Preface
This manual contains information for users of the Seagate®
Medalist Pro SCSI disc drives. It provides support services, per-
formance specifications, and initial setup information. Additional
information is available in the
Medalist Pro Product Manual (part
number 32661-001). Contact your Seagate sales representative
if you need to order this publication.
Handling precautions
• Disc drives are fragile. Do not drop or jar the drive. Use a
padded surface during installation to avoid damaging the
drive.
• Keep the drive in its antistatic bag until you are ready to
install it.
• Protect the drive from static discharge by making sure you
are well grounded before touching the drive. We recommend
wearing a grounded wrist strap (Seagate part number
12263496) throughout the installation process. Do not touch
the connectors or any part of the printed circuit board.
• Always handle the drive by its edges or frame.
• Do not apply pressure or attach labels to the circuit board or
the top of the drive.

Electrostatic discharge protection
Caution. Removal of circuit boards by personnel not perform-
ing 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 semi-
conductors 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 car-
rier or tray prior to inserting it into the system.

Medalist Pro Installation Guide, Rev. B 3
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 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 conditions or practices that may endanger you or oth-
ers. The cautions point out conditions or practices that may dam-
age the unit, possibly making it unsafe for use.
Always observe the following warnings 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 removing 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 tem-
peratures are usually highest.
• 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
repair will damage components and may void the warranty.

4 Medalist Pro Installation Guide, Rev. B
• 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 repair-
able. 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 oper-
ated in accordance with UL1950, EN60950, CSA C22.2 950-
M89, and VDE0805.
Seagate takes all reasonable steps to ensure that its products
are certifiable to currently accepted standards. Typical applica-
tions of these disc drives include customer packaging and sub-
system design. Safety agencies conditionally certify component
assemblies, such as the Medalist disc drive, based on their final
acceptability in the end-use product. The subsystem designers
are responsible for meeting these conditions of acceptability 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 overcur-
rent protection on drive SELV supply voltages.
This unit is a component part and as such is not meant to com-
ply with FCC or similar national requirements as a stand-alone
unit. Engineering radiated emissions test results are available
through the Seagate Safety Department to assist the subsystem
designer.

Wichtige Sicherheitshinweise
Vorsicht. Beim Testen des Laufwerks auf dem Prüftisch ist
Fremdbelüftung vorzusehen, um eine ausreichende Kühlung der
Laufwerkkomponenten sicherzustellen.
Verwenden Sie geeignete Sicherheits- um den sicheren, zuver-
lässigen Betrieb dieser Einheit zu gewährleisten.
Die Verfahren in diesem Handbuch und die Aufkleber auf dem
Gerät enthalten Warn- und Vorsichtshinweise. Diese Hinweise
sind sorgfältig durchzulesen und zu beachten, um das Risiko
von Verletzungen auf ein Mindestmaß zu beschränken oder
ganz zu vermeiden. Die Warnhinweise machen auf Situationen
oder Praktiken aufmerksam, die Sie oder andere gefährden
könnten. Die Vorsichtshinweise machen auf Situationen oder
Praktiken aufmerksam, die Einheit beschädigen können, so daß
deren Gebrauch mit Risiko behaftet ist.
Die Warn- und Vorsichtshinweise sind nicht allumfassend! Es ist
uns einfach nicht möglich, alle Wartungsmethoden oder die
eventuellen Risiken jeder Methode zu kennen, zu beurteilen und
Sie entsprechend zu beraten. Aus diesem Grund haben wir auf
eine derartige umfassende Beurteilung verzichtet. Falls Sie ein
hier nicht beschriebenes Verfahren oder Werkzeug verwenden,
stellen Sie zuerst sicher, daß das gewählte Verfahren weder Ihre
persönliche Sicherheit noch die Leistung der Einheit gefährdet.
Beachten Sie in jedem Fall die folgenden Warn-und Vorsicht-
shinweise:

General description
Medalist Pro 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 enclosure designed to house one or more disc drives
or other peripheral units. In either case, the disc drive must
receive adequate cooling (refer to “Providing adequate cooling”)
and it must be sufficiently grounded and shielded from emis-
sions. The
Medalist Pro Product Manual (part number 32661-
001) contains guidelines for a properly designed enclosure.
