Figure 40: Installing a Fan Module in a QFX5110
CAUTION: Damage can occur if you attempt to install a fan module into
a chassis with a different airflow direction. Compare the switch product
SKU with the airflow marking on the handleto ensure thatyou are installing
a fan module with the same airflow direction as the chassis. The fan
modules are designed so that they can only be inserted into the QFX5110
product SKU that supports the same airflow type. See “QFX5110 Cooling
System and Airflow” on page 25 for more information.
