Preface

This manual contains information for users of the Seagate®
ST446452 Elite 47 SCSI disc drives. It provides support ser­vices, performance specifications, and initial setup information.
Additional information is available in the

Elite 47 Product Manua l

(part number 83329280). Contact your Seagate sales represen­tative if you need to order this publication.

Electrostati c discharge protection

Caution.

All drive electronic assemblies are sensitive to static electricity,
due to the electrostatically sensitive devices used within the
driv e circuitry. Although some devices such as metal-o xide semi­conductors are extremely sensitive, all semiconductors, as well
as some resistors 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 warranty.

Elect rostatic damage to elect ronic devices ma y 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 inst alling or servicing t he 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.

• Tur n off the power before removing or installing the DC power
cable.

2 Elite 47 In s ta lla t io n Gu id e, Rev. B

• Do not remove any circuit boards from the drive.

• Never use an ohmmeter on any circuit boards.

• When instal li ng the drive on a carri er or t ray, discharge the car­rie r o r tray pr io r to ins e rting it int o th e syst e m .

Important safety info rmation and precautions

Cauti on.

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 injur y. The warnings
point out conditions or practices that may endanger you or oth­ers . The cautions po int out condi tions or practi ces that m ay dam­age the uni t, possibly making it unsafe for use.

Always observe the following warnings and precautions:

• Follow all cautions and warnings in the proce dures.

• Use sound safety practices when operating, installing, or
removing the unit.

• Use caution when troubleshooting a unit that has voltages
present. Tur n 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 tem­peratures are usual ly highest.

• Follow the precautions listed above in “Electrostatic discharge
protection.”

Elite 47 Ins tal l a t ion G uid e, R ev. B 3

• 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 compo nents and may void th e warrant y.

• 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 by person nel not performing
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, CSA C22.2 950­M89, 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 cer tify 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 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 stand-alone
unit. Engineering radiated emissions test results are available
thr ough the Seagate Safe ty 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, zuver­lässigen 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 Risi ko behaft et ist.

Die Warn- und Vorsichtshinweise sind nicht allumfassend! Es ist
uns einfach nicht möglich, alle Wartungsmethoden oder die
event uellen 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 gewählt e Verf ahren weder Ihr e
persönliche Sicherheit noch die Leistung der Einheit gefährdet.

Beachten Sie in jedem Fall die folgenden Warn-und Vorsicht­shinweise:

• Beachten Sie alle Warn- und Vorsichtshinweise in diesem

Handbuch.

Elite 47 Ins tal l a t ion G uid e, R ev. B 5

• Treffen Sie beim Betrieb, bei der Installation oder bei der

Entfernung der Einheit angemessene Sicherheitsvorkehrun­gen.

• Wenn eine Einheit unter Spannung steht, gehen Sie bei der

Fehlerdiagnose besonders vorsichtig vor. Schalten Sie die
Einheit aus, bevor Sie m it den Installati ons-und Ent fernungsar­beit en beginnen.

• Wenn das Laufwerk in einem Einbaugestell oder Gehäuse

montier t ist, sorgen Sie dafür, daß die Temperatur im Inneren
des Gestells oder Gehäuses die für das Laufwerk vorgege­benen Grenzwerte nicht übersteigt. Wenn Einheiten vertikal
übereinander betestigt werden, achten Sie besonders auf den

General description

Elite 47 SCSI disc drives are high-speed, r andom-access digital­data 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 e xternal encl osure desi gned to house one or more di sc driv es
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 emis­sions. The

Elite 47 Product Manual

(par t number 83329280)

contains guidelines for a properly designed enclosure.

• 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 Ins tal l a t ion G uid e, R ev. B 19

SC SI ID jum pe r s

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 nor mally used for other SCSI devices such as this Elite disc
drive.

Note.

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 cont roller user’s m anual fo r
details about its requirements for proper SCSI device
installation.

This drive is a SCAM (SCSI Configured Auto Magically)
compli ant drive. If the system int o which you are installi ng
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 jump ers 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 tr ying 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 Ins tal l a t ion G uid e, R ev. B 21
user’s manual to ensure that you have not violated its SCSI ID

numbering recommendat ions.

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 sys­tem 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 con­troller is no longer on the end of the SCSI chain and should not
be ter minated.

Note.

Some controllers prefer to remain terminated even if they
are in the m iddle o f the ch ain. 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 sys tem .

ST446452W drives are terminat ed with permanent ly 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
Figur e 4).

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 st andard (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 evalu­ate the air-flow design. The evaluation consists of ensuring that
the case temperature of certain critical components remains
with in acceptab le 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 gen erate ai r fl ow. The ai r-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.

Kü hlun g de s Systems

Die Gehäusekonstr uktion muß eine ausreichende K ühlung des
Laufwerkes gewährleisten. Die Umgebungstemperatur darf m ax­imal 50°C betragen.

Die Produkthandbuch Elite 47 (Dokument 83329280) enthalten
Anweisungen zur Beur teilung der Luftstromkonstruktion. Die
Beurteilung muß sicherstellen, daß sich die Gehäusetemperatur
bestimmter kritischer Kom ponenten bei Laufwerkbetrieb innerh­alb zugelassene r Grenzen hält.

Wir e mpfeh len, d as Laufw er k so zu or ie ntie re n ode r d en Lu ft­strom so zu l enken, daß der geringste L uftstromwiders tand
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 Ko nstruktionsmöglichkeiten, bei denen
ein oder mehrere Lüfter den Luftstrom erzeugen. Der Luftstrom­verlauf wird durch die Lüfter gesteuert , die entweder Luft einbla­sen ode r abz iehen. Genere ll kann d er Luf tstrom ent wede r von

Mounting the drive and connecting cables

Do not touch the connector pins or any components on the con­trol board without observing static-discharge precautions.
Always handle the driv e by the fr ame only.

The drive may be mounted in any orientation (horizontally, ver ti­cally, and any combination thereof); however, you must ensure
that the drive receives adequate air flow for cooling.

1. Mount the drive to t he host system’s chassis using f our 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
fro m the outer surface of the HDA. Tighten the scre ws down
evenly. Do not over-tighten or force the screw if it does not
seem to scre w in easily, becau se this means the threads are
not properly al igned. In thi s case, back the sc rew out a nd try
again .

Installation des Laufwerkes
und Anschluß der Kabel

Beacht en Sie beim Handhaben und Anfassen der Anschlußstift e
und Komponenten die Vorsichtsmaßnahmen zur Verhinderung
statischer Aufladung. Fassen Sie das Laufwerk nur am Rahmen
an.

Das Laufwerk kann in beliebiger Orientierung (horizontal, ver­tikal oder schräg) installiert werden; jedoch muß dafür gesorgt
werden, daß ein ausreichender Luftstrom zur Kühlung des Lauf­werkes vor handen ist.

34 Elite 47 Installation Guide, Rev. B

1. Befestigen Sie das Laufwerk mit vier 6-32-UNC-Schrauben

am Gehäu se des Host-Systems. Die beiden Sei ten des
Laufwerkes sind mit jeweils zwei Befestigungslöchern
versehen, die Unterseite des Laufwerkes weist vier weitere
Befestigungslöcher auf.

Gemess en von der Außenfläche des G ehäuses dürfen die
Schrauben maximal 4,318 mm in die Befestigungslöcher
des Gehüuses hineinragen. Die Schrauben müssen gleich­mäßig, jedoch nicht zu fest, angezogen werden. Wenn sich
eine Schraube nicht ohne Widerstand einschrauben läßt,
sind die Gewinde nicht korrekt aneinander ausgericht et. In
diesem Fall die Schraube nicht in das Gewindeloch
forcieren, sondern die Schraube herausnehmen und erneut
in das Gewindeloch einführe n.

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 t hat you have correctly instal led jumpers .

3. Stel len Sie sicher, daß die K ennungsbrücken installiert sind.

4. Connect the SCSI cable into the drive’s SCSI connector.

Take care not to stret ch or crimp this cabl e, and do not bl ock
the sys tem’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 Ins tal l a t ion G uid e, R ev. B 35

for the DC power connector. To connect the DC power cab le
to the drive, simply insert the cable end into the drive’s DC
power connector.

Note. Signal ground on the printed circuit board assembly

(PCBA) and the head and disc assembly (HDA) are con­nected 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 radiat ed em issions .

If you do not want the system chassis to be connected to
the HDA/PCBA ground, you must provide a nonconduc­ti ve (el ectrically isolating) method of mounting the drive in
the host system. This may increase radiated emissions
and is the system designer’s responsibility.

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 intenti on is to erase all user data.

Note.

Seagate is not responsi ble f or lost use r dat a.

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 o r SCSI controll er manual for informati on about
formatting and setting up the drive. Some quick desktop
system notes are provided below.
