3. Slip the top of the 2RU rear module into
the slot at the bottom of the adapter,
and secure it to the frame using the
captive screw at the bottom of the
module.
NOTE:
Native 3-RU single and double rear modules
are also available for some Densité 2 cards
to optimize chassis configuration by providing
maximum density (e.g. maximum number of
supported Audio or Video connections) in a
single or double 3-RU slot.
•
Cards which required a double-width
rear in a Densité 2
frame may only
need a single-width rear in a Densité 3
frame, freeing up a slot for another
card.
•
Cards which required a triple-width rear
in a Densité 2
frame may only need a
double-width rear in a Densité 3 frame,
freeing up a slot for another card.
2.6 Ventilation
Ventilation for the frame is provided by a fan mounted in the center of the rear panel. The fan draws air through
the frame and exhausts it to the rear. Ventilation slots are provided in the front panel to allow air to flow into the
frame, and an air filter is mounted in the frame door.
Important Note: to ensure proper cooling, the front panel of the Densité 3 frame must be closed at all times
when cards are installed and operating
The frame-mounted fan is supplemented by two thermostatically-controlled fans mounted in each power
supply. These are not field-serviceable.
Ensure that the front panel ventilation slots are not obstructed. Check the air filter regularly to ensure that it is
not plugged up with debris. The filter may be cleaned by rinsing in warm water. Dry thoroughly before replacing
it in the frame. See section 3.4 for details.
