 J2 Terminating the drive
 ------------------------
 ST19171N drives are terminated with permanently mounted IC active
 terminators. If you install one of these drives and it is not on the
 end of the SCSI bus, disable the terminators by removing the jumper
 from pins 15 and 16 of connector J2. If you install the drive on the
 end of the SCSI bus, enable termination by installing a jumper on
 pins 15 and 16 of connector J2.

SEAGATE  ST19171N/W/WD/WC/DC  INSTALLATION GUIDE 83329020 REV. A

 Preface
 -------
 This manual contains information for users of the Seagate ST19171
 Barracuda 9 SCSI disc drives. It provides support services,
 performance specifications, and initial setup information.


 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 metaloxide 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 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 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.

 - When installing the drive on a carrier or tray, discharge the
   static electricity from the carrier or tray prior to inserting it
   into the system.


 Important safety information and precautions
 --------------------------------------------
 Caution. Use forced-air ventilation when bench testing the drive to
 ensure proper cooling of drive components.

 Use proper safety and repair techniques for safe, reliable operation
 of this unit. Service should be done only by qualified persons.

 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 condi-
 tions or practices that may endanger you or others. The cautions
 point out conditions or practices that may damage the unit, possibly
 making it unsafe for use.

 Always observe the following warnings and precautions:

 - Perform all maintenance by following the procedures in this manual.

 - Follow all cautions and warnings in the procedures.

 - Use sound safety practices when operating or repairing the unit.

 - Use caution when troubleshooting a unit that has voltages present.
   Turn off power to the unit before servicing it.

 - Wear safety shoes when removing or replacing heavy parts.

 - 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.

 - Do not remove any circuit boards from the drive chassis. Return
   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 disc assembly (HDA) from the drive
   chassis. 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 compo-nents and void the warranty.

 As a component, this drive is designed to be installed and operated
 in accordance with UL1950, IEC950, EN60950, CSA C22.2 950, and
 VDE0805.

 Typical applications of these disc drives include customer packag-
 ing 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 accept-
 ability in obtaining 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 provision
 for overcurrent protection on drive 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 standalone unit.
 Engineering radiated emissions test results are available through
 the Seagate Safety Department to assist the subsystem designer.


 General description
 -------------------
 Barracuda 9 SCSI disc drives are high-speed, randomaccess 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
 enclosure designed to house one or more disc drives or other
 peripheral units. In either case, the disc drive must receive
 adequate cooling and it must be sufficiently grounded and
 shielded from emissions.
