Step 2: SCSI Configuration

Locate the SCSI cable in your computer. One end of the cable is connected
to the SCSI host adapter card as shown below.
The width of the SCSI cable should be 50 pin.
SCSI Host Adapter Card
Note:
Carefully locate the 50 pin SCSI cable. The following types of cables may
be installed in your computer.
Find this
flat cable!
SCSI Cable
Note:
There may already be internal/external SCSI devices (like HDD, Scanner,
CD-ROM) connected to the SCSI bus cable.
In this case you have to determine the SCSI ID# of each SCSI device.
This information will be required in Step 5 "Setting the Jumpers".
Refer to appropriate SCSI device manual to find out the already used
SCSI ID# (0 ... 6).
In some cases, the SCSI host adapter is implemented on the computer's
motherboard.

Step 3: Finding the Connector

The SCSI cable should have one or more connectors on the end opposite to
SCSI host adapter card, as shown below. Trace the SCSI cable and find the
connector not in use. We recommend using the SCSI connector which is
located at the end of the SCSI cable.

Note:
If the SCSI cable inside your computer does not have a SCSI connector
free, please refer to "Additional Installation Cases" of chapter
"Troubleshooting" on page 22.

Termination
Note:
Be aware that only the last device at the SCSI bus needs to be terminated.
Pin 1 (red)
If you have not found any other SCSI device already connected to the
SCSI bus, we recommend not changing the jumper position on the rear
of the drive. In this case you can forward the installation process
refering to Step 6 "Connecting the drive".
If you found one or more SCSI devices already connected to the SCSI
bus, you have to check whether the default SCSI ID# 3 (CD-ROM
drive) was already assigned.
If SCSI ID# 3 has been already assigned to an other SCSI device, you
need to change the SCSI ID# of your CD-ROM drive to a free one.
Do this by using the jumper part (ID Select) on the rear panel of the drive.
If you connect the CD-ROM drive to the end of the SCSI cable, leave
the termination of the drive activated.
If the CD-ROM drive is not the last device at the SCSI cable, disable the
termination of the drive by removing the jumper and make sure that the
last device at the SCSI bus has a proper termination installed or activated.
