conditions, there is no requirement for extra vertical spacing between the frames. The OGX-FR frames can be
stacked one on top of the other, a feature that is highly desirable in densely crowded rack frame environments.
Airflow Requirements
Under some conditions, the ambient air temperature inside rack-mount cabinets can be greater that the ambient
temperature within a room. For safe long term reliability, ensure the ambient air temperatures at the OGX-FR frame
front intake area are within the product’s specified operating temperature range. Adequate ventilation within a rack
frame must also be maintained. Ensure to adhere to the following clearance recommendations:
• Minimum 2” (5.08cm) clearance both right and left-hand side of the chassis sides with unrestricted vertical
airflow.
• Minimum 5” (12.7cm) clearance at the chassis rear with unrestricted vertical airflow.
Installation Requirements
Keep the following in mind when installing your OGX-FR frame:
• Install the frame for maximum stability during operation and in such a way as to allow adequate ventilation.
• The frame cannot be sealed in a closed container and must be installed in free air space where the ambient
temperature is monitored and controlled to not exceed 40°C (104°F) at the frame front door airflow intake.
• Ensure that adequate space exists in front and behind the frame and on both sides of the frame for airflow
exhaust.
• The location of the frame should be accessible, dry, and dust-free.
Installing the Rear Support Bars and Brackets
Under normal conditions, mounting the OGX-FR frame to the front of the rack with four rack screws should be
sufficient to carry the load, including the weight of accompanying cables.
To help reduce mechanical stress due to cable weight, the FSB-OGX rear support brackets are available for the
OGX-FR frame. The FSB-OGX are specifically engineered to compensate for extra load stress associated with
certain applications, such as mobile truck installations, to also support the rear of the OGX-FR frame.
Installing the FSB-OGX
This section describes how to attach the FSB-OGX rear support bars to a OGX-FR frame.
The FSB-OGX cannot be installed on the DFR-8321 or DFR-8310 frames.
To install the FSB-OGX
1. Attach the Rack Mount Arms of the FSB-OGX to the OGX-FR frame.
Caution
— The two sides of the OGX-FR frame have perforations that are needed to ventilate the
power supplies and must not be blocked.
