Observe the following precautions for rack stability and safety. Also refer to the
rack installation documentation accompanying the rack for specific warning and
caution statements and procedures.

peripherals or supporting hardware.
• Do not move large racks by yourself. Due to the height and weight of the rack,
a minimum of two people are needed to accomplish this task.
• Ensure that the rack is level and stable before extending a component from
the rack.
• Do not overload the AC supply branch circuit that provides power to the rack.
The total rack load should not exceed 80% of the branch circuit rating.
• Ensure that proper airflow is provided to components in the rack.
• Do not step or stand on any system or component when servicing other
systems and components in a rack.
• This unit should be mounted at the bottom of the rack if it is the only unit in
the rack.
• When mounting this unit in a partially filled rack, load the rack from the
bottom to the top with the heaviest component at the bottom of the rack.
• If the rack is provided with stabilizing devices, install the stabilizers before
mounting or servicing the unit in the rack.
