Interface Connectors and Cables
Connector Dimensions and Locations
The physical locations and dimensions of the interface connectors are shown in the respective
appendices for each interface PCA. Refer to Table 2-1 for a list of these appendices.
SCSI Connector
The SCSI device connector is a nonshielded 50-pin (narrow drives) or a 68-pin (wide drives)
connector. The physical construction and pin assignments for the connectors conform to
SCSI specifications. Mating connector information is listed in Table 2-3. The connector pin
assignments are listed in the respective appendices for each interface PCA (refer to Table 2-1).
DC Power Connector
Power requirements for the disk drive are listed in Chapter 1. Pin assignments for the dc
power connector are shown in the respective appendices for each interface PCA (refer to Table
2-1). Mating connector information is listed in Table 2-3.
