# Water cooled Witherspoon fan policy for PDM.
#
# A water cooled Witherspoon requires a minimum of two functional fan
# enclosures or four functional fan rotors across all enclosures.
# If the number of functional fan enclosures is below two, soft poweroff
# the system, whereas if the number of fan rotors drop below four, an
# immediate hard poweroff of the system occurs.
