Typical 2mm Drive ID Pin Configuration
Figure 7 illustrates a typical ID select connection to a drive with 2mm ID select pins. In most
cases, the drive manufacturer labels each pair of ID select pins in their significant bit order
(0, 1, 2, 3 as shown in Figure 7). 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 device manufacturer's
documentation for additional pin numbering and jumper option information.
Attach the 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 carrier. Refer to the manufacturer’s documentation to disable
termination on the drive.
