ARO-1130CA Installation and Hardware Guide

Connecting SCSI Devices

The ARO-1130CA supports both internal and external SCSI devices.

Depending on the number of SCSI channels provided on the moth-

erboard. Each channel supports up to 15 SCSI devices—either 16-bit

devices alone or a combination of 16-bit and up to seven 8-bit

devices.

Note:

If you are installing your SCSI devices inside an array

enclosure, see Connecting SCSI Array Enclosures (Storage Sub-

systems) on page 2-12.

Choosing SCSI Cables

To connect your SCSI devices, make sure you have the appropriate

cable and connectors as described in the following table (see also

Cable Lengths on page 2-13 for additional information on cabling SCSI

devices):

Use only high-quality external cables with a single-ended impedance range of 80-110 ohms.
