Figure 60, Figure 61 on page 130, Figure 62 on page 131, and Figure 63 on page 132 illustrate connecting a
SAS adapter to one, two, three, or four disk expansion drawers. It is also possible to connect three disk
expansion drawers by omitting one of the cascaded drawers that are shown in Figure 62 on page 131.
Disk expansion drawers can be cascaded only one level deep.
