considerations
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.
Note. Itistheendusers'responsibilitytoassurethat
the drive(s)describedhereinmeettheappro-
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.
•Donottamper withsealed topcover.Doingsovoids
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.

•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.
•Donotunpack drivefrom itsstaticshieldedbaguntil
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

or destroyed by Electrostatic Overstress
(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 susceptible circuit assemblies and
components,canresultindegradedreliabil-
ity or immediate failure of the affected com-
ponent or assembly.
To insure optimum reliable equipment op-
eration, it is required that technical support

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.
Thisisdonebyinstallingorremovinguserconfigura-
tion jumpers found on the drive PCB.
•Mechanical installation: After setting up the drive
configuration the drive must be mechanically in-
stalledinto 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.
TheCMOS settingfor SCSI driveis eitherdrivetype
zero, or the no drive installed option.
