General Server Precautions
•
Review the electrical and general safety precautions that came with the components you are adding to
your chassis.
•
Determine the placement of each component in the rack before you install the rails.
•
Install the heaviest server components on the bottom of the rack first, and then work up.
•
Use a regulating uninterruptible power supply (UPS) to protect the server from power surges, voltage
spikes and to keep your system operating in case of a power failure.
•
Allow the hot plug hard drives and power supply modules to cool before touching them.
•
Always keep the rack's front door and all panels and components on the servers closed when not servicing
to maintain proper cooling.
Rack Mounting Instructions
•
Ambient Operating Temperature — If installed in a closed or multi-unit rack assembly, the ambient
operating temperature of the rack environment may be greater than the ambient temperature of the room.
Therefore, consideration should be given to installing the equipment in an environment compatible with
the manufacturer’s maximum rated ambient temperature (Tmra).
•
Reduced Airflow — Equipment should be mounted into a rack so that the amount of airflow required for
safe operation is not compromised.
•
Mechanical Loading — Equipment should be mounted into a rack so that a hazardous condition does
not arise due to uneven mechanical loading.
•
Circuit Overloading — Consideration should be given to the connection of the equipment to the power
supply circuitry and the effect that any possible overloading of circuits might have on overcurrent protection
and power supply wiring. Appropriate consideration of equipment nameplate ratings should be used when
addressing this concern.
•
Reliable Ground — A reliable ground must be maintained always. To ensure this, the rack itself should be
grounded. Attention should be given to power supply connections other than the direct connections
to the branch circuit (i.e. the use of power strips, etc.).
