Introduction
This manual is organized to assist you in the installation and
operationofyourSeagateHawk2LPFamilydiscdrive.Family
models are listed in Hawk 2LP Family Product Information
section.It alsoprovides informationto aid inobtaining service
for the drive.
Before attempting any installation, please read through all
applicable sections of this document, including all warnings
and cautions.
Warning.
This equipment generates, uses, and can radiate radio
frequency energy andifnotinstalledandused in accordance
with these instructions, may cause interference to radio com-
munications.
Electromagnetic interference (EMI) considerations
The drive(s) described herein, as delivered, are designed for
system integration and installation into a suitable enclosure
prior to use. As such, the drive(s) described herein are sup-
plied as a sub-assembly and are not subject to Subpart J of
Part 15 of the FCC Rules and Regulations nor the Radio
InterferenceRegulationsoftheCanadianDepartmentofCom-
munications. However, the unit has been tested using proper
shielding and grounding and found to be compliant with the
Class A limits of the FCC Rules and the Regulations of the
Canadian Department of Communications.

2 Hawk 2LP Family Installation Guide, Rev. A
_____________________________________________________________________________________________________________
The physical design characteristics of the drive(s) described
herein, serve to minimize EMI radiation when installed in an
enclosure that provides reasonable shielding. As such, the
drive(s) are capable of meeting the Class B limits of the FCC
Rules and the Regulations of the Canadian Department of
Communications.
Note. It is the end users' responsibility to assure that the
drive(s) described herein meet the appropriate EMI
requirements of their system. Shielded I/O cables
may be required if the enclosure does not provide
adequate shielding. If I/O cables are external to the
enclosure, shielded cables should be used, with the
shields grounded to the enclosure and to the host
controller.

Before you begin
Verify that the system is switched off and disconnected
from main power before any installation is attempted.
Protect yourself, the drive, and your valuable programs
and data by reading the following cautions and warnings.
• Do not tamper with sealed top cover. Doing so voids your
warranty. The drive contains no user serviceable compo-
nents. See Product Repair section for more information.
• Visually inspect the shipping container for any obvious
damage.
• Verify all parts listed on shipping bill are received with the
equipment. Discrepancies or damage should be reported to
the shipping company.
• Inspectdrivefor possible shippingdamage.Allclaimsofthis
type should be filed promptly with the transporter involved.

• 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 drive fromits static shieldedbag untilyou are
ready to install it in the system.
• Always handle the drive by the frame or casting.
• Donottouch Printed CircuitBoard (PCB) or theI/O connec-
tor pins.
• Never apply pressure to the PCB or to the drive top cover
Caution. Thecircuit assembliesandcomponentscontained
inthis equipment canbedegraded ordestroyed by
Electrostatic Overstress (EOS) or by Electrostatic
Discharge (ESD).

Static electrical charges can accumulate quickly
onpersonnel,clothingandsyntheticmaterials.The
electrostatic fields due to these charges when
brought in close proximity to susceptible circuit
assemblies and components, can result in de-
graded reliability or immediate failure of the affect-
ed component or assembly.
To insure optimum reliable equipment operation, it
is required that technical support personnel dis-
charge themselves by wearing a grounding strap
around the wrist and be connected to a grounding
terminal while working in the vicinity of, and while
handling EOS/ESD susceptible assemblies/parts.
Ifunavailable,ground yourself frequentlyby touch-
ingthemetalchassisofthesystembeforehandling
any components (this helps only if the system is
connected to a ground). Avoid static-inducing car-
peted areas. This procedure is especially impor-
tant when handling printed circuit boards (PCB's).

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 theindividual driveinstallationsections
for specific information on your drive model.
•Drive configuration: Select those drive features that are
appropriate to install the drive in the system. This is done by
installing or removing user configuration jumpers found on
the drive PCB.
•Mechanical installation: After setting up the drive configu-
ration the drive must be mechanically installed into the host
system and the power and I/O cables attached. Previously
mentioned precautions should be observed.
• CMOS configuration: SCSIdrivesshould not bedefinedin
the CMOS. The SCSI host adapter uses 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.
