Installing the ARO-1130CA and Connecting SCSI Devices
Connecting Internal SCSI Devices
Follow these steps to connect internal devices:
1
Prepare each SCSI device for installation.
■
Make sure each device (internal and external) is assigned a
unique SCSI ID number from 0 to 15—no duplicate IDs are
permitted on a channel. (See SCSI ID Numbers on page 2-14
for additional information.)
■
Install (or enable) the terminators on the internal device
you are attaching to the end of the cable only. (See SCSI Ter-
mination on page 2-14 for additional information.)
2
Install and mount each internal SCSI device in an available
drive bay inside your computer. (Refer to your computer and
device documentation for instructions.)
3
If you are connecting 8-bit internal SCSI devices, attach one end
of the 50-pin cable to the 50-pin internal SCSI connector on the
motherboard. If you are connecting 16-bit internal SCSI devices,
attach one end of the 68-pin cable to the 68-pin internal SCSI
connector on the motherboard. Figure 2-5 shows a typical instal-
lation of a 68-pin cable.
