Installing a Frame
This section outlines how to install an openGear frame. The same procedure is used to install a frame
regardless of the model of frame unless otherwise noted.
Overview
The openGear frame mounts in the rack frame by means of four rack screws fastened through the front
mounting ears. This should normally be sufficient to carry the load, including the weight of
accompanying cables. However, in certain applications such as mobile truck installations, it may be
desirable to also support the rear of the frame. The optional Rear Support Bars and Brackets are
specifically engineered to compensate for extra load stress. Refer to the section “Installing Rear
Support Bars and Brackets” for bracket installation instructions.
Installation Requirements
Keep the following in mind when installing your frame:
• Install the frame for maximum stability during operating 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.
Frame Dimensions
Note that each openGear frame installs in a standard 19” rack.

OG3-FR Series Frame Mounting 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 OG3-FR series 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..
