General Server Precautions
ÌReview the electrical and general safety precautions that came
with the components you are adding to your appliance.
ÌDetermine the placement of each component in
the rack before you install the rails.
ÌInstall the heaviest server components on the bottom
of the rack first, and then work up.
ÌAllow the hot plug hard drives and power supply
modules to cool before touching them.
ÌAlways keep the rack‘s front door, all panels and server components
closed when not servicing to maintain proper cooling.
Rack Mounting Considerations
ÌAmbient operating temperature: If installed in a closed or multiunit rack
assembly, the ambient operating temperature of the rack environment
may be greater than the ambient temperature of the room. Therefore,
you should install the equipment in an environment compatible with
the manufacturer’s maximum rated ambient temperature.
ÌReduced airflow: Equipment should be mounted into a
rack with sufficient airflow to allow cooling.
ÌMechanical loading: Equipment should be mounted into a rack so that a
hazardous condition does not arise due to uneven mechanical loading.
ÌCircuit 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.
ÌReliable ground: Reliable grounding must be maintained at all times.
To ensure this, the rack itself should be grounded. Particular 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.).
