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.
Safety Instructions (continued)
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.
NOTE:
safety grounds. All electrical wiring must comply with applicable local or national
codes and practices.
CAUTION: Never defeat the ground conductor or operate the equipment in the
absence of a suitably installed ground conductor. Contact the appropriate electrical
inspection authority or an electrician if you are uncertain that suitable grounding is
available.
A qualified electrician must perform all connections to DC power and to
