Site Preparation
• The Alpine 3800 series chassis require 3 inches (7.62 cm) on both the left and right sides of the switch
(5 inches (12.7 cm) recommended) for proper airflow.
• The BlackDiamond 6816 and 6804 chassis require 3 inches (7.62 cm) around the entire chassis—front,
rear, and sides—(5 inches (12.7 cm) recommended) for proper airflow.
• The BlackDiamond 6808 chassis requires 3 inches (7.62 cm) around both the front and rear of the
chassis (5 inches (12.7 cm) recommended) for proper airflow.
The airflow of the Summit family of switches moves from the left side of the switch to the right side of
the switch, or from the right side of the switch to the left side of the switch depending on the model.
The airflow of the Alpine 3808 moves through the power supplies and is independent of the airflow
through the chassis as shown in Figure 4. 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 enters the top of the chassis and moves left to right as you face
the chassis.
• Airflow for cooling modules moves left to right as you face the chassis.

The airflow of the Alpine 3804 and Alpine 3802 moves from the left side of the chassis to the right side
of the chassis as shown in Figure 5 and Figure 6.
• Airflow for cooling power supplies moves left to right as you face the chassis.
• Airflow for cooling modules moves left to right as you face the chassis.
