DSP2022-S SCSI Disk Drive Installation Guide

Locate the SCSI Connector

Locate the SCSI 50-pin connector shown at the rear of
the drive in Figure 1 . This connector is used for cable
installation later. Note that the pins of the SCSI connector
are divided into two pin fields: one for the SCSI interface
signals and the other for the vendor-specific options. Learn
the use of these two pin fields in the following sections.
