Preface
This manual contains information for users of the Seagate®
Cheetah 9 SCSI disc drives. It provides support services, performance specifications, and initial setup information. Additional
information is available in the
Cheetah 9 Product Manual
(part
number 83329170). Contact your Seagate sales representative
if you need to order this publication.
Attention. This high performance Cheetah disc drive MUST
have proper power and cooling considerations for
reliable operation.
Why is ther e a differ ence between 10,000 RPM and 7,200 RPM
disc drives?
• Cheetah disc drives spinning at 10,000 RPM will dissipate
more heat than 7,200 RPM class disc drives (typical power
dissipation is 22.5 watts).
• The increased heat is primarily d ue to incre ased motor power
dissipated inside the drive.
• The increase in heat dissipation requires that the Cheetah
10,000 RPM disc drives receive more cooling consideration
than 7,200 RPM class disc drives.
• Proper consideration of enhanced cooling by conduction (heat
transfer thru material) ca n reduce the convection cooling (heat
transfer by air motion) requirem ents.
Note. Please contact Seagate technical support services or
your distributor ’s technical support if you have questions.

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 elect ricity.
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 dam aging
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 cir cui t boards.
• When installing the drive on a carrier or tray, discharge the
carrier or tray prior to inserting it into the system.

Impo rtant 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 follo wed
to minimize or eliminate the risk of personal injury. The warnings
point out conditio ns 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 pre cautions:
• 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 limit s 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.
• Follow the precautions listed above in “Electr ostatic discharge
prote ction.”
• 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 d amage components and may void the warranty.
4 Cheetah 9 Installation Guide, Rev. B
• Do not separate the he ad and disc as sembl y (HDA) from t he
PCB. 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 i s designed to be install ed an d operated 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 de sign. Safety agencies conditionally certi fy 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 requir ements is the provision for overc urrent prot ection on drive SELV supply voltages.
This unit is a component part and as such is not meant to comply
with FCC or similar national requirement s as a stand-alone unit.
Engineering radiated emissions test results are available
throu gh the Seagate Safety Department to assist the subsystem
designer.

General description
Cheetah 9 SCSI disc drives are high-speed, random-access digital-data storage devices.
The d rive is a componen t for installa tion 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 drives
or other peripher al units. In either case, the disc drive must
receive adequate cooling (refer t o “Pro viding adequate cooling”)
and it must be sufficiently grounded and shielded from emissions. The
Cheetah 9 Product Manual
(part number 83329170)
contains guidelines for a properly designed enclosure.
