Hoses that exit the heat exchanger are routed in a manner similar to that of power
cables in a non-raised-floor data center. For example, place the hoses side-by-side
and allow them to move freely as they approach the rack (within approximately 3
meters [10 feet] of the rack). When you open the door, it is acceptable for the hoses
to move slightly and rotate in parallel at the coupling interface inside the door. As
you close the door, the hoses rotate back to their original positions.
Note: When you open or close the door, some manipulation of the hose along the
floor might be necessary to prevent unwanted forces on the door and to make it
easier to open and close the door.
Hose coverings or protective devices are not provided by IBM. Routing and
protection of the hose assemblies exterior to the rack are your responsibility.
Secondary cooling loop parts and services information
IBM supplies a heat exchanger that is designed for IBM enterprise-server racks, a
hinge kit (for those racks), and an air purge tool. This information provides sources
and information for other parts and services that are needed for correct function
and reliability of the secondary cooling loop.
