Note that the heater and fan outputs are logical outputs that become 3.3V when they are active. If
necessary, the user must provide driving circuitry to drive an actual heater and fan. The positions of
the two outputs in CN2 are shown here.
If the temperature is too cold or too hot, the CPU cannot be turned on until it changes to cool or
warm. But if it the CPU is on, and the temperature later changes to too cold or too hot, the CPU
continues running.
If the temperature changes to too hot and you are using UPS monitoring software with the RS232
status signals, a “critical alarm” (mains failure and low battery) is signalled, prompting the
monitoring software to shut down immediately. UPS monitoring software that reads status
information through the PC/104 can also detect this condition and react accordingly.
