CONNECTOR PINOUTS AND WIRING DIAGRAMS
Atlas 10K II Ultra 160/m SCSI disk drive interfaces include a 16-bit wide SCSI
version and a SCA-2 connector version. Connector pinout information for the drive
and signal connection diagrams are found in this section.
3.5.1 Atlas 10K II Ultra 160/m SCSI Disk Drive with 68-Pin SCSI Connector
Figure 3-7 shows the locations of the Power, SCSI, Option, and Secondary Option
Connectors on the68-pin SCSI connector version of the drive. Figure 3-7 also
provides the locations and names of the signals connected to the pins at the Option
and Secondary Option Connectors on the drive. Table 3-5 provides signal names/pin
locations for the 68-pin wide SCSI connector.
