all applicable sections of this document, including all
warnings and cautions.
Warning. This equipment generates, uses, and can
radiate radio frequency energy and if not

Electromagnetic interference (EMI) con-
siderations
The drive(s) described herein, as delivered, are de-
signed for system integration and installation into a
suitable enclosure prior to use. As such, the drive(s)
described herein are supplied as a sub-assembly and
arenotsubjecttoSubpartJofPart15oftheFCCRules
and Regulations nor the Radio Interference Regula-
tionsoftheCanadianDepartmentofCommunications.

the Canadian Department of Communications.

ST11200 Family Install Guide2
The physical design characteristics of the drive(s)
described herein, serve to minimize EMI radiation
when installed in an enclosure that provides reason-
able shielding. As such, the drive(s) are capable of
meeting the Class B limits of the FCC Rules and the
RegulationsoftheCanadianDepartmentofCommuni-
cations.
Note. It is the end users' responsibility to assure that
the drive(s)describedhereinmeettheappropri-
ateEMIrequirementsoftheirsystem.ShieldedI/
O cables may be required if the enclosure does
notprovideadequateshielding.IfI/Ocablesare
externaltotheenclosure,shieldedcablesshould
beused, withtheshields groundedtothe enclo-
sure and to the host controller.

Before you begin
Verify that the system is switched off and discon-
nected from main power before any installation is
attempted.
Protect yourself, the drive, and your valuable pro-
grams and data by reading the following cautions
and warnings.
•Donotunpackdrivefromits staticshieldedbag until
you are ready to install it in the system.
•Always handle the drive by the frame or casting.
•Do not touch printed circuit board (PCB) or the I/O
connector pins.
•Never apply pressure to the PCB or to the drive top
cover.
•Donottamperwithsealedtop cover.Doingso voids
yourwarranty.Thedrivecontainsnouserservicable
components. See Product Repair section for more
information.
•Visually inspect the shipping container for any obvi-
ous damage.

•Inspectdriveforpossibleshippingdamage.Allclaims
of this type should be filed promptly with the trans-
porterinvolved.Saveoriginalpackingmaterialstobe
used when reshipping.
•Verifyallpartslistedonshippingbillarereceivedwith
the equipment. Discrepencies or damage should be
reported to the shipping company.
Caution. The circuit assemblies and components
contained in this equipment can be de-
graded or destroyed by Electrostatic Over-
stress (EOS) or by Electrostatic Discharge
(ESD).
Static electrical charges can accumulate
quicklyonpersonnel,clothingandsynthetic
materials. The electrostatic fields due to
these charges when brought in close prox-
imity to susceptable circuit assemblies and
components,canresultindegradedreliabil-
ity or immediate failure of the affected com-
ponent or assembly.
•When transporting or shipping a drive or system,
please ensure that they are correctly packed in
original Seagate approved (or equivalent) container
and shipped via an air-ride carrier experienced in
handling computer equipment.

ST11200 Family Install Guide 5
To insure optimum reliable equipment op-
eration, it is required that technical support
personnel discharge themselves by wear-
ing a grounding strap around the wrist and
be connected to a grounding terminal while
workinginthevicinityof,andwhilehandling
EOS/ESD susceptible assemblies/parts. If
unavailable, ground yourself frequently by
touching the metal chassis of the system
beforehandlinganycomponents(thishelps
onlyifthesystemisconnectedtoaground).
Avoid static-inducing carpeted areas.

Installation Overview
Installation of the drive can be divided into distinct
phases as outlined below. Some of these may not be
applicableto yourparticularinstallation requirements.
Refer to the individual drive installation sections for
specific information on your drive model.
•Driveconfiguration: Theusermustselectwhichof
the drive features are appropriate to enable for
installationin theirsystem. Thisis doneby installing
orremovingof theuser configurationjumpersfound
onthe drivePCB. "NC"models areprobably config-
ured by the host over the 80 pin interface.
•Mechanical installation: After setting up the drive
configuration the drive must be mechanically in-
stalled into the host system and the power and I/
O cables attached. Previously mentioned precau-
tions should be observed
•SCSI drives should not be defined in the CMOS:
The SCSI Host adapter has its own BIOS to handle
the Input/output procedures. The CMOS setting for
SCSI drive is either drive type zero, or the "no drive
installed"option.

ST11200 Family Install Guide 9
•Low-level formatting: After the drive has been
properly configured for the system, it does not need
to be low-level formatted, as this has been done by
the factory and does not require this step during
installation. (The low-level format writes the sector
boundariesandtrackinformationtothedrive).Defect
managementinformationisreadfromthedrivebythe
host system when required in the installation proce-
dure. If an installed drive is low-level formatted, all
user data stored on the drive will be lost.
Note. SeagateTechnologyassumes noliability for
lost user data.
•Partitioning and high level formatting: A drive

grams have menus that lead you through these
