CHAPTER 2: Introduction
2.2 Description
With the SCSI Switch II, you can switch between one “main” SCSI bus and
three “branches.” Both the main bus and the branch buses may have any
combination of SCSI initiators (host computers) and targets (disk drives,
scanners, tape drives, etc). There is no difference between the main bus and
the three branches except for the way they are routed through the Switch:
Figure 2-1. Routing of Main Bus and Thre Branch Buses.
The SCSI Switch II supports the common “single-ended” SCSI interface.
The main-bus connector on the back of the SCSI Switch II (labeled INPUT)
is a female high-density 68-pin receptacle. There are three branch-bus
connectors (labeled A, B, and C). Each one is a high-density 68-pin
connector.
