AMBTEMPOUT – Analog output reflecting the temperature of the air entering the mainframe.
This is a non-linearized signal. See

PWSOTEMP* - This low true open collector output signals a power supply over-temperature
condition. This fault condition occurs when the maximum internal temperature of the power
supply is exceeded. This signal is pulled up to +5 V with a 4.7k resistor internally.
PWSOPWR* - This low true open collector output signals a power supply over-power condition.
This fault will occur when more power is demanded from the power supply than it can provide.
This signal is pulled up to +5 V with a 4.7k resistor internally.
PWSOVOLT* - This low true open collector output signals a power supply over-voltage
condition. This fault occurs when one of the voltages produced by the power supply exceeds its
maximum value. This signal is pulled up to +5 V with a 4.7k resistor internally.
PWSOCUR* - This low true open collector output signals a power supply over-current condition.
This fault occurs when the maximum current of a voltage is exceeded. This signal is pulled up to
+5 V with a 4.7k resistor internally.
AMBOTEMP* - This low true open collector output signals a power supply over-temperature
condition. This fault occurs when the ambient air temperature exceeds 55 °C. This signal is pulled
up to +5 V with a 4.7k resistor internally.
