When a node is not inserted in a bay, an airflow damper closes in the midplane to
prevent air from being drawn through the unpopulated bay. By inserting a node
into a bay, the damper is opened, thus allowing cooling of the node in that bay.
Table 3-3 shows the relationship between the number of fan modules and the
number of nodes supported.

Chassis area: The chassis area for the node is effectively one large chamber.
The nodes can be placed in any slot; however, preferred practices indicate
that the nodes need to be placed as close together as possible to be inline
with the fan modules.
