Use this information to prepare your location to facilitate the use of the IBM® Rear Door Heat Exchanger for 7014-T42.
The heat exchanger is a water-cooled device that mounts on the rear of IBM 19-inch EIA-rail and 24-inch EIA-rail Enterprise racks to cool 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. This is referred to as a secondary cooling loop. The primary cooling loop supplies the building chilled water to secondary cooling loops, air conditioning units, and so on. The hoses for the secondary cooling loop are not included with the heat exchanger kit. The rack on which you install this cooling feature can be on a raised floor or a non-raised floor. Each rear door heat exchanger can remove up to 50 000 Btu/hr (or approximately 15 000 watts) of heat from your data center.
Suggestions for sources of hoses, water treatment and cooling distribution units for supplying conditioned water are provided under Suggested sources for secondary loop components.
If you would like to procure IBM installation planning services regarding what is needed to plan for supplying conditioned water and installing the heat exchangers, see Installation and support from IBM Integrated Technology Services Offerings.
