Preface

This manual contains information for users of the Seagate®
Barr acuda 36 SCSI disc driv es. It pro vides support services, per ­formance specifications, and initial setup information. Additional
information is available in the

Barracuda 36 Product Manual

(part number 77767528). Contact your Seagate sales represen­tative if you need to order this publication.

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-ox ide semi­conductors are extremely sensitive, all semiconductors, as well
as some resisto rs and capacitors, may be damaged or degraded
by exposure to static electricity.

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

Electr ost 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 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 avoi d potentially damaging static discharges.

2 Barr acuda 36 Installation G uide, Re v. B

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

• Do not remove any circuit boards from the driv e.

• Never use an ohmmeter on any circuit boards.

• When inst alli ng the drive on a carrier or t ra y, disch arge the car -

rie r o r tray pr io r to ins e rting it into th e sy st e m.

Importan t safety information and precautions

Caution.

Use forced-air ventilation when bench-testing the
drive to ensure prop er cooling of driv e com ponents.

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 minim ize or eliminat e the risk of pers onal injury. The warnings
point out conditions or practices that may endanger you or oth­ers. The cautions point out conditions or pr actices that may dam­age the uni t, possibly making it unsafe for use.

Always observe the fo ll owing warnin gs 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 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
stacked vertically, pay special attention to the top where tem­peratures are usually highest.

Barracuda 36 Installation Guide, Rev. B 3

• 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
repai r 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 attempt to disassemble the HDA. It is not field repair­abl e. If the sealed HDA is opened b y personnel not per forming
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
acceptabilit y in obtaining saf ety-re gulatory agency com pliance in
their end-use products and for certifying where required by law.
A necessary part of meeting safety requirements is the provision
for overcurre nt pr otection on driv e 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
