Introduction
Thismanualisorganizedtoassistyouintheinstallation
and operation of your Seagate Hawk 1LP (wide bus)
family disc drive. Family models are listed in the Prod-
uct Information section. It also provides information to
aid in obtaining service for the drive. The Hawk 1LP
(wide) family drives have a 16 bit data interface.

warnings and cautions.
Warning.
This equipment generates,uses,andcanradiateradio
frequency energy and if not installed and used in
accordance with these instructions, may cause inter-
ference to radio communications.
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

ing and grounding and found to be compliant with the
ClassAlimitsoftheFCCRulesandtheRegulationsof
the Canadian Department of Communications.
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.

the drive(s)describedherein meetthe appro-
priate EMI requirements of their system.
Shielded I/O cables may be required if the
enclosure does not provide adequate shield-
ing.IfI/Ocablesare externaltotheenclosure,

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.
•Donottamperwith sealedtop cover.Doing sovoids
your warranty. The drive contains no user service-
able components. See Product Repair section for
more information.
•Visually inspect the shipping container for any obvi-
ous damage.
•Verifyallpartslistedonshippingbillarereceivedwith

reported to the shipping company.
•Inspectdriveforpossibleshippingdamage.Allclaims

•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.
•Donotunpackdrive fromits staticshielded baguntil
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

Caution. The circuit assemblies and components
containedinthisequipmentcanbedegraded
or destroyed by Electrostatic Overstress
(EOS) or by Electrostatic Discharge (ESD).
Static electrical charges can accumulate
quickly on personnel, clothing and synthetic
materials.Theelectrostaticfieldsduetothese
charges when brought in close proximity to
susceptible circuit assemblies and compo-
nents, can result in degraded reliability or
immediatefailureof the affectedcomponent
or assembly.
Toinsureoptimumreliableequipmentopera-
tion, it is required that technical support per-
sonnel discharge themselves by wearing a
grounding strap around the wrist and be

able,ground yourselffrequently bytouching
the metal chassis of the system before han-
dling any components (this helps only if the
system is connected to a ground). Avoid
static-inducing carpeted areas. This proce-
dure is especially important when handling
printed circuit boards (PCB's).

Safety instructions

Installation Overview
Installation of the drive can be divided into distinct
phases. Some of these may not be applicable to all
system installation requirements. Refer to the indi-
vidualdriveinstallationsectionsforspecificinformation
on your drive model.
•Drive configuration: Select those drive features
thatareappropriatetoinstallthedriveinthesystem.
In"W/WD"modelsthisisdonebyinstallingorremov-
ing user configuration jumpers found on the drive
PCB. For "WC" models, some of the configuration
parameters can be set 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 precautions
should be observed.
•CMOS configuration: SCSI drives should not be
definedintheCMOS.TheSCSIhostadapterusesits
own BIOS to handle the Input/Output procedures.
