3.2.2 Chassis Control and Alarm Threshold Setting
Provides operational and threshold settings for the PXES-2301,
including trigger bus, PXIe link, target temperature, and fan mode,
and threshold settings for DC voltage, temperature, and cooling
fan speed.
Target Temperature
When the Fan switch on the rear panel is set to AUTO, fans run
at different speeds based on the measured temperature.
Target Temp indicates the temperature at which fans run at
100%. Using the default fan curve as an example, fans run at
30% when all temperature readings are less than 25°C, and
begin rampup when any reading exceeds 25°C.
Fans reach 100% speed if any temperature reading exceeds
65°C (i.e. Target Temperature).
Setting parameters are as shown.
