This configuration is shown in FIGURE 2-17.

2.1.3.3SCSI 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.
