2.4 Safety Instructions for Rack Mount Installations
The following safety precautions shall be adhered to when mounting appliances into a rack:
• Elevated Operating Ambient—If installing an appliance in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack environment may be greater than
the room ambient. Consideration should be given to installing the appliance in an
environment compatible with the maximum ambient temperature (Tma) specified by the
manufacturer.
• Reduced Air Flow—Installation of the appliance 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 appliance in the rack should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
• Circuit Overloading—Consideration should be given when connecting appliances to the
supply circuit so that protection is provided to the appliances and supply wiring if any circuit
overloads occur. Appropriate consideration of the equipment nameplate ratings should be
used when addressing this concern.
• Reliable Earthing—Reliable earthing of rack-mounted appliances 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).
CAUTION
Ensure that the electrical circuit through which the ADSP appliance is
powered can safely accommodate a 250 Watt power supply for the
Model 125x/ 365x appliance or a 500 Watt power supply for the
Model 4250 appliance.
CAUTION AirDefense highly recommends that you connect the ADSP appliance
to a UPS (uninterruptible power supply). There are instances in which
the system software could become corrupt and un-recoverable in the
event of power loss, for example, during a system upgrade, database
backup, or database restore operation.
CAUTION There is a risk of explosion if battery is replaced by an incorrect type.
Dispose of used batteries according to the instructions.
