Preface
This manual contains information for users of the Seagate®
Cheetah 9LP SCSI dis c dri ves. It provides support services, per-
formance specifications, and initial setup information. Additional
information is available in the
number 83 329240). Contac t your Se agate sales representati ve if
you need to order this publication.
Electrostatic discharge protection
Caution.
All drive electronic assemblies are sensitive to static electricity,
due to the electrostatically sensitive devices used within the
drive cir cuitry. Although some devices such as metal- oxide semi-
conductors are extremely sensitive, all semiconductors, as well
as some resistor s and capacitors, may be dama ged or degraded
by exposure to static electricity.
Electrost ati c damage to electronic devices may be caused by t he
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.
Removal of circuit boards by personnel not performing depot repair will damage components and may
void the warranty.

• Turn off the power before removing or installing the DC power
cable.
• Do not remov e any circuit boards from the drive .
• Never use an ohmmeter on any circuit boards.
• When installing the dri ve on a carrier or t ray, discharge the carrier or tray pr io r to ins e rting it int o th e system.
Important safety information and precautions
Caution.
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, poss ibly 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 uni t.
• Use caution when troubleshooting a unit that has voltages
present. Tur n 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
Use forced-air ventilation when bench-testing the
drive to ensure proper cooling of drive components.

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 war ranty.
• 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 repairable. 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 designed to be installed and operated in accordance with UL1950, EN60950, CAN/CSA C22.2
950-M95, 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 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 requirements is the provision for overcurrent protection on drive SELV supply vol tages.
4 Cheetah 9LP Installation Guide, Rev. B
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 Department to assist the subsystem
designer.
Wichtige Sicherheitshinweise
Vorsicht.
Fremdbelüftung vorzusehen, um eine ausreichende Kühlung der
Laufwerkkomponenten sicher zustellen.
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 Risiko behaftet ist.
Die Warn- und Vorsichtshinweise sind nicht allumfassend! Es ist
uns einfach nicht möglich, alle Wartungsmethoden oder die
ev entuellen 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 gewähl te Verf ahren weder Ihre
persönliche Sicherheit noch die Leistung der Einheit gefährdet.
Beim Testen des Laufwerks auf dem Prüftisch ist
