Rack Cautions
Caution - Equipment Loading: Always load equipment into a rack from the bottom up so that
the rack does not become top-heavy and tip over. Deploy the rack's anti-tilt bar to prevent the
rack from tipping during equipment installation.
Caution - Elevated Operating Ambient Temperature: If the server is installed in a closed or
multi-unit rack assembly, the operating ambient temperature of the rack environment might be
greater than room ambient temperature. Therefore, install the equipment only in an environment
compatible with the maximum ambient temperature (Tma) specified for the server.
Caution - Reduced Air Flow: Install the equipment in a rack so that the amount of air flow is
adequate for the safe operation of the equipment.
Caution - Mechanical Loading: Mount the equipment in the rack so that the weight is
distributed evenly. A hazardous condition can exist with uneven mechanical loading.
Caution - Circuit Overloading: Do not overload the power supply circuits. Before connecting
the server to the supply circuit, review the equipment nameplate power ratings and consider the
effect that circuit overloading might have on overcurrent protection and supply wiring.
Caution - Reliable Grounding: Maintain reliable grounding of rackmounted equipment. Give
particular attention to supply connections other than direct connections to the branch circuit (for
example, use of power strips).
