Electrostatic discharge protection

Cauti on.

All drive electronic assemblies are sensitive to static electricity,
due to the electrostatically sensitive devices used within the
drive circui try. Althou gh some devices such as metal-oxide semi ­conductors are extremely sensitive, all semiconductors, as well
as some resistors and capacitors, ma y be damaged or degra ded
by exposure to static electricity.

Removal of circuit boards by personnel not perform­ing depot repair will damage components and may
void the warranty.

Elect rost atic damage t o electr onic de vices may be caus ed 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.

2 Cheetah 18 I nstallation Guide, Rev. A

• 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 inst alli ng the drive on a carrier or t ra y, discharge the car-

rie r o r tray pr io r to ins e rting it into th e syst e m .

Importan t safety information and precau tions

Caution.

Use forced-air ventilation when bench-testing the
drive to ensure prop er cooling of driv e com ponents.

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 minim ize or eliminat e the ris k of pers onal 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 uni t, possibly making it unsafe for use.

Always observe the following warnings and precautions:

• Follow al l cautions and war nings in t he 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 uni t befo re 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

Cheetah 18 Installation Guide, Re v. A 3

stacked vertically, pay special attention to the top where tem­peratures are usual ly 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
repai r will damage compo nents and may void the w arranty.

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

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

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

abl e. If t he sealed HDA is opened by personn el not performing
depot repair, this will damage components and void the
warranty.

As a component, this drive is designed to be installed and oper­ated in accordance with UL1950, EN60950, CAN/CSA C22.2
950-95, 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 cer tify component
assemblies, such as the Cheetah 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 requirement s is the provision for overcur­rent protection on drive SELV supply voltages.

4 Cheetah 18 I nstallation Guide, Rev. A
This unit is a component part and as such is not meant to com-

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

Wichtige Sicherheitshinweise

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 gewährleisten.

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 Risi ko behaft et ist.

Die Warn- und Vor sichtshinweise sind nicht allumfassend! Es ist
uns einfach nicht möglich, alle Wartungsmethoden oder die
eventuellen Risiken j eder Methode zu kennen, zu beur teilen 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 gewä hlt e Verfahren weder Ihr e
persönliche Sicherheit noch die Leistung der Einheit gefährdet.

Cheetah 18 Installation Guide, Re v. A 5
Beachten Sie in jedem Fall die folgenden Warn-und Vorsicht-
