Power Supply Module Fan

Each installed power supply module includes one embedded (non-removable) 40-mm fan. It is
responsible for airflow through the power supply module. If this fan fails, the power supply will
continue to operate until its internal temperature reaches an upper critical limit. The power
supply will be protected against over temperature conditions caused by loss of fan cooling or
excessive ambient temperature. In an over temperature protection condition, the power supply
module will shut down.
