4. Plot the 1260-82 operating point (Pressure, Airflow) against the
chassis cooling curve. If the module operating point lies under
the chassis curve, the module should remain within the
specified temperature. An example of a 1260-82 Module in a
Racal 1261B VXI Chassis is shown in Figure 3-4. The
chassis airflow plotted is for the "worst case" slot airflow. In
the 1261B chassis, the 1260-82 could be placed in any slot
without much concern for the temperature rise of 10 °C being
exceeded.
CAUTION
The required airflow may need to be increased
depending on airflow distribution across the module,
the ambient temperature and reliability issues. Consult
the VXI specification for more details.
