Preface
This manual contains information for users of the Seagate®
ST446452 Elite 47 SCSI disc drives. It provides support ser-
vices, performance specifications, and initial setup information.
Additional information is available in the Elite 47 Product Manual
(part number 83329280). Contact your Seagate sales represen-
tative if you need to order this publication.
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.
2
Elite 47 Installation Guide, Rev. B
• 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.
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.”
Elite 47 Installation Guide, Rev. B

• 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.
• 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 Elite 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.

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

Regulatory agency compliance
Electromagnetic susceptibility
As a component assembly, the drive is not required to meet any
susceptibility performance requirements. It is the responsibility of
those integrating the drive within their systems to perform those
tests required and design their system to ensure that equipment
operating in the same system as the drive or external to the sys-
tem does not adversely affect the performance of the drive. See
Table 2, DC power requirements.
Electromagnetic compliance
Seagate uses an independent laboratory to confirm compliance
to the directives/standard(s) for CE Marking and C-Tick Marking.
The drive was tested in a representative system for typical appli-
cations. The selected system represents the most popular char-
acteristics for test platforms. The system configurations include:
• 486, Pentium, and PowerPC microprocessors
• 3.5-inch floppy 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 C-
Tick Marking for their product.

General description
Elite 47 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 Elite 47 Product Manual (part number 83329280)
contains guidelines for a properly designed enclosure.

2A –10% tolerance is permissible during initial start of the spin-
dle but must return to ±5% before reaching 5,357 r/min. The
±5% must be maintained after the drive signifies that its
power-up sequence has been completed and that the drive is
able to accept selection by the host initiator.
3See the +12V current profile in the Elite 47 Product Manual
(publication number 83329280).
4This condition occurs when the Motor Start option is enabled
and the drive has not yet received a Start Motor command.
5See “Conducted noise immunity” in the Elite 47 Product Man-
ual. The specified voltage tolerance is inclusive of ripple,
noise, and transient response.
6At power-up, the motor current regulator limits the +12V cur-
rent to an average value of less than 4.8A, although instanta-

neous peaks may exceed this value. These peaks should
measure 5 msec duration or less.
7Minimum current loading for each supply voltage is not less
than 4% of the maximum operating current shown.
8Use separate ground returns for +5V and +12V supplies.
9Where power is provided to multiple drives from a common
supply, carefully consider individual-drive power requirements.
Where multiple units are powered on simultaneously, be sure
the peak starting current is available to each device.

Initial setup information
The following topics are discussed in this section:
• SCSI ID jumpers
• Drive termination
• Terminator power
• Interface drivers and data path width notes
• Other applicable jumper options
• Providing adequate cooling
• Mounting the drive and connecting cables
• Formatting the drive
Elite 47 Installation Guide, Rev. B
19
SCSI ID jumpers
Each device on the SCSI chain must have a unique SCSI ID.
The host system’s SCSI controller usually uses the ID that has
the highest priority interrupt in the SCSI I/O system. This is
always ID7. ID0 is lowest priority in an 8-bit I/O system. ID8 is
lowest priority in a 16-bit I/O system. The lower priority SCSI IDs
are normally used for other SCSI devices such as this Elite disc
drive.
Note.
Most SCSI controllers (host adapters) allow you to skip a
SCSI ID. For example, you can have ID0, ID1, and ID3
(skipping ID2). Other controllers do not allow this so be
sure to refer to your system or controller user’s manual for
details about its requirements for proper SCSI device
installation.
Note.
This drive is a SCAM (SCSI Configured Auto Magically)
compliant drive. If the system into which you are installing
this drive requires SCAM compliant drives, you do not
need to be concerned about the drive ID jumper settings,
as the system automatically assigns your new drive the
ID it wants it to have. The system may or may not use the
existing drive ID jumper settings. Setting the drive ID
doesn’t hurt anything, but is not necessary in a SCAM
compliant system.
20
Elite 47 Installation Guide, Rev. B
Most Elite 47 disc drives are factory set with the SCSI ID set at
0. To change the SCSI ID, install jumpers on the appropriate pins
as shown in Figure 2.

Figure 2.
Setting the SCSI ID
If, after completing the installation process, the drive’s LED does
not show on/off activity when the host is trying to communicate
with the drive, a duplicate SCSI ID may be the problem. If this is
the case, change the ID so that each device on the SCSI chain
has its own unique ID. Also check your system or controller
Elite 47 Installation Guide, Rev. B
21
user’s manual to ensure that you have not violated its SCSI ID
numbering recommendations.
Drive termination
If you are installing a Elite 47 drive in a system that has other
SCSI devices installed, terminate only the end devices on the
SCSI chain. A SCSI device is any disc drive, scanner, tape
backup unit, or other piece of hardware connected to your sys-
tem using the SCSI bus.
The top example in Figure 3 shows an internal hard disc at one
end of the SCSI bus with the SCSI controller at the other end
(both are terminated). The bottom example shows two additional
SCSI devices connected externally. This means the SCSI con-
troller is no longer on the end of the SCSI chain and should not
be terminated.
Note.
Some controllers prefer to remain terminated even if they
are in the middle of the chain. Also, some controllers treat
the internal and external chains as separate logical
buses. This means you may need to terminate both the
first and last devices on both logical buses to achieve
proper termination. If necessary, refer to your system or
controller documentation to see how this is handled in
your particular system.

SCSI bus termination
Terminating the drive
ST446452W 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 TE jumper from pins 19 and 20 of connector J4A. If you
install the drive on the end of the SCSI bus, enable termination
by installing a jumper on pins 19 and 20 of connector J4A (see
Figure 4).

I/O circuits and data path widths
W models have a wide (16-bit) SCSI data bus rather than the
standard (non-wide) 8-bit SCSI data bus; however, you can use
these wide drives on a standard (non-wide) 8-bit data bus.

Providing adequate cooling
The enclosure design must ensure adequate cooling for the
drive. The MTBF (mean time between failure) value is based on
operating at a local ambient temperature of 30°C (86°F). The
maximum ambient temperature is 50°C.
The drive’s product manual (83329280) describes how to evalu-
ate the air-flow design. The evaluation consists of ensuring that
the case temperature of certain critical components remains
within acceptable limits during drive operation.
We recommend orienting the drive or directing the air flow in a
way that creates the least amount of air-flow resistance while
providing air flow above the circuit boards and around the head
and disc assembly (HDA). Also, choose the shortest possible
path between the air inlet and exit. This minimizes the distance
traveled by air that is heated by the drive and by other nearby
heat sources.
Figure 10 shows two design approaches with one or more fans
used to generate air flow. The air-flow patterns can be created by
the fans either pushing or drawing air. The overall flow pattern
can be directed from front to back, back to front, or side to side.

Kühlung des Systems
Die Gehäusekonstruktion muß eine ausreichende Kühlung des
Laufwerkes gewährleisten. Die Umgebungstemperatur darf max-
imal 50°C betragen.
Die Produkthandbuch Elite 47 (Dokument 83329280) enthalten
Anweisungen zur Beurteilung der Luftstromkonstruktion. Die
Beurteilung muß sicherstellen, daß sich die Gehäusetemperatur
bestimmter kritischer Komponenten bei Laufwerkbetrieb innerh-
alb zugelassener Grenzen hält.
Wir empfehlen, das Laufwerk so zu orientieren oder den Luft-
strom so zu lenken, daß der geringste Luftstromwiderstand
erzeugt wird und gleichzeitig ein Luftstrom über den Platinen
und um die Kopf- und Festplatteneinheit (HDA) gegeben ist.
Wählen Sie einen möglichst kurzen Weg zwischen Lufteinlaß
und -auslaß. Dadurch wird die Strecke, die die vom Laufwerk
und anderen nahegelegenen Hitzequellen aufgewärmte Luft
zurücklegt, auf ein Minimum beschränkt.
Abbildung 10 zeigt zwei Konstruktionsmöglichkeiten, bei denen
ein oder mehrere Lüfter den Luftstrom erzeugen. Der Luftstrom-
verlauf wird durch die Lüfter gesteuert, die entweder Luft einbla-
sen oder abziehen. Generell kann der Luftstrom entweder von
vorne nach hinten oder von hinten nach vorne verlaufen.

Mounting the drive and connecting cables
Do not touch the connector pins or any components on the con-
trol board without observing static-discharge precautions.
Always handle the drive by the frame only.
The drive may be mounted in any orientation (horizontally, verti-
cally, and any combination thereof); however, you must ensure
that the drive receives adequate air flow for cooling.
1. Mount the drive to the host system’s chassis using four 6-32
UNC screws. Two mounting holes are in each side of the
HDA and there are four mounting holes in the bottom of the
HDA.
The maximum length that the screws should extend into the
HDA mounting holes is 0.17 inch (4.318 mm), measured
from the outer surface of the HDA. Tighten the screws down
evenly. Do not over-tighten or force the screw if it does not
seem to screw in easily, because this means the threads are
not properly aligned. In this case, back the screw out and try
again.
Installation des Laufwerkes
und Anschluß der Kabel
Beachten Sie beim Handhaben und Anfassen der Anschlußstifte
und Komponenten die Vorsichtsmaßnahmen zur Verhinderung
statischer Aufladung. Fassen Sie das Laufwerk nur am Rahmen
an.
Das Laufwerk kann in beliebiger Orientierung (horizontal, ver-
tikal oder schräg) installiert werden; jedoch muß dafür gesorgt
werden, daß ein ausreichender Luftstrom zur Kühlung des Lauf-
werkes vorhanden ist.
34
Elite 47 Installation Guide, Rev. B
1. Befestigen Sie das Laufwerk mit vier 6-32-UNC-Schrauben
am Gehäuse des Host-Systems. Die beiden Seiten des
Laufwerkes sind mit jeweils zwei Befestigungslöchern
versehen, die Unterseite des Laufwerkes weist vier weitere
Befestigungslöcher auf.
Gemessen von der Außenfläche des Gehäuses dürfen die
Schrauben maximal 4,318 mm in die Befestigungslöcher
des Gehüuses hineinragen. Die Schrauben müssen gleich-
mäßig, jedoch nicht zu fest, angezogen werden. Wenn sich
eine Schraube nicht ohne Widerstand einschrauben läßt,
sind die Gewinde nicht korrekt aneinander ausgerichtet. In
diesem Fall die Schraube nicht in das Gewindeloch
forcieren, sondern die Schraube herausnehmen und erneut
in das Gewindeloch einführen.
2. Verify that all connections between the drive and the host
system are correctly installed.
2. Prüfen Sie, ob alle Verbindungen zwischen dem Laufwerk
und dem Host-System korrekt hergestellt sind.
3. Verify that you have correctly installed jumpers.
3. Stellen Sie sicher, daß die Kennungsbrücken installiert sind.
4. Connect the SCSI cable into the drive’s SCSI connector.
Take care not to stretch or crimp this cable, and do not block
the system’s cooling air flow with the cable.
The drive receives DC power through a 4-pin connector
mounted next to the SCSI connector. The output of a power
supply must meet SELV (safety extra low voltage) as
defined in IEC 950. Figure 11 provides the pin information
Elite 47 Installation Guide, Rev. B
35
for the DC power connector. To connect the DC power cable
to the drive, simply insert the cable end into the drive’s DC
power connector.
4. Schließen Sie das SCSI-Kabel an den SCSI-Steckverbinder
des Laufwerkes an. Das Kabel darf nicht gedehnt oder
gedrückt werden und es darf den Luftstrom zur Kühlung des
Systems nicht behindern.
Das Laufwerk wird über einen 4-poligen, neben dem SCSI-
Anschluß befestigten Steckverbinder mit Gleichstrom ver-
sorgt. Der Ausgang eines Netzteils muß SELV (safety extra
low voltage) nach IEC 950 entsprechen. Abbildung 11 zeigt
die Steckerbelegung für den Gleichstromanschluß. Zum
Anschluß des Gleichstromkabels an das Laufwerk das
Kabelende in den Gleichstromanschluß des Laufwerkes
stecken.

Note. Signal ground on the printed circuit board assembly
(PCBA) and the head and disc assembly (HDA) are con-
nected together in this drive and you cannot separate
them. Ensure the equipment in which you have mounted
the drive is connected directly to the HDA. Maximizing
the conductive contact area between HDA ground and
system ground may reduce radiated emissions.
If you do not want the system chassis to be connected to
the HDA/PCBA ground, you must provide a nonconduc-
tive (electrically isolating) method of mounting the drive in
the host system. This may increase radiated emissions
and is the system designer’s responsibility.
Hinweis:
Die Signalerde auf der Stromregelungskarte (PCBA) und
der Kopf- und Festplatteneinheit (HDA) sind in diesem
Laufwerk miteinander verbunden und können nicht
getrennt werden. Das Gerät, in das Sie das Laufwerk
eingebaut haben, ist ohne elektrisch isolierende
Stoßdämpfer direkt an die HDA und PCB angeschlossen.
Die elektromagnetische Strahlung kann reduziert wer-
den, indem Sie eine möglichst große leitende Kontak-
fläche zwischen der HDA-Erdung und der Systemerdung
vorsehen.
Wenn Sie das Systemgehäuse nicht an die HDA/PCBA-
Erdung anschließen wollen, müssen Sie das Laufwerk
auf nichtleitende Weise (galvanisch isoliert) im Host-Sys-
tem einbauen. Die daraus u.U. resultierende verstärkte

Formatting the drive
Warning.
Formatting a drive erases all user data. Be sure that
you understand this principle before formatting any
hard disc drive. It is not necessary to format a drive
that previously has been used to store data, unless
your intention is to erase all user data.
Note.
Seagate is not responsible for lost user data.
1. Turn on DC power.
2. Boot the system from a system floppy disc, CD, or from a
previously installed hard disc drive if there is one.
3. Format the disc drive. Elite 47 disc drives are designed to
operate with a variety of operating systems. Please refer to
your system or SCSI controller manual for information about
formatting and setting up the drive. Some quick desktop
system notes are provided below.
Quick reference desktop system notes
Note.
If you are unable to access the full capacity of this drive,
refer to your SCSI host adapter and operating system
instructions as there are many host adapter and operat-
ing system interactions which may limit your ability to use
the full capacity of high-capacity drives.
• DOS/Windows. Set the drive type in CMOS to “Zero,” “None,”
or “No hard drive installed.” Use FDISK.EXE and FOR-
MAT.EXE.
• Macintosh. Use Apple’s Disk Setup utility version 1.3.1 or a
third-party drive utility to initialize or format the drive. Apple’s
Disk Setup utilities prior to version 1.3.1 only work with drives
having special Apple firmware.
