THE
OA-780
The OA-780 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-780 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-780.
To rack-mount the OA-780, consider the following guidelines:
•
Maximum recommended operating temperature
The maximum recommended operating temperature for the OA-780, 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-780.
•
Reduced Airflow
Install the OA-780 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-780 in the rack so as to avoid a potentially hazardous condition due
to uneven mechanical loading.
•
Circuit Overloading
When you connect the OA-780 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-780 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-780.
