 Jumper Setting
 ==============

 Some drives were being manufactured with OPTION B. If your drive has
 OPTION B, J8 should have a jumper only if terminator power is not
 supplied by the initiator.

 x = Jumper set at factory


 J4  Service Connector Pin Assignment
 ------------------------------------
     ----+------+------+------+------+------+---PCB

         |      |      |      |      |      |
         +------+------+------+------+------+

 When an LED is connected to pins nine (+) and ten (-), that LED
 functions in the same manner as the LED which is mounted on the disk
 drive's faceplate. This is typically used in cases when the drive
 is mounted in a position where the LED is not visible or the face-
 plate is removed.

 Pins two through four are the RS-422 lines used to down load firmware
 updates to the microprocessor which are then stored on the disk. Pins
 three (transmit data) and four (receive data) are the main communica-
 tion lines. Pin two is used to debug the processor and for a non-
 maskable interrupt. Pins five and six are signal ground lines. Pin
 eight is used to synchronizes the spindles. Pin 9 may be used as
 term. power.

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

 SCSI ID jumpers (pins one through six on J6) are provided to con-
 figure each disk drve with a SCSI device ID for use in multiple SCSI
 device configurations.

 An ID of seven is the highest priority in a multiple device
 configuration, and is usually used by the initiator.

 The disk drive is shipped from the factory with an ID of six. This
 assures that sufficient jumpers are available for any address except
 seven, which is usually reserved for the host system.


 J6 Parity
 ---------
 x  7-8  CLOSED  Enables Parity detection
         OPEN    Disables Parity detection

 The parity disable jumper, pins seven and eight of J6, enables (in)
 or disables (out) odd parity detection by the disk drive.

 The disk drive is shipped with pins seven and eigth in, enabling
 parity detection.


 J6  Drive Power-Up Options
 --------------------------
  x  9-10  CLOSED   Start when power is applied
           OPEN     Wait for START Command

 Wait for START Command:  With no jumper pins nine and ten of J6, the
 disk drive does not spin up until the initiator issues a START/STOP
 UNIT command with the start bit set to one.

 Start When Power is Applied: When pins nine and ten of J6 are
 jumpered, the motor starts as soon as power is applied. The disk
 drive is shipped in this configuration.



 J8  Terminator Power Selection
 ------------------------------
      OPEN    The drive is prevented from supplying termination power
              to the SCSI bus.

 Power to the terminators may come internally from the disk drive or
 externally from the SCSI bus.

 The drive electronics are capable of sensing if the host is providing
 power to the terminators. If the host is not providing power, the
 disk drive automatically provides power to the terminators.



 J9  Single Ended or Differential
 --------------------------------

 Single Ended       Differential
      +---+           +---+
     1|o o|2         1|xxx|2
     3|xxx|4         3|o o|4
     5|o o|6         5|xxx|6
     7|o o|8         7|xxx|8

    11|o o|12       11|xxx|12
      +---+           +---+

 xxx = CLOSED

 The SCSI bus signals may be either single ended or differential. If a
 single ended signal is desired, configure J7 so that pins 3 and 4 are
 jumpered and all other pins on J9 are not.

       J1 +-----------------+ SCSI ID on Tailgate PCB, Differential
          |1 o     o 2 (LSB)|
          |3 o     o 4      |
          |5 o     o 6 (MSB)|
          +-----------------+

 If a differential signal is desired, an optional "tailgate" PCB must
 be added to the drive. The tailgate PCB must have J1 configured
 for the same ID as the disk drive. Additionally J9 must have jumpers
 on pins 1 and 2, 5 and 6, 7 and 8, 9 and 10, and 11 and 12, while
 pins 3 and 4 should not have a jumper.

   |                 |
   |                 |
   +-----------------+

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


 Drive Orientation
 -----------------
 The drives may be mounted in any position. Certain switching power
 supplies may emanate electrical noise, which can degrade the
 specified read error rate. For best results, orient the drives so
 that the PCB assemblies are not adjacent to these noise sources.

 Twelve mounting holes, four on the bottom and four on each side, are
 provided for mounting each disk into an enclosure. The size and
 location of these holes are identical to industry standards.

 Caution: Mounting screw lengths must be chosen so that no more than
 0.125 inch of the screw is available to enter the frame mounting
 hole. The screw length, if incorrect, will damage the PCB during
 installation and void the warranty. The torque applied to the
 mounting screws should be between 9 and 12 inch-pounds.


 Air Flow Requirements
 ---------------------
 It is recommended that air flow over the drive be a minimum of 25
 cubic feet per minute.


 Air Filtration System
 ---------------------
 The disks and read/write heads are assembled in a Class 100 environ-
 ment and then sealed within the HDA. The HDA contains an absolute
 filter, mounted inside the casing, to provide internal air
 filtration.


 Initiator-Target Configurations
 -------------------------------
 The SCSI initiator interface offers a number of unique advantages
 which facilitate the interconnection of the disk drive with one (or
 more) computer systems. Unlike traditional microcomputer disk
 interfaces, such as ST506, SCSI supports multiple peripherals and
 different peripheral types, all operating on the same bus structure.

 LXT SCSI drives also supports multiple initiator configurations
 consistent with the established arbitration cycle outlined in the
 SCSI standards. Configuration changes are made by SCSI address
 jumpers, which are set when the drive is installed in the system.

 The SCSI implementation used in the disk drive is intended to
 facilitate high-speed data transfers between the initiator and the
 drive. Interconnection between the initiator system(s) and the drive
 is via a fifty-pin ribbon cable. The drive may be configured as
 either single ended or differential.


 Interface Termination
 ---------------------
 Single Ended
 SCSI devices require proper interface termination. The first device
 and the last device on a SCSI bus daisy chain must be terminated.
 Remove the terminators from any devices in between. For instance, if
 a disk drive is in the middle of a SCSI bus daisy chain, remove its
 terminators.

 The terminator resistor pack's pin one is marked with a dot. Note
 that the PCB's hole/solder pad for pin one has a square outline,
 where as all the other holes/pads have a round outline. Also, note
 that pin one is always the closest pin to the power connector, J3.

 Note: All terminator packs (U40 through U42) must be oriented with
 the dot (pin one) toward J3 for the disk drive to work properly.

 As shipped, the interface signal lines are terminated with three re-
 movable 220/330 ohm resistor network packs.

 The devices driving the disk drive inputs should be open collector
 devices capable of sinking at least 48 milliamps at a voltage level
 of less than 0.5 volts DC (7438 or equivalent).

 Devices receiving the disk drive outputs should be of a SCHMITT
 trigger type to improve noise immunity (74LS14, 74LS240, or
 equivalent). The initiator should not load the bus with more than one
 standard low power Schottky transistor-transistor logic (LSTTL) input
 load per line, and should terminate all input signals with 220/330
 ohm terminators.


 Spindle Synchronization
 -----------------------
 The configuration for the synchronized-spindle bus is a twisted pair
 cable, daisy-chained from the master to each slave drive. This
 twisted pair cable is connected to the Service Connetor (J4) on each
 drive. The mating connector used on J4 is a Dupont part number
 69764-010 or Berg part number 6976410. The last slave drive on the
 bus will have a 2k ohm resistor from pin 8 (SPDL) to +5 volts. Pin 9
 on J4 may be used as term. power. The maximum cable lenght is 3
 meters.

                | +---------+-o----SPDL-+-o---------+-o-
                +--Twisted--o-pair------o-cable--GND+

 After power is reset, the drive will be in an independent spindle
 mode, not configured for either a MASTER or SLAVE mode. Each drive
 must be configured for the appropriate mode of operation. This
 configuration is accomplished via a MODE SELECT command with Page 4
 setting the RPL bits in byte 17, bits 0 and 1. The master drive will
 generate the spindle-synchronization sync pulses with the slave
 drives to receive the sync pulses. The connection between drives for
 the sync reference pulse, is a bi-directional line. The master can be
 either the host or a drive, that generates the sync reference pulse.


 J1 Pin Assignments and Connector
 --------------------------------
 LXT SCSI drives communicate with an initiator system via a fifty-pin
 connector. Pin twenty-five is not connected. Pin one is located on
 the end of J1 closest to the DC power connector, J3.

 Connection to J1 is via a nonshielded fifty-conductor connector,
 consisting of two rows of twenty-five female contacts on 0.1 inch
 centers.


 J3 Power Connector
 ------------------
 The DC power connector, J3 is a four-pin AMP MATE-N-LOCK connector,
 part number 3505430-1. The recommended mating connector is AMP part
 number 1-480424-0 using AMP pims part number 350078-4 (strip) or part
 number 61173-4 (loose piece).

      +------------+   pin 3    + 5 Volts Return
                       pin 4    + 5 VDC Supply


 J4 Service Connector
 --------------------
 Connector J4 is a service connector provided for serial input, the
 synchronous spindle, and the ability to carry the LED signal beyond
 the disk drive. The service connector has ten pins. Its mating
 connector is a Berg 6976410 part.


 Sector Size
 -----------
 The disk drive is shipped from the factory formatted with a default
 sector size of 512 bytes. The user can reformat the drive to the
 user's sector size, using the PList, and the user's configuration
 parameters.


 Buffering Scheme
 ----------------
 The disk drive buffer is either a 32-kilobyte data buffer. The buffer
 controller allows transfer to the disk and from the initiator
 simultaneously, or from the disk and to the initiator simultaneously.


 Power-Up Sequence
 -----------------
 DC power (+5 volts and +12 volts) may be supplied in any order. Both
 power supplies must be present and within the tolerances of the power
 sending circuit, before the motor will spin up. When the spindle
 reaches full speed, the actuator lock automatically disengages. The
 disk drive performs automatic SEEK calibration during start up for
 optimum SEEK performance. The drive spin up and becomes ready in 15
 seconds. The drive executes in recalibration sequence whenever power
 is applied or the SCSI START/STOP command invoked via the SCSI bus.


 Removable Faceplate
 -------------------
 The faceplate is screwed to the front of the HDA in some LXT models,
 and clipped to the front in others. The faceplate may be removed in
 installations that do not require it.

 Drive Mechanism
 ---------------
 The HDA is a sealed subassembly containing the mechanical portion of
 the disk drive. A brushless DC motor contained within the spindle hub
 rotates the spindle and is controlled by a dedicated microprocessor.
 Shock mounting is provided internally in the HDA and externally at
 vibration isolators to minimize transmission of vibration through the
 frame. The frame is the mechanical assembly holding the HDA and PCB.

 Error Conditions
 ----------------
 When the drive fails to achieve synchronization a Unit Attention with
 an additional Sense Code of 0x5C (RPL status change) will be posted.
 Additionally, if subsequent to achieving synchronization the drive
 detects a loss of synchronization and no I/O operation is beeing
 executed, a check condition of Unit Attention with RPL status change
 will be posted.

 If an I/O operation is beein executed, and no other error condition
 exists, the drive shall return a check condition status. The Sense
 Key will be Recovered Error if the drive is able to recover. If it is
 not able to recover, then the Sense Key will be Hardware Error, with
 an additional sense code of RPL status change.

 Note: The number of slave drives that can be directly attached to the
 master drive is dependent on zhe cable length and output capability
 of the open collector driver.

 A fault tolerant method would be dual 60 Hz +/- .01% crystal oscilla-
 tors as the master synchronized-spindle with a buffer output to each
 slave drive.

 The J2 connector on the front of the drive, pin 9 is +5 V, the
 maximum current rating is 100 milliamps. A preferred method would be
 an external power source.

 If the requirement is for an LED to be displayed on the drive, some
 allowance must be made, due to the same connector is used for both
 the LED and synchronized-spindle. The LED is connected from pin 10
 (-LED Drv) to pin 9 (+5 volts).


 Medium Type
 -----------
 The drive always returns a medium type of zero.


 Power-Up Testing
 ----------------
 The self-test sequence is performed upon power up, and is followed by
 the initialization sequence. When the drive is reset, either by the
 SCSI bus -RST signal or by the BUS DEVICE RESET message, only the
 initialization sequence is performed.

 Note: The self-test sequence can also be initiated via the SEND
 DIAGNOSTIC and RECEIVE DIAGNOSTIC RESULT commands, and these commands
 include options for more comprehensive diagnostics.


 Self-Test Sequence
 ------------------
 The self-test sequence is executed upon disk drive power up. The
 self-test sequence verifies the integrity of the hardware. This test
 is not an exhaustive hardware diagnostic, but simply a check of the
 major components for full functionality. The drive does not respond
 to a SELECTION phase on the SCSI bus for about the first 250 milli-
 seconds of the self-test. After 250 milliseconds have passed, the
 drive responds to  SELECTION with a BUSY status for 2 to 3 seconds.
 This time is spent completing the remaining self-test sequences,
 initializing the SCSI chip, and enabling the SCSI interrupts.


 Shipping
 --------
 At power down, the heads are automatically positioned over the non-
 data, dedicated landing zone on each disk surface. The automatic
 shipping lock solenoid is also engaged at this time. Maxtor ships the
 disk drive in single or multipack shipping containers. Users can ship
 the drive installed when the nonoperating shock and vibration limits
 are not exceeded.

MAXTOR    SCSI INSTALLATION

         GENERIC INSTALLATION PROCEDURE FOR A SCSI DRIVE
   -----------------------------------------------------------

 1. Install a 50 pin ribbon connector making sure pin 1, which
    can be identified by the striped edge of the cable, is closest
    to the power connector on the drive.

 2. Install a DC power cable to the back of the drive.

 3. Verify the SCSI ID selection.
    Note: SCSI ID usually needs to be set to 0 to be the boot drive.
    The last physical device on the SCSI bus must be terminated.
    Any other drive or SCSI device connected between the host and
    the device at the end of the bus must not be terminated.

 4. Apply power to the computer.

  4a. When memory test is complete go into your system's Standard
      C-MOS set-up.
      (Note:  There are various ways to get into C-MOS set-up,
      please refer to system's manual for instuctions.)

  4b. Set the drive type to "Not Installed". This intelligent drive
      will identify itself to the SCSI host adapter.

 5. Boot from a DOS diskette that has FDISK.EXE and FORMAT.COM on
    it. At the A> prompt type in FDISK. At the menu options select
    option 1 to create a DOS partition. Another menu will appear and
    from those options choose 1 to create a Primary DOS partition.
    Select yes to make 1 large partition and it will automatically
    become active. Then escape from FDISK.

 6. At the A> prompt type in FORMAT C:/S
    This does a high-level format on the drive and transfers the
    system files in order for the drive to be bootable.
    (Note: Maxtor SCSI drives are low-level formatted at the factory)

 7. The drive is now bootable. As a test remove the DOS diskette
    from A and press reset to re-boot the computer, a C> should be
    displayed, the drive is now ready for operation.
