Site Preparation
The airflow of the BlackDiamond 6800 series chassis moves through the power supplies and is
independent of the airflow through the modules as shown in Figure 4, Figure 5, and Figure 6. For
example, if the power supply fans fail, the airflow through the module area of the chassis will not cool
down the power supplies.
• Airflow for cooling power supplies moves front to back as you face the chassis.
• Airflow for cooling modules moves left to right as you face the chassis.
