Cooling fan sensor descriptions
During a shutdown, the cooling fans do not shut off. This allows the chassis to continue cooling.
Temperature Sensors
Extreme high and low temperatures can cause significant damage if they go unnoticed. Each controller
module has six temperature sensors. Of these, if the CPU or FPGA temperature reaches a shutdown value,
the controller module is automatically shut down. Each power supply has one temperature sensor.
When a temperature fault is reported, it must be remedied as quickly as possible to avoid system damage.
This can be done by warming or cooling the installation location.

Controller module temperature sensor descriptions
When a power supply sensor goes out of range, the Fault/ID LED illuminates amber and an event is posted
to the event log.
