Preface

This manual contains information for users of the Seagate® ST423451 Elite 23 SCSI disc drives. It provides support services, performance specifications, and initial setup inform ation. Additional information is available in the (part number 83329140). Contact your Seagate sales representative if you need to order this publication.

Electrostatic disch arge protecti 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 the 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 installin g the DC power

cable.

• Do not remove any circuit boards from the drive.

• Never use an ohmmeter on any circuit boards.

• When installing th e drive on a carrier or t ray, discharge the

carrier or tray prior to inserting it into the system.

Important safety inform ati on and precau tion s

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 w hen the drive is mounted in an equipment rack or cabinet. When units are stacked vertically, pay special attention to the top where temperatures are usually highest.

Elite 23 Installation Guide, Rev. A 3

• 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.

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

• Do not attempt to disassemble the HDA. It is n ot 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 certi fy component assemblies, such as the Elite disc drive, based on their final acceptability in the end-use product. The subsystem designers are responsible for meeting these conditions of acceptability 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 protection on drive SELV supply volta ges.

This unit is a component part and as such is not meant to comply with FCC or similar national requirements as a stand-alone unit. Engineering radiated emissions test results are available

4 Elite 23 Installation Guide, Rev. A through the Seagate Safety Department to assist the subsystem

designer.

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.

Beachten Sie in jedem Fall die folgenden Warn-und Vorsichtshinweise:

Elite 23 Installation Guide, Rev. A 5

• 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 In stallations-und Entfernungsarbeiten beginnen.

• Wenn das Laufwerk in einem Einbaugestell oder Gehäuse

montiert ist, sorgen Sie dafür, daß die Temperatur im Inneren des Gestells oder Gehäuses die für das Laufwerk vorgegebenen Grenzwerte nicht übersteigt. Wenn Einheiten vertikal übereinander betestigt werden, achten Sie besonders auf den oberen Stapelbereich, da dort die Temperatur gewöhnlich am höchsten ist.
