ST11200 Family Install Guide

Introduction

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 in accordance with these instruc­tions, may cause interference 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
and Regulations nor the Radio Interference Regula­tions 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.

ST11200 Family Install Guide2

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.

ST11200 Family Install Guide

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 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.

• Do not tamper with sealed top cover. Doing so voids
your warranty. The drive contains no user servicable
components. See Product Repair section for more
information.

• Visually inspect the shipping container for any obvi­ous damage.

ST11200 Family Install Guide4

• 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.

• Verify all parts listed on shipping bill are received with
the equipment. Discrepencies or damage should be
reported to the shipping company.

• 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.

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 susceptable circuit assemblies and
components, can result in degraded reliabil­ity or immediate failure of the affected com­ponent or assembly.

ST11200 Family Install Guide

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).

Avoid static-inducing carpeted areas.

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).

3. The power requirements are shown in Section 1.0

Product Information.

4. The power supply must satisfy the safety require-

ments for SELV (Safety Extra Low Voltage) cir­cuits.

5. Service is to be provided by trained Seagate ser-

vice 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).

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.

• Drive configuration: The user must select which of
the drive features are appropriate to enable for
installation in their system. This is done by installing
or removing of the user configuration jumpers found
on the drive PCB. "NC" models are probably config­ured by the host 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

• 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.

ST11200 Family Install Guide

• 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
boundaries and track information to the drive). Defect
management information is read from the drive by the
host system when required in the installation proce­dure. If an installed drive is low-level formatted, all
user data stored on the drive 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. See your system
documentation. Present day drive installation pro­grams have menus that lead you through these
installation procedures.

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 dissas­semble 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.
