Cooling System
The cooling system of the SSR1200 consists of two fixed fans. The fan controller on the appliance
monitors the temperature of the chassis and adjusts the fan speed according to the temperature. The
SSR1200 appliances have front-to-back airflow. The air is pulled in through the front of the chassis
toward the fan modules, from where it is exhausted out of the chassis. The fans are not field-
replaceable.
