Replacing a Fan Tray
Caution Be sure that the replacement fan tray has the correct direction of airflow, which means that it takes in air
from the cold aisle and exhausts air to the hot aisle. It must also have the same direction of airflow as
the power supplies. Otherwise, an overtemperature condition can occur.
