Notes On Installation
=====================
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 in-stalled 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.
Drive installation
------------------
This section describes the physical mounting of the drive in the host
cabinet and the logical installation as a system member, which is
called drive setup.
Disc drive mounting
-------------------
Do not touch the connector pins or any PCB components without
observing static-discharge precautions. Always handle the drive by
the frame only.

+-----------------+
The drive will operate in all axis (6 directions).
The drive may be mounted in any orientation.
- Mount to host system chassis using four 6-32 UNC screws. Three
mounting holes are in each side and four in the bottom of the
drive. The maximum length that the screws should extend into the
side chassis mounting holes is 0.150 inch (3.81 mm), and 0.20 inch
(5.08 mm) into bottom holes, measured from the outer surface of the
chassis. The minimum thread engagement for all mounting screws is
.12 inch (3.0 mm). Tighten the screws evenly to a maximum torque of
8 in-lb. Do not over tighten or force when screw does not seem to
screw in easily (threads not correctly engaged).
- Verify that all connections between the drive and the host system
are correctly installed. Most cables have a contrasting color
stripe indicating pin 1.
- Verify option select and drive ID select jumpers and installation
of terminator resistor packs where applicable. Do not power up the
host system until the drive is mounted and the system cover is
replaced.
- Connect DC power connector to the drive (not required on "NC"
model drives).
- Replace the Host System cover.
- Turn on DC power.
- Boot the system from the floppy drive or from a previously
installed hard-drive if there is one.
- Proceed with drive setup of the new hard drive.
Grounding
---------
Signal ground (PCB) and HDA ground are connected together in the
ST11200 drives family and cannot be separated by the user. The
equipment in which the drive is mounted is connected directly to the
HDA and PCB with no electrically isolating shock mounts. If it is
desired for the system chassis to not be connected to the HDA/PCB
ground, the systems integrator or user must provide a nonconductive
(electrically isolating) method of mounting the drive in the host
equipment.
NOTES
Mounting holes three on each side, 6-32 UNC. Max screw length into
side of drive 0.15 in. (3.81 mm). Screw tightening torque 8.0 in-lb
max with minimum thread engagement of .12 in (3.00 mm).
Mounting holes four on bottom, 6-32 UNC. Max screw length into bottom
of drive 0.20 in. (5.08 mm). Screw tightening torque 8.0 in-lb max
with minimum thread engagement of .12 in (3.00 mm).
Power and interface connections can extend past the "A" dimension by
0.040 in (1.02 mm).
Decorative front panel.
Connector is centered (side to side) on drive within 0.020 in. (.508
mm).
SCSI interface cable connection
-------------------------------
Model ST11200 family are SCSI interface drives. On "N/ND" models,
system connection is via a 50 pin, SCSI connector. On "NC" models
system connection and DC power is via a single 80 pin SCSI connector.
Because of its shape, there is only one way the drive can mate with
the input connector. Pin 1 is noted in Figure 2. Some cables have a
contrasting color stripe on one edge to indicate pin 1. Strain relief
is recommended at the cable. Do not block system cooling air flow by
the routing of cables.

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 subassembly and are not subject to Subpart J of Part 15 of
the FCC Rules and Regulations nor the Radio Interference Regula-
tions of the Canadian Department of Communications. However, the
unit has been tested using proper shield-ing 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 reason-able 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 Communi-
cations.
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 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.
- 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.
Caution. The circuit assemblies and components contained in this
equipment can be de-graded or destroyed by Electrostatic Over-
stress (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 prox-imity to susceptable
circuit assemblies and components, can result in degraded reliabil-
ity or immediate failure of the affected com-ponent or assembly.
- 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 airride carrier
experienced in handling computer equipment.
To insure optimum reliable equipment operation, it is required
that technical support personnel discharge themselves by wear-
ing 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 50 o C.
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 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 require-
ments 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.
- 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, actua-tor, 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.
Initial setup information
-------------------------
For the initial setup connect the cables, set the SCSI bus address
and remove, install, or leave as is the SCSI I/O line terminator
resistor packs. These procedures are described in paragraphs
following.
Drive setup/SCSI interface drives
---------------------------------
The SCSI interface handles both drive geometry and defect management
internally or the "no drive installed" option can be selected for
systems with SCSI drives.
All SCSI interface drives are low-level formatted at the factory. If
you wish to low-level format the drive to optimize its performance
for your system, consult the controller documentation for information
on low-level formatting. Partitioning and high-level formatting can
be done through DOS by way of the FDISK utility for partitioning, and
FORMAT for high-level formatting. Consult your DOS manual for FORMAT
and FDISK command options.
Warning. If an installed drive is low-level formatted, all user data
stored on the drive is lost.
Seagate Technology assumes no liability for lost user data.
