Important safety information
WARNING: To reduce the risk of personal injury or damage to the equipment, be sure that:
• The rear leveling feet are extended to the floor.
• The full weight of the rack rests on the rear leveling feet and front stabilizer feet.
WARNING: To reduce the risk of personal injury or damage to the rack and equipment, the
racks must be positioned and secured together according to these instructions. Failure to do
so could result in an unstable installation.
WARNING: Components can be very heavy. To reduce the risk of personal injury or damage
to the equipment:
• Remove all pluggable power supplies and modules to reduce the weight of the product
before lifting it.
• Observe local occupational health and safety requirements and guidelines for manual
material handling.
• Get help to lift and stabilize the product during installation or removal, especially when the
product is not fastened to the rails. When the component weighs more than 22.5 kg (50
lb), at least two people must lift the component into the rack together. If the component is
loaded into the rack above chest level, a third person must assist in aligning the rails while
the other two support the component.
• Use caution when installing the component in or removing the component from the rack; it
is unstable when not fastened to the rails.
Additional rack considerations
• Power—If a UPS is installed, do not exceed the output rating. Be sure to review the installation
instructions provided with each component for important cautions and warnings.
• PDUs—Before installing other components, install the PDUs.
• Height—The height of the rack and of rack-mountable components is measured in U increments,
where U = 4.5 cm (1.75 in). When you are configuring your rack installation, remember that the
total U measurement of the components you want to install cannot exceed the stated U height of the
rack.
