II. System Components
• 2-9. SCSI Backplane
The SCSI backplane of this system is comprised of two SCSI backplane boards
(DA-BP5) with 68-pin SCSI connectors (used by the system), 80-pin SCA
connectors (used by the hard drives), power inputs, and SCSI ID dip switches.
This configuration allows Ultra2 SCSI SCA hard disk drives to be docked
into the system. The DA-BP5 SCSI board does not have built-in termination.
Therefore, the included terminator block must be used on the end connector.
