Cooling Fans
Two internal fans ensure proper airflow to cool system components in the base unit. One fan is
installed in a housing at the front of the base unit chassis. Another fan is secured to the rear of the
base unit chassis, and has a cooling duct to direct the airflow over the system’s processors.
CAUTION
Arrows on each fan indicate airflow direction and rotation. Install each fan with the
airflow arrow pointing into the chassis to ensure proper cooling of system
components.
To replace the front fan:
