Considerations for Multiple System Installations
When integrating a zSeries 800 system into an existing multiple-system
environment, or when adding additional systems to an installed zSeries 800,
consider the following factors:
v Thermal interactions
Figure 2-7. Multiple System Thermal Interaction
v Floor loading
v Inter-system cabling
When positioning a zSeries 800 system on your raised floor, place the machine
so that the air supplied by the perforated floor tiles is delivered only to this
system. The illustration shows how to include a zSeries 800 in an existing
arrangement, allowing for both the required service clearance and adequate air
flow.

When trying to optimize floor space utilization, floor loading may become
overlapped. Obtain the services of a qualified consultant or structural engineer if
you are uncertain of the weight distribution on your raised floor.
Integrated Cluster Bus (ICB) cables linking systems together are limited to 10
meters (33 ft) in length. Because some of that length is used under the covers of
