Rear-door heat exchanger

The rear-door heat exchanger (feature code AFR1) is an optional water-cooled
device that is mounted on the rear of an IBM FlashSystem A9000R system. It cools
the air that is heated and exhausted by devices inside the rack.
A supply hose delivers chilled, conditioned water to the heat exchanger. A return
hose delivers warmed water back to the water pump or chiller (referred to as the
secondary cooling loop).
