Functional Overview
Note
Software Releases earlier than 9.17(8) and 9.21(3). As a result, your system might incorrectly report
a high internal air temperature and display an airflow warning message when the internal air
temperature is actually still within the Normal operating range. If you observe this message:
issue the show environment table command and verify that the Inlet air temperature is within the
Normal range, as in the following example:
Temperature Parameters:
-
If so, even if the Airflow temperature is shown within the Warning range, ignore the message. This
is an anomaly and it will not affect operation.
The thresholds were corrected in Software Releases 9.17(8) and 9.21(2).
In the following example, all current measured values fall within the Normal status range. The first
voltage parameter in the table, +12(V), shows that the Normal range for the +12V sense spans
10.20V through 13.80V. The current measured value, 12.05V, falls within that range and is therefore
displayed in the Normal column.

In the Temperature Parameters section of the table, the airflow thresholds are incorrect in
