BlackDiamond 6816 Spacing Requirements.
Due to chassis-to-chassis heating, Extreme Networks
recommends placing no more than three BlackDiamond 6816 chassis next to each other.
The following are some general recommendations for installing your BlackDiamond 6816 chassis:
•
A minimum of 17.32 inches (44 cm)
between each set of three BlackDiamond 6816 chassis.
Or
•
Place front-back cooled equipment, such as a BlackDiamond 6808 chassis, between each set of three
BlackDiamond 6816 chassis.

Or
•
Place patch panels, which are used to patch cables together, between each set of three BlackDiamond
6816 chassis. A patch panel does not require any power and does not generate any heat.

NOTE
Up to five adjacent BlackDiamond 6816 chassis will continue to function without safety concerns.
However, product lifetime may degrade with continued exposure to high temperatures in close proximity
and long term reliability may be compromised.

Airflow Requirements.
Cooling of an Extreme Networks switch requires proper airflow through the
chassis. Make sure there is space around the installed switch for airflow and that cables or other
equipment do not block the air intake or outflow vents on the Extreme Networks switches. It is best to
have 3 to 5 inches (7.62 to 12.7 cm) of clear space in front of the air intake and outflow vents on the
switches. Depending on other conditions in the equipment room or wiring closet, it may be possible to
install the switches closer to each other. Consult your Extreme Networks Customer Support
representative for guidance.

For proper airflow through the switch, leave clear space around the switch as follows:
•
Summit family of switches—left and right sides of the switch
•
Alpine 3800 series chassis—left and right sides of the switch
•
BlackDiamond 6816 and 6804 chassis—around the entire chassis (front, rear, and sides)
•
BlackDiamond 6808 chassis—front and rear of the chassis
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 1. 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.
