Cooling and Airflow
Signal Chassis
The 8150 dissipates less than 900 thermal watts. Four fans, two internally
mounted and two mounted at the chassis rear, draw air through the front
cover, over the circuitry, and out the chassis rear. Figure 2-1, below,
shows the air flow direction. Allow at least six inches (152mm) at the
chassis rear for ventilation.
NOTE: All eight input module locations must have either
a module or a blank plate installed for proper cooling air
flow inside the chassis.
Control Panel
The 8150 Control Panel does not require special cooling considerations.
Ensure that the Control Panel modular power supply has adequate
clearance for proper ventilation.
