6.
Write in the type of external single-ended drives currently con-
nected to your workstation under the heading "External Device
Drives" and each drive's SCSI device ID under the heading "De-
vice ID Number."
7.
Add your new drive to the table if it is an external device. If it is
an internal drive, continue to Step 8.
NOTICE: The C1700A Magneto-Optical Autochanger
uses three SCSI IDs, and accounts for three of
the seven devices allowed on the SCSI bus.
8.
Check to see which SCSI device IDs are not used. You may use
ID numbers 0 through 6 if they are not already in use. If the de-
fault ID on your drive does not conflict with any existing drive
IDs, use that ID. If your default address conflicts with an exist-
ing drive ID, you need to assign a new SCSI device ID to your
drive. Refer to the drive's installation documentation for infor-
mation on changing the device ID.
CAUTION: Do not use SCSI device ID 7 for any device. It
is reserved for the built-in SCSI bus controller.
