Chapter 6: Installing and Removing External Devices
Cabling the Devices
Caution: Ultra and Fast SCSI devices require higher quality cables than earlier SCSI
devices.Use thecableandactive terminatorthatcamewiththe device.Usingothertypes
of cables or terminators can result in your system malfunctioning.
1. Choose the appropriate SCSI cable to connect the external SCSI device.
Caution: Exceeding the maximum 1.5 or 3 meters combined cable length
recommended for your SCSI type can cause your external SCSI devices to operate
unreliably. (See Table 6-3 for maximum cable length for each type of device or
combination of devices.)
2. Connect the fastest SCSI device or devices to the OCTANE workstation and each
other, then connect slower devices at the end of the chain. See Figure 6-4.
