NI HDD-8266 Installation Guide
Rack Mount Safety Information
Caution
Due to the device weight, two people should work together to mount the
device in a rack.
Caution
Install the unit as low as possible in the rack to maintain a lower center of
gravity and prevent the rack from tipping when moved.
Follow these safety guidelines when installing the device in a rack:
•
Elevated Operating Ambient
—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, you should install the equipment in an environment compatible
with the maximum ambient temperature (T
ma
) of 40 °C.
•
Reduced Air Flow
—When installing the equipment in a rack or cabinet, do not
compromise the amount of airflow required for safe operation of the equipment.
•
Mechanical Loading
—When mounting the equipment in the rack or cabinet, avoid uneven
mechanical loading that could create a hazardous condition.
•
Circuit Overloading
—When connecting the equipment to the supply circuit, avoid
overloading the circuits. Refer to equipment nameplate ratings to avoid damaging over
current protection and supply wiring.
•
Reliable Earthing
—Maintain reliable earthing of rack-mounted equipment, especially
when using supply connections other than direct connections to the branch circuit (for
example, power strips).
•
Redundant Power Supplies
—Where redundant power supplies are provided with the
equipment, connect each power supply to a separate circuit to optimize the equipment
redundancy.
•
Servicing
—Prior to servicing the equipment, disconnect all power supplies.
