Fault Blinking Amber
A fault was detected in this module.
Fan modules cool the chassis by circulating air through the enclosure. The rate at which air moves (the
airflow) determines the amount of cooling. This airfl ow is a function of fan speed (rpm). These fans
can operate at multiple speeds. This ensures that when the enclosure temperature changes, the fans
can automatically adjust the airflow. If one fan operates too slowly or completely shuts off, the other
fan operates at a higher speed. At the same time, the error condition is reported to the user via the
LCD panel on the front of the controller.
