Terminator resistor packs
-------------------------
On "WC" model drives the SCSI ID can be and presumably will be, set
over the 80 pin interface by the host computer. Unless directed to
do so by the system documentation, no jumpers should be installed
for address selection. On "WC" model drives, the host system also
has complete control over motor start functions, so no Motor Start
or Delayed Motor Start Jumpers should be installed.
Hawk 1LP family "W" model drives have terminator resistor packs that
are permanently installed, but can be enabled or disabled by jumper
plug. If you are installing a single drive, the terminator resistor
packs must remain enabled. If you are installing multiple hard disc
drives, disable the termination resistor packs from all the drives
but the one connected to the end of the SCSI I/O cable.
Model numbers that end in "WD" have differential I/O circuits and
these drives and "WC" model drives have no provisions for
terminators on the drive PCB. The system manufacturer must provide
some external means of I/O line termination. The Hawk 1LP family
"W/WD" model drives can provide power for external terminators if
the TP jumper is installed on the last position on the right end
of J2.
SCSI address selection
----------------------
On "WC" model drives the SCSI ID can be and presumably will be,
set over the 80 pin interface by the host computer. Unless directed
to do so by the system documentation, no jumpers should be installed
for address selection. On "WC" model drives, the host system also
has complete control over motor start functions, so no Motor Start
or Delayed Motor Start Jumpers should be installed.
Read/Write head autopark
------------------------
Seagate disc drives described herein mentioned in this drive park
the heads automatically at power off. This feature requires no
operator intervention.
Optional parity bit enable
--------------------------
Some systems require parity bit checking. Consult the system
documentation for the specific requirements. Jumper installed enables
parity reporting by the SCSI bus.
Write precompensation and reduced write current
-----------------------------------------------
Not required on Seagate SCSI Interface drives covered by this manual.
Drive configuration
-------------------
Each disc drive has option select header connectors on the back, side
and front where jumper plugs are installed to select the way that
the drive is to be configured or to select its ID on the I/O bus.
Some host systems have a remote drive ID selection capability.
Hawk 1LP family "WC" model 80 pin SCSI I/O drives
-------------------------------------------------
On Hawk 1LP family "WC" model drives there is no J1-auxiliary
connector. J6 can be used to set drive ID, but the host probably
does it over the 80 pin interface. J6 can also be used to drive
LED indicators and the synchronized spindle reference signal.
Drive ID on SCSI Bus
--------------------
On "WC" models the A3, A2, A1, A0 signals are on J6 and in the
80 pin J1 connector. Both should not be used to establish drive ID.

The drive will operate in all axis (6 directions).
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 may be mounted in any orientation.
- Verify that all connections between the drive and the host system are correctly installed. Most cables have a contrasting color stripe indicating pin 1.
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 ("W/WD" models only).
- Replace the Host System cover.
- Turn on DC power.
- Boot the system from the floppy drive or from a previously installed harddrive if there is one.
- Proceed with drive setup of the new hard drive.
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.
SCSI interface cable connection
-------------------------------
The Hawk 1LP family wide drives are SCSI interface drives. System
connection on "W" and "WD" models is via a 68 pin SCSI connector.
System connection for "WC" models is via an 80 pin SCSI and DC power
connector. The "WC" model plugs directly into a PCB or bulkhead
mounted mating 80 pin connector. Some cables have a contrasting
color stripe on one edge to indicate pin 1. On the Hawk 1LP wide
drives the I/O connector is keyed by virtue of its shape. There
is only one way it can mate with the mating input connector.
Strain relief is recommended at the cable in drives using
cables. Do not block system cooling air flow in routing of cables.
Grounding
---------
Signal ground (PCB) and HDA ground are connected together in the
Hawk 1LP wide drives 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.

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 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 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.
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.
- 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.
- When transporting or shipping a drive or system, please ensure that they are correctly packed in original Seagate approved (or equiva- lent) container and shipped via an airride 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 ground-
ing 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 handl-
ing any components (this helps only if the system is connected to a
ground). Avoid static inducing carpeted areas. 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 50*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). 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 supply must satisfy the safety requirements for SELV
(Safety Extra Low Voltage) circuits.
4. Service is to be provided by trained Seagate service personnel.
5. 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.
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.
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 subdivided 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.
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.
- Place drive on a flat, static dissipative surface and handle with extreme care. Always follow all EOS/ ESD precautions to avoid damage to the electrical assemblies.
Warranty: Contact your Seagate Authorized Distributor, Dealer or
other purchase source for warranty information.
Initial setup information
-------------------------
For the initial setup connect the cables or plug into a mounted
connector (if applicable), set the drive ID on the bus and enable or
disable the I/O line terminator resistor packs (Hawk 1LP family "W"
models only). These procedures are described in paragraphs following.
Note whether drive model number ends in W, WD or WC.
SCSI interface drives
---------------------
The SCSI interface handles both drive geometry and defect management
internally. The "no drive installed" option is selected for systems
with SCSI drives.
All SCSI interface drives are low-level formatted at the factory.
You may wish to low-level format the drive to optimize its perform-
ance 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.
