Preface
This manual contains information for users of Seagate®
Elite™ 9 SCSI disc drives. It provides support services,
performance specifications, and initial setup informa-
tion. Additional information is available in the Elite 9
Product Manual (part number 83328860). Contact your

Electrostatic discharge protection
Caution. Removal of circuit boards by personnel not
performing depot repair will damage com-
ponents 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 expo-
sure 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.Toavoiddamagingdriveelectronicassemblies,
observe the following precautions when installing or
servicing the drive:

• Ground yourself to the drive whenever the drive elec-
tronics are or will be exposed. Connect yourself to
ground with a wrist strap (Seagate part number

Seagate takes all reasonable steps to ensure that its
products are certifiable to currently accepted stan-

dards. Typical applications of these disc drives include
customer packaging and subsystem 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
compliancein 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
resultsareavailablethroughtheSeagateSafetyDepart-

General description
Elite 9 SCSI disc drives are high capacity, random-
access digital-data storage devices.An Elite 9 drive is
illustrated in Figure 1. Specifications and DC power
requirements for the drive are listed in a table following
the figure.
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,thediscdrivemustreceiveadequatecooling(refer
to “Providing adequate cooling”) and it must be suffi-
ciently grounded and shielded from emissions. The
Elite 9 Product Manual (part number 83328860) con-
tains guidelines for a properly designed enclosure.

A −10% tolerance is permissible during initial start of the
spindle but must return to ±5% before reaching 5,400RPM.
The ±5% must be maintained after the drive signifies that its
power-up sequence has been completed and that it can
accept selection by the host initiator.

See the +12V current profile in the Elite 9 Product Manual.
This condition occurs when the Motor Start option is en-
abled and the drive has not yet received a start motor
command.

See “Conducted noise immunity” in the Elite 9 Product
Manual. The specified voltage tolerance includes ripple,
noise, and transient response.
At power-up, the motor current regulator limits the +12V
current to an average value of less than 4.8A, although
instantaneous peaks may exceed this value. These peaks
should measure 5 msec duration or less.

Minimum current loading for each supply voltage is not less
than 7% of the maximum operating current shown.

Use separate ground returns for +5V and +12V supplies.
Where power is provided to multiple drives from a common
supply, carefully consider individual drive power require-
ments.Wheremultipleunitsarepoweredonsimultaneously,

Initial setup information
The following topics are presented to guide you through
the installation process. These topics are presented in
the order you should follow to properly install the drive.
• Setting the SCSI ID jumpers
• Terminating the drive
• Changing other applicable jumper options
• Synchronizing spindles
• Providing adequate cooling
• Mounting the drive and connecting cables
• Formatting the drive
Each option-jumper illustration identifies the original
equipment manufacturer (OEM) default factory setting.
These are the most commonly used settings but are not
necessarily the ones set for your particular system.
Elite 9 Installation Guide, Rev. B
19
Setting the SCSI ID jumpers
EachdeviceontheSCSIchainmusthaveauniqueSCSI
ID. The host system’s SCSI controller usually uses the
highest-numbered ID available (ID7 in non-wide sys-
tems); therefore the lower-numbered SCSI IDs are nor-
mally used for the other SCSI devices such as this Elite
disc drive.
Note. MostSCSIcontrollers(hostadapters)allowyouto
skip a SCSI ID. For example, you can have ID0,
ID1, and ID3 (skipping ID2). Other controllers do
not allow this; refer to your system or controller
user’s manual for details about its requirements
for proper SCSI device installation.
Use connector J4A to set the SCSI ID (Figure 2). Most
Elite disc drives are factory set with the SCSI ID set at 0.
To change the SCSI ID, install jumpers on the appropri-
ate pins as shown in the illustration.
If, after completing the installation process, the drive’s
LED does not show on/off activity when the host is
trying to communicatewith 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 user’s
manual to ensurethat you havenot violated its SCSI ID
numbering recommendations.

Terminating the drive
If you are installing the 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
atoneendoftheSCSIbuswiththeSCSIcontrolleratthe
other end (both are terminated). The bottom example
shows two additional SCSI devices connected exter-
nally—thismeanstheSCSIcontrollerisnolongeronthe
end of the SCSI chain and should not be terminated.

Synchronizing spindles
in multiple drive configurations
If you are installing two or more Elite 9 drives, you may
(optionally) synchronize their spindles to reduce the
latency associated with switching from one drive to
another.
Spindle sync cables are used to connect the drives.
Use pins 23 and 24 on the J4A connector to attach the
spindle sync cable. Pin 24 provides the reference index
signal (SSREF+) and pin 23 provides ground (GND).

Figure 9 illustrates a typical synchronized spindle
configuration.
After connecting each drive with spindle sync cables,
you must designate a master spindle sync reference
source. This master source is normally a disc drive
located on the same SCSI bus as the other drives you
want to synchronize with. To designate a drive as the
master, use SCSI interface commands. Refer to the
Product Manual for information about using these
commands.

Providing adequate cooling
Theenclosuredesignmustensureadequatecoolingfor
the drive. The maximum ambient temperature is 45oC.
The drive’s product manual (83328860) describes how
to evaluate 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
inletandexit. Thisminimizesthedistancetraveledbyair
that is heated by the drive and by other nearby heat
sources.
Figure 10 shows two design approaches with one or
morefansusedtogenerateairflow.Theair-flowpatterns
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 maximal 45oC betragen.
Die Produkthandbuch Elite 9 (Dokument 83328860)
enthalten Anweisungen zur Beurteilung der
Luftstromkonstruktion.DieBeurteilungmußsicherstellen,
daß sich die Gehäusetemperatur bestimmter kritischer
Komponenten bei Laufwerkbetrieb innerhalb
zugelassener Grenzen hält.
Wirempfehlen, dasLaufwerksozuorientierenoderden
Luftstrom so zu lenken, daß der geringste
Luftstromwiderstand erzeugt wird und gleichzeitig ein
Luftstrom über den Platinen und um die Kopf- und
Festplatteneinheit(HDA)gegebenist.WählenSieeinen
möglichstkurzenWegzwischenLufteinlaßund-auslaß.
Dadurch wird die Strecke, die die vom Laufwerk und
anderennahegelegenenHitzequellenaufgewärmteLuft
zurücklegt, auf ein Minimum beschränkt.
Abbildung 10 zeigt zwei Konstruktionsmöglichkeiten,
bei denen ein oder mehrere Lüfter den Luftstrom
erzeugen. Der Luftstromverlauf wird durch die Lüfter
gesteuert, die entweder Luft einblasen 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 control board without observing static-discharge
precautions. Always handle the drive by the frame only.
The drive may be mounted in any orientation (horizon-
tally, vertically, and any combination thereof); however,
youmustensurethatthedrivereceivesadequateairflow
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 drive and there are four mounting
holes in the bottom of the drive. See Figure 11.
The maximum length that the screws should ex-
tend into the chassis mounting holes is 0.140 inch
(3.56 mm), measured from the outer surface of the
chassis. 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 (horizon-
tal, vertikal oder schräg) installiert werden; jedoch muß
dafür gesorgt werden, daß ein ausreichender Luftstrom
zur Kühlung des Laufwerkes vorhanden ist.
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. Siehe Abbildung 11.
GemessenvonderAußenflächedesGehäusesdürfen
die Schrauben maximal 3,56 mm in die
Befestigungslöcher des Gehüuses hineinragen. Die
Schraubenmüssengleichmäßig,jedochnichtzufest,
angezogen werden. Wenn sich eine Schraube nicht
ohneWiderstandeinschraubenläßt,sinddieGewinde
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 SCSI ID jump-
ers and that you have properly terminated the SCSI
bus (see Figures 2, 3, 4, 5, and 6).
3. Stellen Sie sicher, daß die SCSI-Kennungsbrncken
und die Abschlußwiderstände, soweit erforderlich,
korrekt installiert sind. Siehe Abbildung 2, 3, 4, 5, und

Note. Signal ground on the power control board (PCB)
and the head and disc assembly (HDA) are con-
nected together in this drive and you cannot
separate them. The equipment in which you have
mounted the drive is connected directly to the
HDA and PCB without electrically isolating shock
mounts. 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/PCB
ground, you must provide a nonconductive (elec-
trically isolating) method of mounting the drive in
thehostsystem.Thismayincreaseradiatedemis-
sions and is the system designer’s responsibility.
Hinweis:
DieSignalerdeaufderStromregelungskarte(PCB)
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
werden, indem Sie eine möglichst große leitende
Kontakfläche zwischen der HDA-Erdung und der
Systemerdung vorsehen. Wenn Sie das
Elite 9 Installation Guide, Rev. B

Systemgehäuse nicht an die HDA/PCB-Erdung
anschließen wollen, müssen Sie das Laufwerk auf
nichtleitende Weise (galvanisch isoliert) im Host-
System einbauen. Die daraus u.U. resultierende
verstärkte elektromagnetische Strahlung fällt in
den Zuständigkeitsbereich des Systemdesigners.
5. Replace the host system’s cover.
5. Setzen Sie das Gehäuseoberteil des Host-Systems

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 which has
previously been used to store data, unless
your intention is to erase all user data.
1. Turn on DC power.
2. Boot the system from a system floppy disc or from a
previously installed hard disc drive if there is one.
3. Format the disc drive. The Elite 9 disc drive is de-
signedtooperatewithavarietyofoperatingsystems.
Refer to your system or SCSI controller manuals for
information about formatting and setting up the drive.
