Rear-door heat exchanger feature

The rear-door heat exchanger (feature code 0082) is an optional water-cooled device that is mounted on the rear of an IBM® XIV® Storage 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). The primary cooling loop supplies the building chilled water to secondary cooling loops and air conditioning units. The hoses for the secondary cooling loop are not included with this option.

The rack on which you install the heat exchanger can be on a raised floor or a non-raised floor.

The rear-door heat exchanger option consists of the following components that are shown in Figure 1.
  • Door assembly
  • Hinge kit
  • Air-purge tool
