Claim 19:
20. The method of claim 12, further comprising:
determining the current real time volumetric airflow rate of the cooling air circulated by the at least one cooling fan from the cooling air inlets to the cooling air outlets through the enclosed interior of the chassis enclosure to be a volumetric airflow rate value from a relationship between values of electric power consumption of the at least one cooling fan and values of volumetric airflow rate provided by the at least one cooling fan that corresponds to the determined current rotational speed of the at least one cooling fan; and
where the method further comprises predefining the relationship between values of electric power consumption of the at least one cooling fan and values of volumetric airflow rate provided by the at least one cooling fan that corresponds to the determined current rotational speed of the at least one cooling fan by measuring values of electrical power consumption by the at least one cooling fan at different volumetric airflow rates of the least one cooling fan while the at least one cooling fan is operating at a given rotational speed that corresponds to the determined current rotational speed of the at least one cooling fan.
