A.4 Hard Disk Id Setting Options; A-4 Id Cable Connector Pin Definitions - Acer Altos 9100B User Manual

A.4 Hard Disk ID Setting Options
The wide SCSI hot-swap drive tray includes an 8/12-pin ID cable (see Figure 2).
This cable allows you to define the hard disk ID using the ID switches on the
backplane board.
The narrow SCSI drive tray comes with a 6-pin ID connector but no cable since
narrow SCSI drive specifications vary depending on the brand. The ID setting
feature on the backplane board does not work if you do not connect an ID cable.
Figure A-4 shows the pin definition of ID cable connector J2 on the drive tray to
help you connect the cable properly. Make sure to match pin 1 on the cable with
pin 1 on J2.

If you are using a narrow SCSI drive tray and
you want to use this feature, ask your vendor
for information on the ID cable that
corresponds to your SCSI hard disk drive.
