Mounting the Chassis
General Mounting Recommendations
Elevated Operating Ambient Temperature. If installed in a closed or multi-rack assembly, the operating
ambient temperature of the rack environment may be greater than the room's ambient temperature.
Therefore, consideration should be given to the maximum rated ambient temperature (Tmra) specified on
page 4-3.
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. Refer to
page 4-6 for more information.
Mechanical Loading. Mounting of the equipment in the rack should be such that a hazardous condition is
not achieved due to uneven loading.
Circuit Overloading. Consideration should be give to the connection of the equipment to the supply
circuit and the effect that overloading of circuits could have on overcurrent protection and supply wiring.
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 (e.g., use of
power strips).
Airflow Recommendations
To ensure proper airflow, the OS-BPS should be placed in a well-ventilated area with minimum
recommended clearance at front, back and sides of the chassis. (Clearance is not required at the top and
bottom of the chassis.) Restricted airflow can cause the chassis to overheat, which can lead to system
failure. Refer to the following important guidelines regarding airflow:
