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 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 there a differ ence between 10,000 RPM an d 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 due to increased 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) requirements.
Note. Please contact Seagate technical support services or
your distributor’s technical support if you have questions.

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 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 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, discharge the
carrier 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 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.
4 Cheetah 9 Installation Guide, Rev. B
• 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-
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 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 voltages.
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 through 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 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 contains guidelines for a properly designed enclosure.
