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 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-
ate EMI requirements of their system. Shielded
I/Ocablesmayberequirediftheenclosuredoes

beused,with theshieldsgroundedto theenclo-
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.

•Donotunpackdrive fromitsstaticshieldedbaguntil
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.
•Donottamperwith sealedtopcover.Doingsovoids

Caution. Thecircuitassembliesandcomponentscon-
tained in this equipment can be degraded or

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 (PCBs).

Installation Overview
Installation of the drive can be divided into distinct
phases as outlined below. Some of these may not be
applicable to your particular installation requirements.
Refer to the individual drive installation sections for
specific information on your drive model.
•Driveconfiguration:Theusermustselectwhichof
thedrivefeaturesareappropriatetoenableforinstal-
lationintheirsystem.Thisisdonebywayoftheuser
configuration jumpers found on the drive PCB.
•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.
8Hawk 2 Family Installation Guide, Rev. C
•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
canbesub-dividedinto"partitions"whichbehaveas

documentation. Present day drive installation pro-
grams have menus that lead you through these
installationprocedures.
