Rack Mount Safety Consideration
•
Elevated Ambient Temperature
If installed in a closed or multi-unit rack assembly, the operating ambient
temperature of the rack environment may be greater than room
ambient. Use care not to exceed the rated maximum ambient
temperature of the unit.
•
Reduced Air Flow
Installation of the equipment in a rack should be such that the amount of
airflow 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. Pay
particular attention to supply connections other than direct connections
to the branch circuit (e.g. use of power strips)."
