Spacing Requirements
Extreme Networks recommends placing no more than three chassis next to each other due to chassis-to-
chassis heating. The following are some general recommendations for installing your Extreme Networks
switch:
A minimum of 17.32 inches (44 cm) between each set of three Extreme Networks switches.
or
Place patch panels, which are used to patch cables together, between each set of three Extreme
Networks switches. A patch panel does not require any power and does not generate any heat.
NOTE
Up to five adjacent switches 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
To ensure proper airflow through an Extreme Networks switch, refer to the following recommendations
when you are installing your switch:
●
Extreme Networks switches require 3 inches (7.62 cm) around both the front and rear of the chassis
for proper airflow. Extreme Networks recommends 5 inches (12.7 cm) clearance.
The airflow of a BlackDiamond 10K series and Aspen switch moves through the power supplies and is
independent of the airflow through the modules as shown in Figure 1 and Figure 2 . For example, if the
power supply fans fail, the airflow through the module area of the chassis will not cool down the power
supplies. The direction of the airflow is as follows:
●
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.
