Chapter 6: Rack Installation
Rack Mounting Considerations
Ambient Operating Temperature
If installed in a closed or
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.).
To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety:
•This unit should be mounted at the bottom of the rack if it is the only unit in the rack.
•When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.
•If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack.
