• Install the heaviest enclosure components in the bottom of the rack first, and then work up.
• Use a regulating uninterruptible power supply (UPS) to protect the server from power surges
and voltage spikes and to keep your system operating in case of a power failure.
• Allow the hot-pluggable drives and power supply modules to cool before touching them.
Rack Mounting Considerations
Use the guidelines in the following subsections when rack mounting servers or JBOD expansion
units.
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 (
35º C or 95º F)
.
Reduced Airflow
Equipment should be mounted into a rack so that the amount of airflow required for safe operation
is not compromised. Always keep the rack’s front door and all panels and components on the
systems closed when not servicing to maintain proper cooling.
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 over-current protection and
power supply wiring. Appropriate consideration of equipment nameplate ratings should be used
when addressing this concern.
