Troubleshoot/Problem Solving 151
NOTE: Figure 124 on page 162 provides a representative example of the controllers used in the
RAID chassis.
Figure 125 on page 163 provides a representative example of the IOMs used in the expansion chassis.
The QXS-G2-412, QXS-G2-424, and QXS-G2-484 systems use the same identical controllers and IOMs.
