2.1.3.2 Module ID Switch
Ensure that the module IDs for the StorEdge D1000 disk arrays are set according to
TABLE 2-2.
Facing the front of the expansion cabinet:
■ controller module A controls the right side of disk arrays 1 through 3 and all of
disk arrays 4 and 5.
■ controller module B controls the left side of disk arrays 1 through 3 and all of disk
arrays 6 and 7.
This configuration is shown in
FIGURE 2-17.
2.1.3.3 SCSI Jumper Cables and Terminators
The top four disk arrays should have SCSI jumper cables between the middle SCSI
connectors (IN/OUT-1 and IN/OUT-2) and a differential SCSI terminator in the far
right SCSI connector (IN/OUT-2).
The bottom three disk arrays should have differential SCSI terminators on the inside
IN/OUT-1 and IN/OUT-2 SCSI connectors. This configuration is shown in
FIGURE 2-17.
