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).
