Meeting Site Requirements
• 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
air flow.
• 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 air flow.
The air flow 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 air flow of the Alpine 3808 moves through the power supplies and is independent
of the air flow through the chassis as shown in Figure 2-1. For example, if the power
supply fans fail, the air flow through the module area of the chassis will not cool down
the power supplies.
• Air flow for cooling power supplies enters the top of the chassis and moves left to
right as you face the chassis.
• Air flow for cooling modules moves left to right as you face the chassis.
