FCC notice
This equipment generates and uses radio frequency energy and, if not
installed and used in strict accordance with the manufacturer's instructions,
may cause interference to radio and television reception, which could void
the user's authority to operate the equipment. It has been tested and found
to comply with the limits for a Class B digital device pursuant to Part 15 of
FCC Rules, which are designed to provide reasonable protection against
such interference in a residential installation. However, there is no
guarantee that interference will not occur in a particular installation. If
interference does occur, try to correct it by taking one or more of the
following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the computer and the receiver.
• Connect the computer into an outlet on a circuit different from that to
which the receiver is connected.
• Consult your dealer or an experienced radio/television technician for help.
You may find the following booklet prepared by the Federal Communications
Commission helpful: How to Identify and Resolve Radio–TV Interference
Problems. This booklet (Stock No. 004-000-00345-4) is available from the
U.S. Government Printing Office, Washington, DC 20402. Further, this
equipment complies with the limits for Class B digital apparatus in
accordance with Canadian Radio Interference Regulations.
Cet appareil numérique de la classe B est conforme au Règlement sur
brouillage radioélectrique, C. R. C., ch. 1374.

Introduction
This manual contains information on how to install and
operate Seagate®digital audio tape (DAT) drives. This
manual covers DAT drives that support the DDS (digital data
storage), DDS-DC, DDS-2 and DDS-3 tape formats.
The following table identifies the Seagate DAT drive models
covered by this manual and the tape formats that they
support.

A-6 Seagate DAT Drive Installation Manual—English
Before you begin
!Caution. If you are installing an internal drive,
observe the following precautions to avoid damaging
the drive through electrostatic discharge.
• 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 grounded metal surface to discharge any static
electricity buildup from your body.
• Hold the drive only by its edges and avoid direct contact
with any electronic components.
• If you need to put down the drive, lay it on top of the
antistatic bag or place it inside the bag.
SCSI cables and connectors
These Seagate DAT drives can be connected to a standard,
single-ended SCSI or SCSI-2 interface. A 50-conductor flat
cable or a 25-signal twisted-pair cable may be used to
connect the drive to a SCSI host adapter. The cable should
not be longer than 6 meters (19.5 feet).
The internal DAT drive provides a 50-pin, dual-row single-
ended SCSI connector at the back of the drive.
The external DAT drive provides two 50-pin, shielded
connectors (ANSI Alternative 2) on the rear panel of the
drive. These connectors consist of two rows of ribbon
contacts spaced 2.16 mm (0.085 in) apart. Either connector
can be used as a SCSI IN or SCSI OUT connection.
Seagate DAT Drive Installation Manual—English A-7
Installing an internal DAT drive
Internal drive installation involves three main steps:
1. Configuring the drive
2. Mounting the drive
3. Connecting power and interface cables
➤ Note: Internal Seagate DAT drives come in two mounting
configurations. Drives configured for 5.25-inch bays are
identical to those designed for 3.5-inch bays except that
drive mounting brackets have been added on each side
of the drive. Installation procedures are the same for both
drive configurations.
Configuring an internal DAT drive
Before you install the tape drive in your computer, you may
need to set the drive’s SCSI ID or other drive features. Most
features are set using a bank of dip-switches on the
underside of the drive (see Figure 1 below). To control SCSI
termination and terminator power or to configure the drive for
remote SCSI address selection, use the jumpers on the back
of the drive (above the interface and power connectors).
➤ Note: The dip-switch and jumper configurations shown
here apply
only
to Seagate drives whose model numbers
begin with the letters “STD.” For older DAT drives, see
the Seagate web site (www.seagate.com) or contact
Seagate technical support, as described on page A-39.

Dip-switch settings
The default dip switch settings for Scorpion 4, 8, and 24 DAT
drives are listed below:
• SCSI ID 0
• The drive reads or writes both MRS and non-MRS
4-mm media.
• Parity checking is disabled.
• Data compression is enabled.
• Power-on self-test diagnostics are disabled.
The drive is shipped with SCSI termination disabled. If the
default settings are appropriate for your computer system
and
you do not need to enable SCSI termination for this
drive, skip ahead to “Mounting an internal DAT drive” on page
A-13.
Changing dip-switch settings
Figure 2 on the following page shows the location of dip
switches on the underside of a Seagate internal DAT drive.
Factory-default settings for each switch are also shown in
Figure 2. Each of these settings is described in detail on the
following pages.
➤ Note: Not all drives come with dip switches 9 and 10.
These switches are used to configure the drive for use
with UNIX operating systems, as described on page A-27
of this manual.
