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 the 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.

Scorpion 40 Installation Manual, Rev. A 3

Introduction

This installation manual summarizes the installation and

operation of Seagate®Scorpion 40 DDS-4 drives.

Note: DDS tape drives are sometimes referred to as “DAT”

drives. However, only the former term is used in this

manual.

The Scorpion 40 uses DDS-4 tape cartridges with a native

capacity of 20 Gbytes (40 Gbytes with 2:1 data

compression). It can also read and write older tapes using

DDS-1, DDS-2 and DDS-3 tape formats. Data compression is

supported for all these formats.

The Scorpion 40 supports the following SCSI interfaces:

•68-pin Ultra2 SCSI (LVD)

•68-pin SCSI Wide (single-ended)

•50-pin SCSI-2 (requires 68- to 50-pin single-ended

adapter such as Seagate PN 10006520-001)

Note: The Scorpion 40 will not work in a SCSI-1

environment.

The following Scorpion 40 models are covered in this manual:

Drive model number

Form factor

STD1401LW

3.5-inch internal drive

STD2401LW

5.25-inch internal drive

STD6401LW

External drive

Note. Additional or updated information on these drives may be

available on Seagate’s web site at www.seagate.com.

If you have purchased an external Scorpion 40, please turn to

page 15 for installation instructions. If you have purchased an

internal drive, continue to the next page.

4 Scorpion 40 Installation Manual, Rev. A

Installing an internal Scorpion 40

Before you begin

!Caution. Observe the following precautions to avoid

electrostatic damage to the internal drive during

installation.

•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 the drive down, lay it on top of the

antistatic bag or place it inside the bag.

Installation Overview

Internal drive installation involves three main steps:

1. Configuring the drive

2. Mounting the drive

3. Connecting the power and interface cables

Note: Internal Scorpion 40 drives come in different

configurations for mounting in 3.5-inch and 5.25-inch

drive bays. Drives configured for 5.25-inch bays are

identical to those used for 3.5-inch bays, but come

with mounting brackets and a wider face plate.

Installation procedures are the same for both drive

configurations.

Scorpion 40 Installation Manual, Rev. A 5

Configuring an internal Scorpion 40

Before you install the tape drive in your computer, you may

need to configure the drive’s SCSI ID or other drive features.

Jumpers located on the back of the drive (between the SCSI

interface and power connectors) are used to configure the

SCSI ID, parity checking, and termination power. Other drive

features are set using a bank of dip-switches on the

underside of the drive.

Default settings

The default drive settings for the Scorpion 40 are listed

below:

•SCSI ID: 6

•Media Recognition System (MRS) checking: enabled.

•Parity checking: enabled.

•Data compression: enabled.

•Power-on self-test diagnostics: enabled.

•Host operating system: Windows 95/98/NT/2000

•SCSI interface compatibility: Wide SCSI supported.

If these default settings are appropriate for your needs, skip

ahead to “Mounting an internal Scorpion 40” on page 10.

Jumper settings

Configuration jumpers on the back of the drive are used to

control the drive’s SCSI ID, parity checking, 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

Scorpion 40.

SCSI Address Selection (pins 1 through 8)

You can select the SCSI address used by the drive by

placing the appropriate jumpers on pins pairs 1-2 through

7-8, as shown in Figure 1. The SCSI address can also be

selected remotely by connecting a SCSI address-selection

switch to pins 1 through 8.

Scorpion 40 Installation Manual, Rev. A 7

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.

Parity checking (pins 9 and 10)

If a jumper is installed on pins 9 and 10 (the default setting),

parity checking is enabled. If no jumper is installed, parity

checking is disabled, but parity is still generated by the drive.

Terminator power (pins 11 and 12)

Internal Scorpion 40 drives are shipped with terminator power

disabled (no jumper across pins 11 and 12, as shown in

Figure 1). You can enable terminator power, if necessary, by

placing a jumper across pins 11 and 12.

Note: The internal Scorpion 40 does

not

provide SCSI

termination, and therefore should not be installed as

the last device in a SCSI chain. See “SCSI

termination” on page 13 for more information.

If the terminator power jumper is installed, be careful not to

short the TERMPWR signal to ground. In the event of a

short, terminator power to the bus will be interrupted. After

the short is removed, a fuse in the drive will automatically

reset, restoring terminator power.

Dip-switch settings

Figure 2 on the following page shows the location of dip

switches on the

underside

of the Scorpion 40. Each of these

switches is described in detail on subsequent pages.

If you change a dip switch, the new setting will not take effect

until the drive is turned off and then on again.
