Each airflow type requires specific power supplies and fan trays that have fan modules
oriented in the proper direction. The fan trays are designed so that they can only be
inserted into the device model that supports the same airflow type. The power supplies
have labels and arrows on the handles that depict the direction of airflow (see
Figure 71 on page 109). The label
airflow.
CAUTION: Verify that the direction of the arrow on the power supply handle
matches the direction of airflow in the chassis. See
