One DS3950 and one storage expansion enclosure
If you are cabling one DS3950 storage subsystem to one storage expansion
enclosure, Figure 36 shows the correct cabling topology.
Note: Figure 36 illustrates the drive channel connections between the DS3950 and
the storage expansion enclosures. Do not use Figure 36 as the cabling
diagram. Follow the instructions in “DS3950 storage subsystem and
