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  
Seagate sales representative if you need to order this

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  
12263496).Connectionmaybemadetoanygrounded

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

Measured with an average reading DC ammeter. Instan-  
taneous +12V current peaks will exceed these values.

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.  
7
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,  
be sure the peak starting current is available to each device.

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).  
See Figure 8.

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.

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

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.

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

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.

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.
