Preface

This manual contains information for users of the Seagate®
Barracuda 9LP SCSI disc drives. It provides suppor t services,
performance speci fications, and initial setup information. Addi­tional information is available in the

Manual

(part number 77767517). Contact your Seagate sales

representative if you need to order this publ ication.

Electrostatic discharge protection

Caution.

All drive electronic assemblies 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 capacitors, may be damaged or degraded
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 (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.

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

Barracuda 9LP Product

2 Barracuda 9LP Installation Guide, Rev. E

• 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 syst 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 prac ti ces 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 removi ng 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 ver tically, pay special attention to the top where tem­peratures ar e usually highest.

Use forced-air ventilation when bench-testing the
drive to ensur e proper cooling of drive com ponents.

Barracuda 9LP Installation Guide, Rev. E 3

• Follow the precautions listed above in “Electrostatic 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 boards by personnel not performing depot
repair will damage components and may void the warranty.

• Do not remove the head and di sc assembly (HDA) from the
drive. 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 reasonabl e 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
acceptability in obtai ning 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 provi sion
for overcurrent protection on drive SELV supply vo ltages.

This unit is a component par t 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

Regulatory agency compliance

Electromagnetic susceptibility

As a component assembly, the drive is not required to meet any
susceptibility performance requirements. It is the responsib ility of
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
Tables 2a, 2b, and 2c, DC power requirements.

Electromagnetic compliance

Seagate uses an independent laboratory to confirm compliance
to the directives/standard(s) for CE Marki ng 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 lo ppy disc drive

• 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
shall confirm EMC compliance and provide CE Marking and C­Tick Marking for their prod uct.

General description

Barracuda 9LP SCSI disc drives are high-speed, random-access
digital-data storage devices.

The drive is a component for installation in an enclosure
designed for the drive. This is often a rack within the system or
an external enclosur e desi gned to house one or more di sc driv es
or other peripheral units. In either case, the disc drive must
receive adequate cooling (refer to “Providing adequate cool ing”)
and it must be sufficiently grounded and shielded from emis­sions. The

77767517) contains guidelines for a properly designed

enclosure.
