Preface

This manual contains information for users of the Seagate®
Barracuda 18LP SCSI disc drives. It provides support services,
performance specifications, and initial setup information. Addi­tional information is available in the

Note.

If any differences exist between specification values in
this guide and the product manual , the product manual
values are t he authoritative values.

Electrostatic discharge protection

Caution.

All drive electronic assembli es are sensit ive to static electricity,
due to the electrostatically sensitive devices used within the
drive circuitry. Although some de vices such as metal-oxide semi­conductors are extremely sensitive, all semiconductors, as well
as some resistors and capacitors, may be damaged or deg raded
by ex posure to static electricity.

Electrost atic damage t o electroni c 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 exposed. Connect yourse lf to ground with a wrist
strap (Seagate part number 12263496). Connection may be
made to any grounded metal assembly. As a general rule,

Removal of circuit boards by personnel not perfor m­ing depot repair will damage components and may
void the war ranty.

Barracuda 18LP Product

2 Barra cuda 18LP Installation Guide, Rev. B

remember that you and the drive electronics must all be
grounded to avoid potentially damaging static di scharges.

• Turn off the power before removing or installing the DC power
cable.

• Do not remove any circuit boards from the drive.

• Never use an ohm meter on any cir cuit boards.

• When installing th e drive on a carrier or t ra y, discharge the car-

rier or tray pr io r to ins e rtin g 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 elimi nate the risk of personal injury. The warnings
point out conditions or practices that may endanger you or oth­ers. The cautions point out conditions or pr actices that may dam ­age the unit, poss ibly making it unsafe f or use.

Always observe the following warnings and precautions:

• Follow all cautions and war nings 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 re mo ving 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 ensur e proper cooling of drive components.

stacked vertically, pay special attention to the top where tem­peratures are usually highest.

• Follow the precautions listed above in “Electrost atic discharge
protection.”

• Do not remove any circuit boards from the drive. Retur n 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 remove the head and disc assembly (HDA) from the
drive. Return the entire drive for depot repair if the HDA is
defective.

• Do not atte mpt to disassemble the HDA. It is not field repair­able. I f 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 Barracuda disc drive, based on their
final acceptability in the end-use product. The subsystem
designers are responsible for meeting these conditions of
acceptabil ity in obtaining safety-regulato ry agency compliance in
their end-use products and for certifying where required by law.
A necessary part of meeting safety requirements is the provi sion
for overcurrent protection on drive SELV supply vo lt ages.

This unit is a component part and as such is not meant to com-

ply with FCC or simil ar national r equirements as a stand-alone
unit. Engineering radiated emissions test results are available
through the Seagate Safety Department to assist the subsystem
designer.
