2Locate the ID number indicator and switch (usually on the back panel of the SCSI

device).

3Check the ID numbers of all the devices you want to connect.

If all the devices have unique ID numbers, you can continue with the next

section, “Checking That the SCSI Chain Is Properly Terminated.”

4If you need to change a device’s ID number, choose an available number between 1

and 6.

IMPORTANT

Hard drives installed in the Duo Dock or Duo Dock IIare preset

to have a SCSI ID number of 1. SCSIdevices connected to a Duo Dock or

Duo Dock II should use SCSIID numbers 2 through 6.

5Press the appropriate button to increase or decrease the SCSI ID number.

If your SCSIdevice does not have an IDnumber switch like the one pictured

above, consult the manual that came with your SCSIdevice for details.
