TYPICAL 2MM DRIVE ID PIN CONFIGURATION
Figure 9 illustrates a typical SCSI ID select connection to a drive with 2mm ID select pins. In
most cases, the drive manufacturer labels each pair of SCSI ID select pins in their significant
bit order (0, 1, 2 as shown in Figure 9). In other cases, the manufacturer does not label these
pins in their significant bit order, but instead, assigns pin numbers only. In any case, all odd
numbered pins or all even numbered pins will be the signal row. The wires on the wire
harness connect to the positive pin (or signal pins) on the drive. Refer to the drive
manufacturer's documentation for additional pin numbering and jumper option information.
Attach the .1 inch/2mm ID select cable to the drive using the 2mm connectors. Align the “ID0”
pin with the black wire. Attach the other end of the ID select cable to the ID select connector
located on the carrier board, inside the drive carrier. Refer to the manufacturer’s
documentation to disable termination on the drive.
