Internal Connections (Models 500 and 600)

|
| Inside the 7133, the disk drive modules are connected in strings of four modules. These
| strings are connected to the external SSA connectors at the back of the 7133.
| The following diagrams show the relationships between the disk drive module strings and
| the external SSA connectors at the back of the 7133 Model 500 and the 7133 Model 600.

| Table 1-2 summarizes the relationship between the disk drive module strings and the
| external SSA connectors.
Important: If you are connecting strings of disk drive modules to each other on a
Model 500, ensure that you connect the disk drive modules in the correct (numeric)
sequence on the loop or loops. For example, if you are connecting disk drive modules 1
