Preface

This manual contains information for users of the Seagate®

Cheetah 18 SCSI disc drives. It provides support services, per-

formance specifications, and initial setup infor mation. Additional

infor mat ion i s availa ble in the

number 8332926 0). Contac t your Seagate sal es repres enta tiv e if

you need to order t his publication.

Electrostatic discharge protection

Caution.

All drive electronic assembli es are sensitive to static electricity,

due to the electrostatically sensitive devices used within the

drive cir cui try. Although some devices such as metal-oxide semi-

conductors are extremely sensitive, all semiconductors, as well

as some resi stors and capacit ors, may be damaged or deg raded

by exposure to static electricity.

Electrost 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 expos ed. Connect yourse lf to ground with a wrist
strap (Seagat e par t 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 war ranty.

• 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 th e drive on a carrier or t ra y, discharge the car­rier or tray pr io r to ins e rting it into th e sy st e m.

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 conditi ons 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 warnin gs 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. 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 t he drive
is mounted in an equipment rack or cabinet. When units are

drive to ensur e proper cooling of driv e com ponents.

Cheetah 18 Installation Guid e, Rev. A 3

stacked ver tically, pay special attention to the top where tem­peratures ar e 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 boar ds by personnel not performing depot
repair will damage components and may void the warranty.

• 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
950-95, 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 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 r equirements is the provision for overcur­rent protection on dr ive SELV supply voltages.

4 Cheetah 18 Instal lation Guide, Rev. A
This unit is a component par t and as such is not meant to com-

ply with FCC or simil ar 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.

As a component assembly, the drive is not required to meet any
susceptibility performance requirements. It is the responsi bility o f
those integrating the drive within their systems to perfor m those
tests required and design their system to ensure that equipment
operating in the same system as the drive or external to the sys­tem does not adversely affect the perfor mance of the drive. See
DC power requirements on page 18.

Electromagnetic compliance

Seagate uses an independent laboratory to confirm compliance
to the directives/standard(s) for CE Marking and C-Tick Marking .
The drive was tested in a repre sentative system for typical appli­cations. The selected system represents the most popular char­acteristics for test platforms. The sy stem configurations include:

• 486, P entium, and P owerPC microprocessors

• 3.5 -inch f loppy disc dri ve

• Keyboard

• Monitor/display

• Printer

• External modem

• Mouse

Although the test system with this Seagate model complies to
the directives/standard(s), we cannot guarantee that all systems
will comply. The computer manufacturer or system integrator

8 Cheetah 18 Instal lation Guide, Rev. A
shall confirm EMC compliance and provide CE Marking and C-

Tick Marking for their product.
