   +-----------------+

 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.
