Cabling The Devices; Figure 6-4 Using The Correct Cables Between Devices And/Or The Octane2 - Silicon Graphics Octane2 Owner's Manual

Cabling the Devices

Caution: Ultra and Fast SCSI devices require higher quality cables than earlier SCSI
devices. Use the cable and active terminator included with the device. Using other types
of cables or terminators can cause your system to malfunction.
1. Choose the required SCSI cable to connect your 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 your workstation and to each other,
then connect slower devices at the end of the chain. See Figure 6-4.
