2.3 Narrow Addressing Setting

The large Hub can be used with SCSI bus architectures that are limited to eight
ID assignments, such as DIGITAL UNIX 4.x and earlier versions. (Figure 2-2
shows narrow ID assignments). The jumper on the rear of the Hub (Figure 2-3)
must be closed to make the Hub respond to SCSI IDs 3 – 0 on the host ports.
