Fans
The Cisco Nexus 2300 Series platform has three, hot-swappable independent fans with support for 2+1
redundancy. Depending on the arrangement of hot and cold aisles in your data center, you can order
port-side exhaust airflow to position the fan side of the FEX chassis in a cold aisle or port-side intake
airflow to position the back of the FEX chassis in a cold aisle. Table 1 -2 lists the part numbers for each
of the fans that you can use with the Cisco Nexus 2300 Series chassis.
Note Blue color coded tabs indicate port-side exhaust airflow. Red color coded tabs indicate port-side intake
airflow.
Caution Always make sure that all of the fan and power supply modules have the same direction of airflow and
the same color designation for that airflow direction. The switch does not support having more than one
direction of airflow with its modules.
To replace a fan, see the “Removing and Installing a Fan” section on page4-19.
