DESCRIPTION
This field displays Normal for temperatures below the threshold and Error
for those above.
A properly functioning fan is an essential component (along with a
sufficiently ventilated, cool operating environment) in order for the device
to stay within the temperature threshold. Each fan has a sensor that is
capable of detecting and reporting if the fan speed falls below the
threshold shown.
This field displays this fan's current speed in Revolutions Per Minute (RPM).
This field displays this fan's maximum speed measured in RPM.
This field displays this fan's minimum speed measured in RPM. "<41" is
displayed for speeds too small to measure (under 2000 RPM).
This field displays the minimum speed at which a normal fan should work.
Normal indicates that this fan is functioning above the minimum speed.
Error indicates that this fan is functioning below the minimum speed.
The power supply for each voltage has a sensor that is capable of
detecting and reporting if the voltage falls out of the tolerance range.
This is the current voltage reading.
This field displays the maximum voltage measured at this point.
This field displays the minimum voltage measured at this point.
This field displays the percentage tolerance of the voltage with which the
Switch still works.
Normal indicates that the voltage is within an acceptable operating range
at this point; otherwise Error is displayed.
