Preface

This manual contains information for users of the Seagate® Cheetah 4LP SCSI disc drives. It provides s upp ort services, performance specifications, and initial setup information. Additional information is available in the number 83329120). 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 operatio n.

Why is there a difference 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 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) can 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 protection

Caution.

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.

• Tur n off the power before removing or installing the DC power cable.

• Do not remove any circuit board s 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.

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

Cheetah 4LP Installation Guide, Rev. B 3

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 ris k 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.

Use forced-air ventilation when bench-testing the drive to ensure proper cooling of drive components.

4 Cheetah 4LP 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 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, CSA C22.2 950M89, and VDE0805.

Seagate takes all reasonable ste ps 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 respons ible for meeting t hese conditions of acceptabi lity 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 compon ent part and as s uch i s no t meant t o c omply 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.
