Sufficient jumpers are available for any address except seven, which

 J2 LED
 ------
 When a LED is connected to the +LED and -LED pins on J2, 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 where the drive is
 positioned with the LED not visible and the faceplate removed.

 J6  Spindle Synchronization Control Option
 ------------------------------------------
   -----+-J6-+-PCB---+---------+---
        |3  1|       |   J2    |
        |4  2|       |         |
        +----+       +---------+

Pin 1 = Gnd
Pin 2 = Master Sync
Pin 3 = Reserved
Pin 4 = Slave Sync

This feature allows multiple drives to synchronize the angular
position of their spindles such that their INDEX signals line up to
within 40 microseconds of each other.

The drives are connected together with a twisted pair cable to
connectpins 1 through 4 of J6 to the same pins of all the other
drives that can be locked together. This cable can optionally be
connected to a 60 Hertz system clock. The spindles are synchronized
with a once per revolution pulse on the SLAVE SYNC pin (pin 4 of J6).

Note: The configuration of J6 is the same for all PCB fabrications.

Rotational Position Locking (RPL)
---------------------------------
The Rotational Position Locking (RPL) and Rotational Offset fields in
Mode Select Page 4 are used to control the spindle synchronization.
The two bits of the RPL field select one of four modes for rotational
position locking.

  +-----+------------------------------------------------------------+
  | RPL |  Mode                                                      |
  +-----+------------------------------------------------------------+
  | 00b | Indicates that spindle synchronization is disabled         |
  | 01b | The drive operates as a synchronized-spindle slave         |
  | 10b | The drive operates as a synchronized-spindle master        |
  | 11b | The drive operates as a synchronized-spindle master control|
  +-----+------------------------------------------------------------+

With 00b in the RPL field the drive spindle will be unsynchronized.
The unsynchronized drive will not output on the SLAVE SYNC or MASTER
SYNC pins. It will ignore pilses on the SLAVE SYNC pin. The default
is the UNSYNCHRONIZED mode.

A drive operating as a slave synchronizes its INDEX to the pulse on
the SLAVE SYNC pin. The drive synchronizes the first edge of the
INDEX pulse to the rising edge of the SLAVE SYNC pulse. SLAVE SYNC is
an open collector TTL signal with a frequency of 60 Hertz 0.25%. A
slave has 01b in the RPL field.

The one pulse per revolution on the SLAVE SYNC can come directly from
a drive configured to be a master. The master drive spins autonom-
ously and outputs a pulse which concides with its INDEX on pin 4 of
J6. There must only be one master on the cable. A master has 10b in
the RPL field.

A drive can provide a 60 Hertz signal on the MASTER SYNC pin (pin 2
of J6). A drive configured to do this is in the MASTER CONTROL mode
with 11b in the RPL field. Another device can buffer this signal and
transmit it on the SLAVE SYNC pin. A drive in the MASTER CONTROL mode
synchronizes its INDEX to SLAVE SYNC pulses received independent of
the pulses it output on the MASTER SYNC pin.

 JP5/JP6 Termination
 -------------------
 The master synchronization and slave synchronization wires are driven
 by the drives with open collector drivers. These drivers can sink
 over 300 milliamps, allowing both ends of the cable to be terminated
 with pull up resistors to +5 volts DC. For best results, terminate
 both of the cable with the characteristic impedance of the cable
 connected to +5 volts DC. Jumper JP5 will connect slave synchroniza-
 tion to a 150 ohm resistor to +5 volts DC. Jumper JP6 will connect
 master synchronization to a 150 ohm resistor to +5 volts DC.

Power-up Sequencing
-------------------
When a drive is commanded to be a slave, it checks the frequency of
the SLAVE SYNC pulses before it synchronizes to it. In a system of
drives, SLAVE SYNC pulses should be present before drives are
commanded to be slaves. This can be done by commanding a ready drive
to be a master, or the controller can generate SLAVE SYNC. The
controller may also command a drive to be a master control and buffer
the received MASTER SYNC pulses.

JP1/JP12 Drive Power-Up Options
--------------------------------
Note: This section only applies to drives with the Common Fabrication
PCB. All other drives will, by default, start when power is applied.

   +-------+-------+--------------------------------+
   | JP1   | JP12  | Mode                           |
   +-------+-------+--------------------------------+
   | OPEN  | OPEN  | Start by ID sequence           |
   | OPEN  | CLOSED| Start after 11-13 second delay |
   | CLOSED| OPEN  | Wait for START command         |
   |xCLOSED| CLOSED| Start when power is applied    |
   +-------+-------+--------------------------------+

In order to allow for system power supply constraints, which may
require minimizing surge current when powering up multiple disk
drives, four modes of start-up sequencing are provided.

Start by ID sequence
The disk drive delays spinup for approximately 11 to 13 seconds
multiplied by the SCSI ID. This allows power-up sequencing.

Start after 11-13 second delay
The disk drive delays spinup for approximately 11 to 13 seconds.

Wait for START command
The disk drives does not spinup until the initiator issues a START
STOP UNIT command with the start bit equal to one.

Start when power is applied
The motor starts as soon as power is applied.

 JP10/JP11  Terminator Power Selection
 -------------------------------------
    JP10  CLOSED Terminator power is external, from the SCSI bus.
    JP11  OPEN

 x  JP11  CLOSED Terminator power is internal, from the drive.
    JP10  OPEN

    JP10  CLOSED Terminator power is provided from the
    JP11  CLOSED drive and to the SCSI bus. Hence, the drive is at one
                 end of the SCSI bus with terminators in place and id
                 also supplying terminator power for the device at the
                 other end of the SCSI bus.

J2 Pin 7-8/JP2 Write Protect Option
------------------------------------
The write protect jumper is JP2 for the original fabrication PCB.
For the common fabrication OCB the write protect jumper is on pins 7
and 8 of connector J2.

    J2/JP2  CLOSED Data cannot be written to the drive; only READ
                   operations can be executed.
    x       OPEN   Allowing normal reading/writing.

J2 Pins 3-4/JP13 Parity Option
-------------------------------
The parity jumper is on pins 3 and 4 of connector J2 for the original
fabrication PCB. For the common fabrication PCB the parity jumper is
JP13.

  x J2/JP13 OPEN   Enables odd parity detection in the drive.
            CLOSED Disables odd parity detection in the drive.

Odd parity is always generated by the drive and provided to the SCSI
bus.

Other Jumpers
-------------
Other jumper positions not shown or not described herein are not user
selectable. These jumpers are for factory use only. Improper
operation may occur if non-user jumpers are changed.

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

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

Mounting
--------
The drive may be mounted on any axis. In any final mounting
configuration, ensure that the operation of the three shock mounts
which isolate the base casting from the frame is not restricted.
Certain switching power suppplies may emanate electrical noise, which
can degrade the specified read error rate. For best results, orient
the drive so that the PCB assembly is not adjacent to these noise
sources.

Eight mounting holes, four on the bottom and two on each side, are
provided for mounting the drive into an enclosure. The size and
location of these holes are identical to industry standard floppy
drives.

Caution: The casting is very close to the frame mounting holes in
some locations. Mounting screws lengths must be chosen such that no
more than 0.125 inch of the screw is available to enter the frame
mounting hole. The torque applied to the mounting screws must be
between 9 and 12 inch pounds.

Installation Requirements
-------------------------
The Panther SCSI disk drive must operate in a temperature range be-
tween 50*F and 122*F (10*C and 50*C). The drive should be installed
in applications where temperature extremes outside of this range are
avoided.

To maintain proper operating temperature, the Panther SCSI disk drive
must be mounted in such a way as to ensure adequate airflow across
the PCB.

Caution: These requirements must be met to ensure proper functioning
of the drive. If they are not met, data loss and/or permanent damage
to the drive will result.

J1 SCSI Connector
-----------------
Connection to J1 is via a non-shielded fifty-pin connector,
consisting of two rows of twenty-five female contacts on 0.1 inch
centers. Recommended strain-relief connectors are AMP part-number
1-499506-2, or Dupont part number 669002 (66900-250). Use of a keyed
connector is recommended.

J2 Auxiliary Connector (Jumper Bank)
------------------------------------
Connector J2 is an auxiliary connector providing remote or local
control of SCSI ID, and the ability to carry the LED signal beyond
the drive. The auxiliary connector is a Berg 68451-121, ten-pin part.
The mating connector is a 3M 3473-6010 part.

J3 Power Connector
------------------
The four-pin DC power connector J3 is similar to AMP's MATE-N-LOCK
connector, part number 350542-1. J3 however, is surface mounted to
the PCB rather than free-hanging as the AMP part is. The recommended
socket housing that is compatible with connector J3 is AMP part
number 1-480424-0. The recommended female socket part numbers
350078-4 (strip) or 61173-4 (loose piece).

J4 Ground Tab
-------------
The DC ground connector is a Faston-type connector, AMP part number
61761-2. The recommended mating connector is AMP part number 62187-1.
If wire is used, the hole in J4 will accommodate a maximum wire size
of 18 AWG. This wire should be grounded to the AC ground or to the
metal of the computer frame.

Sector Size
-----------
The drive is shipped from the factory formatted with 512 byte
sectors. Configuration parameters are default values in all optional
cases. It is recommended that users reformat the drive with the
user's sector size, using the Plist and the user's configuration
parameters.

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

The devices driving the 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).

Deviices receiving the drive inputs should be SCHMITT trigger type
to improve noise immunity; 74LS14, 74LS240, or equivalent. The
initiator should not load bus with more than one standard low power
Schottky transistor-transistor (LSTTL) input load per line.

Single Ended signal Termination
-------------------------------
Single ended operation is the mode of operation that is standard for
all Panther SCSI disk drives. To terminate a drive with the original
fabrication PCB, install resistor networks in locations RN8, RN6 and
RN3. To terminate a drive with the common fabrication PCB, install
resistor networks in locations RN14, RN10 and RN5.

As shipped (for single ended operation) interface signal lines are
terminated with three removable 220/330 ohm resistor network packs.
If for some reason you need to order these resistor network packs,
please call Maxtor Technical Support at 800-856-5333.

Differential Signal Termination
-------------------------------
Differential operation is available only as an option ordered from
the factory. It comes only on the Panther P1 with the common
fabrication PCB and is known as the P1-17DS. To terminate this drive,
install resistor networks in locations RN12, RN8, RN3, RN13, RN9 and
RN4.

As shipped (for differential operation) interface signal lines are
terminated with six removable 330/150/330 ohm resistor network packs.

Removable Faceplate
-------------------
The faceplate may be removed in installations where it is not
required. Remove the two e-clips and unplug the LED cable from the
PCB.

General

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.
