Introduction

This manual is organized to assist you in the installation
and operation of your Seagate Hawk 1LP (wide bus)
family disc drive. Family models are listed in the Prod­uct 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.

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 and if not installed and used in
accordance with these instructions, may cause inter-

ference to radio communications.

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 supplied as a sub-assembly and
are not subject to Subpart J of Part 15 of the FCC Rules

2 Hawk 1LP (Wide) Installation Guide, Rev. B
and Regulations nor the Radio Interference Regula-

tions of the Canadian Department of Communications.
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.

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 components. 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.

• Inspect drive for possible shipping damage. All claims
of this type should be filed promptly with the trans­porter involved. Save original packing materials to be
used when reshipping.

4 Hawk 1LP (Wide) Installation Guide, Rev. B

• 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.

• Do not unpack drive from its static shielded bag 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

Caution. The circuit assemblies and components

contained in this equipment can be degraded
or destroyed by Electrostatic Overstress
(EOS) or by Electrostatic Discharge (ESD).

Static electrical charges can accumulate
quickly on personnel, clothing and synthetic
materials. The electrostatic fields due to these
charges when brought in close proximity to
susceptible circuit assemblies and compo­nents, can result in degraded reliability or
immediate failure of the affected component
or assembly.

To insure optimum reliable equipment opera­tion, it is required that technical support per­sonnel discharge 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. If unavail­able, ground yourself frequently by touching
the metal chassis of the system before han­dling any components (this helps only if the
system is connected to a ground).

static-inducing carpeted areas.

Avoid

This proce­dure is especially important when handling
printed circuit boards (PCB's).

Safety instructions

1. The disc drive(s) are to be installed in a customer
supplied enclosure where the surrounding air does
not exceed 50oC.

2. Four (4) 6-32 UNC-2A screws are required for
installation. Maximum screw length into side of
drive is 0.15 inches (3.81 mm). Maximum screw
length into bottom is 0.20 in. (5.08 mm). Maximum
screw tightening torque is 6.0 in-lb (.675 NM) with
minimum thread engagement of 0.12 in (3.0 mm).

3. The power requirements are shown in the Product
Information section.

4. The power supply must satisfy the safety require­ments for SELV (Safety Extra Low Voltage) cir­cuits.

5. Service is to be provided by trained Seagate ser­vice personnel.

6. The incorporation of the disc drives listed in this
guide into a customer enclosure must meet the
appropriate safety requirements of the country in
which it is used (e.g. UL 1950, CAN/CSA-C22.2
No. 950-M89, DIN VDE 0805/05.90 and EN60950:
1988 (IEC 950).

Note.

Power must be off when connecting or disconnecting.

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 indi­vidual drive installation sections for specific information
on your drive model.

• Drive configuration: Select those drive features
that are appropriate to install the drive in the system.
In "W/WD" models this is done by installing or remov­ing 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 in­stalled 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
defined in 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.

Hawk 1LP (Wide) Installation Guide, Rev. B 9

• Low-Level formatting: All Hawk 1LP wide family
drive models are low-level formatted at the factory
and do not require this step during installation. If an
installed drive is low-level formatted, all user data will
be lost.

Note: Seagate Technology assumes no liability for lost

user data.

• Partitioning and high level formatting: A drive can
be sub-divided into "partitions" which behave as
individual drives within the system. Consult the sys­tem documentation for instructions on partitioning
and high level formatting. Information is also avail­able in bookstores and libraries.

Product repair information

Service requirements
The special facilities required for the manufacture of

these drives generally prohibit repair in the field. If
problems occur during installation, please contact your
supplier for assistance. Do not attempt to disassemble
or repair. Drives should be sent to the repair depot
through the purchase source, if possible. Please ob­serve the following cautions.

Caution.

• Handle drive with care. Do not drop, or bump hard.

• Never remove the cover of these disc drives. Serv­icing items in the sealed HDA (heads, media, actua­tor, etc.) require special facilities. The drive contains
no user purchasable parts or PCBs.

• Opening the sealed HDA voids the drive warranty.

• Applying a soldering device to the components on
the PCB voids the drive warranty.

• Do not connect or disconnect cables without first
removing power from the drive.
