MOUNTING SCSI DRIVES
The V1 is factory set to SCSI ID6 by setting DIP switches 1, 2 & 3 on the back of the V1 to high, low &
low. To avoid conflicts, Don't use this ID 6 for any drive to be installed.
CAUTION NOTE: FOR VENTILATION PURPOSES, THE OPENEING OF THE TOP COVER
SHOULD ALWAYS BE TOWARDS THE HARD DISK TRAYS AND NOT TOWARDS THE
POWER SUPPLY. ALL INTERNAL CABLES SHOULD BE PLACED AT LEAST ONE INCH
ABOVE THE CIRCUIT BOARD, USE CABLE TIES IF NECESSARY.
3.1 Mounting one Jaz drive only
♦ Disconnect all cables including power from the back of the V1.
♦ Set the SCSI ID of the Jaz to 4, usually this is the Iomega factory default for the Jaz drive.
Refer to the Jaz manual to make sure the SCSI ID is set correctly.

The following procedure should be repeated for each Jaz drive mounted on the V1:
♦ Install the Jaz drive in the 3 1/2 to 5 1/4 bracket adapter supplied with the Jaz drive according to
the instruction supplied with the Jaz drive.
♦ Install the Jaz drive on the top V1 tray.
♦ Connect one of the internal free 50pin IDC connector to the Jaz Drive.
♦ Connect the power connector to the Jaz.
♦ Disconnect the SCSI ribbon cable from the main board (near the power supply) and connect
the end of this cable to the SCSI terminator supplied with the Jaz drive. This means that the
50pin IDC connector is now connected to the terminator and not to the V1 main board.
♦ Connect a SCSI cable from your computer to the Centronics 50 connector located on the back of
the V1.
♦ Connect the power cable, turn ON the V1 then turn ON your computer.
♦ Install the Jaz Tools software supplied with the Jaz on your computer
♦ Run Jaz tools, select Drive Options, set the drive to “No” Write verification and set the sleep
time to 30 minutes, then hit the button labeled “SET”.
♦ Quit the Jaz tools, turn OFF the computer and the V1.
♦ Remove the SCSI terminator from the end of the 50pin ribbon IDC cable and connect it back to
the V1 main board pin 1 (red mark on the cable) should be to your right if you are looking at the
front of the V1 (pin closer to the power supply).
♦ Connect the termination supplied with the V1 on the rear external SCSI port, switch ON the V1
and execute a Format command followed by an Initialize command.
3.2 Mounting two Jaz drives
♦ Disconnect all cables including power from the back of the V1.
♦ Repeat the procedure A. for each of the drives separately, and use SCSI ID4 for one and SCSI
ID3 for the other.
♦ Mount Jaz ID3 on the bottom V1 tray.
♦ Mount Jaz ID4 on the top V1 tray.
♦ Connect SCSI and power to both drives.
♦ Make sure you connect the end of the 50pin IDC to the V1 main board.
