Follow these steps to safely rackmount the Total Access 900 Series:
ADTRAN recommends 1U (1.75 inches) of separation above and below the
Total Access 900 Series unit. This spacing allows the unit to dissipate heat. The
design of the Total Access 900 Series uses the chassis to distribute heat
generated by the unit’s internal cards. This design allows the unit to operate
without a cooling fan, ensuring the overall reliability of the unit.
• If installed in a closed or multi-unit rack assembly, the operating ambient
temperature of the rack environment may be greater than room ambient
temperature. Therefore, consideration should be given to installing the
equipment in an environment compatible with the maximum ambient
temperature specified by the manufacturer.
• 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.
• Be careful not to compromise the stability of the equipment mounting rack when
installing this product.
• Consideration should be given to the connection of the equipment to the supply
circuit and the effect that overloading the circuit might have on overcurrent
protection and supply wiring. Appropriate consideration of equipment
nameplate ratings should be used when addressing this concern.
• Reliable grounding 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).
