Setting the SCSI Address on the External Device

Now you must manually set the address you chose in step 5 above on the external device.
This may be done in a number of ways, depending on the device. In some cases, it may
mean installing jumpers on the device.
If the device has a switch or dial on the back, follow the steps below. If there is no switch
or dial on the device, see the instructions included with the device.
1. Take the device out of its box.
2. Locate the address dial on the back of the device.
Caution: Do not assign number 0! This number is reserved for the SCSI controller.
3. Click the dial buttons or turn the dial with a screwdriver to assign the drive the
number you chose in step 5 above.

Attaching the Device

You can attach one or more external devices to the SCSI port on the back of your
workstation. Connecting more than one device is called daisy chaining. The devices are
connected together in a chain, with the first device attached to the SCSI port on the
workstation.
If one or more of the devices you are attaching to your workstation is a FAST SCSI-2
device, then the maximum combined cable length of all SCSI cables should not exceed 3
meters. If you are not attaching any FAST SCSI-2 devices, then the maximum combined
cable length of all SCSI cables should not exceed 6 meters.
Use the cables and active terminator that came with the device. You must use an
Note:
active terminator. Using other types of cables or terminators can result in data loss. If you
have a device that you want to attach to your system, but you do not have the
appropriate cables, you can order them by contacting your service provider.
