Chapter 6: Rack Installation

Rack Mounting Considerations

Ambient Operating Temperature

If installed in a closed or multi-unit rack assembly, the ambient operating tempera-
ture 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 tempera-
ture (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  at  all  times. To  ensure  this,  the  rack  itself 
should be grounded. Particular attention should be given to power supply connec-
tions other than the direct connections to the branch circuit (i.e. the use of power 
strips, etc.).
