 If these ID jumpers are used, the ID jumpers shown in left side view
 ARE NOT USED.


 SCSI address selection
 ----------------------
 On "N" and "ND" model drives, make sure that the SCSI bus address
 jumper(s) are properly set for the bus address assigned to the drive.
 Typically the primary boot device is set to ID 0, and the subsequent
 SCSI drives are jumpered in ascending order. Bus addresses 0 through
 6 should be used (the host adapter usually uses address 7). If the
 drive LED shows no on/off activity when the host is trying to
 communicate with it, an incorrect bus address selection at the drive
 should be suspected.

 On "NC" 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 "NC" 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.


 Terminator resistor packs
 -------------------------
 Model "N" drives and some model "NC" 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 "ND" have differential I/O circuits and
 these drives and some "NC" 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 "ND" model drives
 can provide power for external terminators if the TP jumper is
 installed on the last position on the right end of J2.


 Read/Write head auto-park
 -------------------------
 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.


 Drive configuration
 -------------------
 Each disc drive has one or more option select header connectors on
 the back, side or 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.


 Hawk 1LP family N/ND models (50 pin SCSI I/O)
 ---------------------------------------------
 On Model N/ND drives either J6 (on the front of the drive) or J5 (on
 the side behind the DC Power connector) may be used to set the drive
 ID. To avoid possible incorrect ID setting, do not use both J5 and J6
 for ID selection.


 Hawk 1LP family NC models (80 pin SCSI I/O)
 -------------------------------------------
 On Model NC drives there is no J5. J6 can be used to set drive ID,
 but the host probably does it over the 80 pin interface. J6 is used
 to select other configuration options as has previously been
 described.

 The drive will operate in all axis (6 directions).


 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. This is done by
   installing or removing user configuration jumpers found on the
   drive PCB.

 - 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.


 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.


 - 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 0.15 inch (3.81 mm), and 0.20
   inch (5.1 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 (.90 NM). 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.

 - 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 Hawk
 1LP family 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.

 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
   equivalent) 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).


 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). Screw tightening
    torques is 8.0 lb-in (.90 NM) max with minimum thread engagement
    of 0.12 in (3.00 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 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.


 Initial set-up 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 ("N" and some "NC"
 models). These procedures are described in paragraphs following.
 Note whether drive model number ends in N, ND or NC.

 SCSI interface cable connection
 -------------------------------
 Models Hawk 1LP family are SCSI interface drives.

 System connection is via a 50 pin SCSI connector.
 System connection for "NC" models is via an 80 pin SCSI and DC power
 connector. Normally the "NC" 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 "NC" models 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.


 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 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.
