Typical 2MM Drive ID Pin Configuration
Figure below illustrates a typical SCSI ID select connection to a drive with 2mm
ID select pins. The wires on the wire harness connect to the positive pin (or
signal pins) on the disk drive. In some cases, the drive manufacturer will label
the signal pins as Pin 1, 3, 5, 7, (instead of 0, 1, 2, 3 as shown in figure below).
Also, in some cases, the even-numbered Pins 2, 4, 6 are used for Ground.
Attach the ID select cable to the drive using the 2mm connectors. Align the
“ID0” pin with the black wire. Attach the 1.25mm connector on the other
end of the ID select cable to the 1.25mm connector (J3B) provided on the
signal distribution board, located inside the carrier. Refer to the manufactur-
er’s documentation to disable termination on the drive.

NOTE: The lock on the Data Express receiving frame functions as a lock and a
DC power switch for the carrier unit. The lock MUST be engaged (turned coun-
terclockwise) in order to supply power to the carrier and installed drive unit.
