Viper 200® Ultrium tape drive. The
Viper 200 is a high-performance eight-channel Ultrium tape
drive that uses ½-inch Ultrium tape cartridges with a native
capacity of up to 100 Gbytes (200 Gbytes assuming 2:1 data
compression). It supports Read While Write (RWW) and
provides intelligent hardware data compression as well as
cartridge soft load. It comes with an ULTRA 2 WIDE SCSI
LVD (LVD), an Ultra Wide SCSI HVD (HVD) or a Fibre
Channel LC Optical (FC) interface and a library RS-422 serial
interface.

The Viper 200 design is well suited for mid-range to high-end
servers, mainframe systems, and tape library automation
systems.

The internal Viper 200 is designed to fit in a 5¼-inch full­height drive bay. The external drive is a standalone unit with
built-in power supply. The following Viper 200 models are
covered in this manual:

Unpacking and Inspection

Although drives are inspected and carefully packaged at the
factory, damage may occur during shipping. Follow these
steps for unpacking the drive.

1. Visually inspect the shipping containers and notify your

carrier immediately of any damage.

2. Place shipping containers on a flat, clean, stable surface;

then carefully remove and verify the contents against the
packing list. If parts are missing or the equipment is
damaged, notify your Seagate representative.

3. Save the containers and packing materials in case you

ever have to reship the drive.

Viper 200 Installation Manual 7

Installing an internal HVD or LVD Viper 200

This section describes the steps necessary to install an
internal Viper 200 drive with an Ultra 2 Wide SCSI LVD or
Ultra Wide SCSI HVD interface. For instructions on installing
a Fibre Channel drive, see page 15. For instructions on
installing an external HVD or LVD drive, see page 23.

Before you begin

The following guidelines and cautions apply to handling and
installing internal tape drives. Keep them in mind as you
install the drive.

• Determine if the drive is an FC, HVD or an LVD model.

Install an HVD drive only in an HVD environment, and an
LVD model only in an LVD environment. Do not mix HVD
and LVD devices. Look at the label above the drive’s
connector to determine if the drive is an FC, HVD or an
LVD model:

LVD label:

HVD label:

FC label:

Fibre Channel

Caution. Plugging an HVD drive into an LVD bus or vice

versa will make the entire bus non-functional and
may permanently damage the drive or other
SCSI devices on the bus.

• Because the Viper 200 drive can transmit data at up to 80

Mbytes/second, it is recommended that a maximum of
two Vipers be connected to one SCSI host adapter.

• Internal drives contain some exposed components that

are sensitive to static electricity. To reduce the possibility
of damage from static discharge, the drives are shipped
in a protective antistatic bag. Do not remove the drive
from the antistatic bag until you are ready to install it.

• Before you remove the drive from the antistatic bag,

touch a metal or grounded surface to discharge any static
electricity buildup from your body.

8 Viper 200 Installation Manual

• Always lay the drive either on top of the antistatic bag or

place it inside of the bag to reduce the chance of damage
from static discharge.

Configuring an internal HVD or LVD drive

Before you install the tape drive in your computer, you may
need to configure the drive’s SCSI ID and other drive
features. Jumpers located on the back of the drive (near the
left edge of the drive) are used to configure the SCSI ID and
to enable termination power.

Default settings

The default drive settings for the Viper 200 are listed below:

• SCSI ID: 6

• Termination Power: disabled.

If these default settings are appropriate for your needs, skip
ahead to “Mounting an internal HVD or LVD drive” on page

10.

Jumper settings

Configuration jumpers on the back of the drive control the
drive’s SCSI ID and SCSI terminator power. The jumpers can
also be used for remote SCSI address selection. Figure 1 on
the following page shows the locations of the jumper blocks
for the internal Viper 200.

SCSI Address Selection (pins 1 through 8)

You can select the SCSI address used by the drive by
placing the appropriate jumpers on pin-pairs 1-2 through
7-8, as shown in Figure 1.

Note: Each SCSI device on a bus must have a unique SCSI

ID. The SCSI controller or host adapter generally uses
ID 7. In some systems, the boot drive uses ID 0 or ID 1.

Terminator power (pins 11 and 12)

Internal HVD and LVD Viper 200 drives are shipped with
terminator power disabled, as shown in Figure 1. You can
enable terminator power, if necessary, by placing a jumper
across pins 11 and 12.

Note: The internal Viper 200 does not provide SCSI

termination. Thus, a terminator must be installed on
the drive if it is the last device in a SCSI chain. See
“SCSI termination” on page 13 for more information.

10 Viper 200 Installation Manual

Mounting an internal HVD or LVD drive

You can mount the internal Viper 200 either horizontally or
vertically with the drives left side facing up (see Figure 2). If a
drive is mounted vertically, the left side of the drive must face
up and the side of the drive should be within 5 degrees of
horizontal. If a drive is mounted horizontally, the base of the
drive must be within 15 degrees of horizontal and the PCB
side of the drive must face down.

YES YES NO NO

Figure 2. Acceptable mounting orientations for the
internal Viper 200

Mount the drive in a 5.25-inch, full-height drive bay and
secure it using two M3.0 metric screws on each side of the
drive. The locations of screw holes are shown in Figure 3 on
the following page. Do not use screws longer than 5 mm or
you may damage the drive.

Installing an internal Fibre Channel Viper 200

This section describes the steps necessary to install an
internal Viper 200 with a Fibre Channel LC Optical (FC)
interface. For instructions on installing a drive with an Ultra 2
Wide SCSI LVD or Ultra Wide SCSI HVD interface, see page

7. For instructions on installing an external HVD or LVD drive,
see page 23.

Before you begin

The following guidelines and cautions apply to handling and
installing internal tape drives. Keep them in mind as you
install the drive.

• Make sure your drive is an FC model. Install an FC model
only in a Fibre Channel environment. Look at the label
above the drive’s connector to determine if the drive is an
FC, HVD or an LVD model:

LVD label:

HVD label:

FC label:

Fibre Channel

• The Viper 200 drive can transmit data at an
instantaneous rate of 106.25 Mbytes/second and a
sustained rate of 80 Mbytes/second. In a Fibre Channel
loop environment, the maximum number of drives that
can be used simultaneously depends on the bandwidth of
the loop.

• Internal drives contain some exposed components that
are sensitive to static electricity. To reduce the possibility
of damage from static discharge, the drives are shipped
in a protective antistatic bag. Do not remove the drive
from the antistatic bag until you are ready to install it.

• Before you remove the drive from the antistatic bag,
touch a metal or grounded surface to discharge any static
electricity buildup from your body.

16 Viper 200 Installation Manual

• Always lay the drive either on top of the antistatic bag or
place it inside of the bag to reduce the chance of damage
from static discharge.

Configuring an internal Fibre Channel drive

Before you install the tape drive in your computer, you may
need to configure the drive’s hard-assigned loop identifier
and other drive features. Jumpers located on the back of the
drive (see Figure 7) are used to configure the ID.

acquire during the LIHA (hard address) phase of the Loop
Initialization Process (LIP). The jumpers can also be used for
remote ID selection. Figure 8 shows the location of the
assigned loop identifier jumper pins on the Viper 200 FC
drive.

Figure 8. Assigned loop identifier jumper pins for the
internal FC Viper 200

You can select the hard ID used by the drive by placing
jumpers on the appropriate assigned loop identifier jumper
pins. The seven sets of jumpers represent seven binary
digits, with the lowest binary weight (2^0) on the left (pins 13-

14) and the highest binary weight (2^6) on the right (pins 1-

2). If a jumper is placed on a set of pins (ON), the bit is set as

a “1.” If no jumper is on a set of pins, the bit is set as “0.”

The assigned loop identifier can be set from 0 to 125 (7Eh).
The Viper 200 FC is shipped with no jumpers in place (an ID
of 0000000).

The table below illustrates the system used for ID selection.
“ON” indicates a jumper installed on the pins indicated. Blank
cells indicate pins without a jumper installed.
