the fan speed remains under the 4000 RPM threshold, the internal enclosure
temperature may continue to rise. Replace the power-and-cooling module reporting
the fault.
During a shutdown, the cooling fans do not shut off. This allows the enclosure 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-and-cooling module 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.
