COOLING SPECIFICATIONS
COOLING REQUIREMENTS*
Low Fan Speed	56 W/slot for a 10°C Rise
	84 W/slot for a 15°C Rise
High Fan Speed	80 W/slot for a 10°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
