General Precautions for Rack-Mountable Products

Observe the following precautions for rack stability and safety. Also refer to the rack
installation documentation accompanying the system and the rack for specific caution
statements and procedures.
Systems are considered to be components in a rack. Thus, "component" refers to any system
as well as to various peripherals or supporting hardware.
CAUTION: Installing systems in a rack without the front and side
stabilizers installed could cause the rack to tip over, potentially resulting in
bodily injury under certain circumstances. Therefore, always install the
stabilizers before installing components in the rack.
After installing system/components in a rack, never pull more than one
component out of the rack on its slide assemblies at one time. The weight
of more than one extended component could cause the rack to tip over
and may result in serious injury.
• Before working on the rack, make sure that the stabilizers are secured to the rack,
extended to the floor, and that the full weight of the rack rests on the floor. Install front
and side stabilizers on a single rack or front stabilizers for joined multiple racks before
working on the rack.
• Always load the rack from the bottom up, and load the heaviest item in the rack first.
• Make sure that the rack is level and stable before extending a component from the
rack.
• Use caution when pressing the component rail release latches and sliding a component
into or out of a rack; the slide rails can pinch your fingers.
• After a component is inserted into the rack, carefully extend the rail into a locking
position, and then slide the component into the rack.
• Do not overload the AC supply branch circuit that provides power to the rack. The
total rack load should not exceed 80 percent of the branch circuit rating.
• Ensure that proper airflow is provided to components in the rack.
• Do not step on or stand on any component when servicing other components in a rack.
