COOLING SPECIFICATIONS
COOLING REQUIREMENTS*
Low Fan Speed
High Fan Speed
56 W/slot for a 10°C Rise
84 W/slot for a 15°C Rise
80 W/slot for a 10°C Rise
120 W/slot for a 15°C Rise
*Calculated using VXI-8 Rev. 2.0 standards
COOLING MODES
High or low speed cooling modes can be selected by moving the Fan Speed
switch at the rear of the chassis. The power supply and modules are cooled by
separate fans.
AIR FLOW PATH
Air is drawn into the chassis from the rear and is pressurized below the cards.
The air is then distributed across all slots along the total length of each slot and
is exhausted through the top of the mainframe. When the mainframe is rack
mounted, allow approximately 2 inches (50 mm) of clearance at the top and rear
for proper airflow.
ACOUSTIC NOISE
High Speed Fan Mode < 40 dBA
Low Speed Fan Mode < 30 dBA
