# Air cooled Witherspoon fan policy for PDM.
#
# An air cooled Witherspoon requires a minimum of three functional fans
# enclosures or six functional fan rotors across all enclosures.
# If the number of functional fan enclosures is below three, soft poweroff
# the system, whereas if the number of fan rotors drop below six, an
# immediate hard poweroff of the system occurs.
