Ventilation and Cooling
This frame has been specially engineered to minimize internal heat buildup and thus improve card
reliability. However, for long-term reliability and increased product life of the DFR-8310 frame
(without the Cooling Fan Module installed), it is recommended that the total power dissipation of all
cards installed in the frame should not exceed 40W, and to leave an empty 1RU panel space above and
below the frame for improved heat dissipation. For information on the power dissipation of openGear
cards, refer to the openGear Product Catalog or visit our website.
For applications using less than 40W in a non-ventilated frame, but where the individual card power
consumption is greater than 8W, the cards should be evenly distributed in the frame. This will prevent
the creation of concentrated heat, or unbalanced heat-rise areas, in the frame.
Notice — Sierra Video recommends that you periodically clean the filter in the
frame door to maintain optimal airflow and cooling through the frame. Open the
door, for no longer than 5 minutes, and use a vacuum to clean the filter. Never use
water or other cleaning agents to wash the filter.
DFR-8310 Series Frames
For applications that require greater heat dissipation, or where the card power consumption is greater
than 40W, it is necessary to use the DFR-8310-C frame (with Cooling Fan Module installed), or to
install the CFM-8310 Cooling Fan Module field upgrade option. When the Cooling Fan Module is
installed, the frame and PS-8300 can supply up to 120W of card power. Under these ventilated
conditions, there is no requirement for extra spacing between the frames. The DFR-8310-C (or DFR-
8310 with CFM-8310 option) can be stacked one on top of the other, a feature that is highly desirable
in densely crowded rack frame environments.
Notice — For reliable performance, it is recommended that the frame door not be
opened for longer than 5 minutes when using the Cooling Fan Module option on
frames loaded with more than 40W.
DFR-8321 Series Frames
The DFR-8321 series frames come standard with a Cooling Fan Module. The frame and PS-8300 can
supply up to 120W of card power. Under these ventilated conditions, there is no requirement for extra
spacing between the frames. The DFR-8321 series frames can be stacked one on top of the other, a
feature that is highly desirable in densely crowded rack frame environments.
Notice — For reliable performance, it is recommended that the frame door not be
opened for longer than 5 minutes on frames loaded with more than 40W.
