IBM XIV Gen3 Series User Manual

each heat exchanger still requires a special cut 0.6 m × 0.6 m (2 ft × 2 ft) floor tile.
However, the floor tile is positioned completely within the footprint of the rack. A
modified cable opening or independent hose cutout is used. Flexible hoses that
each contain a right-angle elbow are used to route the hoses under the rack in a
large loop to allow hose movement when the door is opened and closed. Figure 29
and Figure 30 on page 87 show how to route hoses under the rack with enough
hose length to allow the hose to move freely as the door is opened and closed.
Note: Existing tile cutouts for electrical or other cables can also be used for the
hoses, if enough space is available.
