Equipment Environmental and Safety Guidelines
When you install the Avid Nitris in a rack, you must take the following precautions:
•Elevated Operating Ambient Temperature — When the Avid Nitris is installed in a
closed or multiunit rack assembly, the operating ambient temperature of the rack
environment might be greater than the room ambient temperature. Therefore, consider
installing the equipment compatible with the manufacturer’s maximum ambient
temperature of 104°F (40°C).
•Reduced Airflow — Do not compromise the amount of airflow required for safe
operation of the equipment.
•Mechanical Loading — Avoid a hazardous condition due to an uneven mechanical
loading.
•Circuit Overloading — Consider connecting the equipment to the supply circuit and
the effect that overloading of circuits might have on overcurrent protection and supply
wiring. Use appropriate equipment nameplate ratings.
•Reliable Earthing — Maintain reliable earthing of rack-mount equipment. Give
particular attention to supply connections other than direct connections to the branch
circuit (for example, the use of power strips).
Installing the Avid Nitris in a Rack
The Avid Nitris is designed for 19-inch (483-mm) rack enclosures and requires three EIA
rack units (3U), or 5 ¼ inches (133.4 mm) of rack space. The Avid Nitris is shipped with
rack-nut clips for those rack enclosures that do not have threaded holes. Rack-nut clips are
clipped in the holes of the rack that are used to secure the rack components in place.
wTo ensure the stability of the rack enclosure, start from the bottom when you install the
rack components in the rack enclosure.
Positioning the Avid Nitris in the Rack
The following procedure helps you decide where to install the Avid Nitris in the rack. If your
rack enclosure does not have threaded holes, install the rack-nut clips included with the
Avid Nitris where the Avid Nitris front panel secures to the rack enclosure. If your rack
enclosure has threaded holes, do not attach the rack-nut clips.
