Initial setup information

For the initial setup connect the cables, set the SCSI bus address and enable or disable (as required by system configuration), the SCSI I/O line terminator resistors (model "W" drives only). Note whether the drive model number ends in W, WC or WD. These procedures are described in paragraphs following.

SCSI interface cable connection

The drives covered by this manual are SCSI interface drives. For "W" and "WD"" models, system connection is via a 68 pin, SCSI connector. For "WC" models system connection is via an 80 pin SCSI connector. Normally "WC" models plug directly into a PCB or bulkhead mounted mating 80 pin connector. Pin 1 is noted in Figures 1a and 1b. Some cables have a contrasting color stripe on one edge to indicate pin 1. The I/O connector is keyed by virtue of its shape. There is only one way it can mate with the mating input connector. Strain relief is recommended at the cable for drives using cables. Do not block system cooling air flow in routing of cables.

DC Power connection

Model ST12400W/WD family drives receive DC power through a 4 pin connector mounted on the PCB next to the SCSI I/O connector. See Figure 1.
