Safety notes
Rack Installation
CAUTION
Elevated Operating Ambient
If installed in a closed or multi-unit rack assembly, the operating ambient
temperature of the rack environment may be greater than room ambient.
Therefore, consideration should be given to installing the equipment in an
environment compatible with the maximum ambient temperature (Tma) specified
by the manufacturer.
Reduced Air Flow
Installation of the equipment in a rack should be such that the amount of air flow
required for safe operation of the equipment is not compromised.
Mechanical Loading
Mounting of the equipment in the rack should be such that a hazardous condition
is not achieved due to uneven mechanical loading.
Circuit Overloading
Consideration should be given to the connection of the equipment to the supply
circuit and the effect that overloading of the circuits might have on overcurrent
protection and supply wiring. Appropriate consideration of equipment nameplate
ratings should be used when addressing this concern.
Reliable Earthing
Reliable earthing of rack-mounted equipment should be maintained. Particular
attention should be given to supply connections other than direct connections to
the branch circuit (e.g., use of power strips).
WARNING
Disconnect the power plug before cleaning the server.
Be to power off the server and disconnect the power plug from a power outlet
before cleaning or installing/removing internal optional devices. Touching any
internal device of the server with its power cord connected to a power source
may cause an electric shock even of the server is off-powered.
Occasionally disconnect the power plug from the outlet and clean the plug with a
dry cloth. Heat will be generated if condensation is formed on a dusty plug, which
may cause a fire.
CAUTION
High temperature
Components including internal hard disk drives in the server are extremely hot just
after the server is turned off. Allow the surface to cool before installing/removing.
Secure cables or cards in place
Be sure to secure the power cord, interface cables, and cards in place.
Incomplete installation causes a loose connection, resulting in smoke or fire.
