OUNTING THE
OA-740
The OA-740 is mounted on a standard 19-inch equipment rack. To easily access
the electrical cables while the system is installed in a rack, ensure that you have
easy access to the front and rear of the system, and that there is about 20-inch
clearance at the front and rear of the rack.
You can also mount the OA-740 on an equipment shelf provided that the rack
dimensions allow you to secure the system to the shelf. However, Alcatel-Lucent
recommends rack-mounting the OA-740.
To rack-mount the OA-740, consider the following guidelines:
• Maximum recommended operating temperature
The maximum recommended operating temperature for the OA-740, indoor is
45°C. Determine a suitable operating environment based on this
recommendation.
• Elevated operating ambient temperature
If the unit is installed in a closed or multi-unit rack assembly, the operating
temperature of the rack environment may be greater than the ambient
temperature of the room. Keep this in mind when installing the OA-740.
• Reduced Airflow
Install the OA-740 shelf in the rack so that the amount of airflow required for safe
operation of the equipment in not compromised.
• Mechanical Loading
Mount the OA-740 in the rack so as to avoid a potentially hazardous condition due
to uneven mechanical loading.
• Circuit Overloading
When you connect the OA-740 to the supply circuit, consider the effect that
overloading of the circuits might have on over current protection and supply
wiring.
• Reliable Grounding
Maintain reliable grounding for the OA-740 and all rack-mounted equipment,
giving particular attention to supply circuits.
Note: Alcatel-Lucent strongly recommends that you provide a ground connection to the
OA-740.
