Preface

This manual contains information for users of the Seagate®
Barracuda 4XL SCSI disc drives. It provides support services,
performance specifications, and initial setup information. Addi­tional information is available in the

Manual

(part number 77767500). Contact your Seagate sales

representative if you need to order this publication.

Electrostatic discharge p rotecti on

Caution. Removal of circuit boards by personnel not perform-

ing depot repair will damage components and may

void the warranty.
All drive electronic assemblies are sensitive to static electricity,
due to the electrostatically sensitive devices used within the

drive circuitry. Although some devices such as metal-oxide semi­conductors are extremely sensitive, all semiconductors, as well
as some resistors and capacitors, may be damaged or degraded
by exposure to static electricity.

Electrostatic damage to electronic devices may be caused by th e
direct discharge of a charged conductor or by exposure to the
static fields surrounding charged objects. To avoid damaging
drive electronic assemblies, observe the following precautions
when installing or servicing the drive:

• Ground yourself to the drive whenever the drive electronics

are or will be exposed. Connect yourself to ground with a wrist
strap (Seagate part number 12263496). Connection may be
made to any grounded metal assembly. As a general rule,
remember that you and the drive electronics must all be
grounded to avoid potentially damaging static discharges.

• Turn off the power before removing or installing the DC power

cable.

• Do not remove any circuit boards from the drive.

• Never use an ohmmeter on any circuit boards.

• When installing the drive on a carrier or tray, disc harge the car-

rier or tray prior to inserting it into the system.

Important safety inform ati on and precau tions

Caution. Use forced-air ventilation when bench-testing the

drive to ensure proper cooling of drive components.
Use proper safety techniques for safe, reliable operation of this

unit.
The procedures in this manual and labels on the unit contain

warnings and cautions that must be carefully read and followed
to minimize or eliminate the risk of personal injury. The warnings
point out conditions or practices that may endanger you or oth­ers. The cautions point out conditions or practices that may dam­age the unit, possibly making it unsafe for use.

Always observe the following warnings and precautions:

• Follow all cautions and warnings in the procedures.

• Use sound safety practices when operating, installing, or

removing the unit.

• Use caution when troubleshooting a unit that has voltages

present. Turn off power to the unit before removing it.

• Ensure that the internal temperature of the rack or cabinet

does not exceed the limits defined for the drive when the drive
is mounted in an equipment rack or cabinet. When units are

Barracuda 4XL Installation Guide, Rev. B 3

stacked vertically, pay special attention to the top where tem­peratures are usually highest.

• Follow the precautions listed above in “Electrostatic discharge

protection.”

• Do not remove any circuit boards from the drive. Return the

entire drive for depot repair if any circuit board is defective.
Removal of circuit boards by personnel not performing depot
repair will damage components and may void the warranty.

• Do not remove the head and disc assembly (HDA) from the

drive. Return the entire drive for depot repair if the HDA is
defective.

• Do not attempt to disassemble the HDA. It is not field repair-

able. If the sealed HDA is opened by personnel not performing
depot repair, this will damage components and void the
warranty.

As a component, this drive is d esigned to be installe d and op er­ated in accordance with UL1950, EN60950, CSA C22.2 950­M89, and VDE0805.

Seagate takes all reasonable steps to ensure that its products
are certifiable to currently accepted standards. Typical applica­tions of these disc drives include customer packaging and sub­system design. Safety agencies conditionally certify component
assemblies, such as the Barracuda disc drive, based on their
final acceptability in the end-use product. The subsystem
designers are responsible for meeting these conditions of
accepta b il ity in obtaining safety-regulatory agency compliance in
their end-use products and for certifying where required by law.
A necessary part of meeting safety requirements is the provision
for overcurrent protect ion on drive SELV supply voltages.

4 Barracuda 4XL Installation Guide, Rev. B
This unit is a component part and as such is not meant to com-

ply with FCC or similar nati onal requirements as a stand-alone
unit. Engineering radiated emissions test results are available
through the Seagate Safety Department to assist the subsystem
designer.

Wichtige Sich erh eitsh in wei se

Vorsicht. Beim Testen des Laufwerks auf dem Prüftisch ist

Fremdbelüftung vorzusehen, um eine ausreichende Kühlung der
Laufwerkkomponenten sicherzustellen.

Verwenden Sie geeignete Sicherheits- um den sicheren, zuver­lässigen Betrieb dieser Einheit zu gewährlei sten.

Die Verfahren in diesem Handbuch und die Aufkleber auf dem
Gerät enthalten Warn- und Vorsichtshinweise. Diese Hinweise
sind sorgfältig durchzulesen und zu beachten, um das Risiko
von Verletzungen auf ein Mindestmaß zu beschränken oder
ganz zu vermeiden. Die Warnhinweise machen auf Situationen
oder Praktiken aufmerksam, die Sie oder andere gefährden
könnten. Die Vorsichtshinweise machen auf Situationen oder
Praktiken aufmerksam, die Einheit beschädigen können, so daß
deren Gebrauch mit Risiko behaftet ist.

Die Warn- und Vorsichtshinweise sind nicht allumfassend! Es ist
uns einfach nicht möglich, alle Wartungsmethoden oder die
eventuellen Risiken jeder Methode zu kennen, zu beurteilen und
Sie entsprechend zu beraten. Aus diesem Grund haben wir auf
eine derartige umfassende Beurteilung verzichtet. Falls Sie ein
hier nicht beschriebenes Verfahren oder Werkzeug verwenden,
stellen Sie zuerst sicher, daß das gewählte Verfahren weder Ihre
persönliche Sicherheit noch die Leistung der Einheit gefährdet.

Barracuda 4XL Installation Guide, Rev. B 5
Beachten Sie in jedem Fall die folgenden Warn-und Vorsicht-

shinweise:

• Beachten Sie alle Warn- und Vorsichtshinweise in diesem

Handbuch.

• Treffen Sie beim Betrieb, bei der Installation oder bei der

Entfernung der Einheit angemessene Sicherheitsvorkehrun­gen.

• Wenn eine Einheit unter Spannung steht, gehen Sie bei der

Fehlerdiagnose besonders vorsichtig vor. Schalten Sie die
Einheit aus, bevor Sie mit den Installations-und Entfernungsar­beiten beginnen.

• Wenn das Laufwerk in einem Einbaugestell oder Gehäuse

General description

Barracuda 4XL SCSI disc drives are high-speed, random-access
digital-data storage devices.

The drive i s a componen t for installation in an enclos ure
designed for the drive. This is often a rack within the system or
an external enclosure designed to house one or more disc d rives
or other peripheral units. In either case, the disc drive must
receive adequate cooling (refer to “Providing adequate cooling”)
and it must be sufficiently grounded and shielded from emis­sions. The
