper balance and safety—two at the front and two at the
back.
• You should have a dolly on hand to move the chassis, or a mechanical lift, particularly,
if you are mounting the chassis at the top of the rack. Because of the weight of the
chassis, the mechanical lift provides safety and ease for lifting the chassis to a high
rack position.
CAUTION: To ensure safety, follow these guidelines:
• Ensure that your footing is solid.
•
Do not move suddenly or twist your body when lifting the chassis.
