5: Cabling
To complete these procedures, you will need at least two interface cables (depending on
the number of drive expansion enclosures in the array).
1. Connect the drive loop in the first two enclosures (see Figure 5-3). Starting with the
controller enclosure, connect an interface cable from the drive loop connector on the
left RAID controller module to the
drive channel in connector on the left ESM.
Figure 5-3 RAID Controller With Single Connection Drive Cabling Example
2. Connect an interface cable from the drive loop connector on the right RAID
controller module to the
drive channel out connector on the right ESM. This creates a
redundant drive loop between the two enclosures. Table 5-1 lists the specific
connection points.
