ST43400N/ND User’s Manual iii

Preface

This manual contains information for users of the Seagate ST43400N and

ST43400ND Elite disc drives employing the SCSI interface. It provides instal-

lation, operation, and maintenance information. This manual also lists the part

numbers for options and accessories available for these drives. Additional

information is available in the reference manual (publication 83327640).

Electrostatic discharge protection

Caution. Removal of circuit boards by personnel not performing depot repair

will damage components and may void the warranty.

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 surround-

ing charged objects. To avoid damaging drive electronic assemblies, ob-

serve 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 (refer to accessories

in Section 4 for part numbers). Connection may be made to any grounded

metal assembly. As a general rule, remember that you and the drive electron-

ics must all be grounded to avoid potentially damaging static discharges.

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

• Do not remove any circuit boards from the drive.

• Never use an ohmmeter on any circuit boards.
