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

 x = Jumpers set at factory

 J9, pins one through five, and J10 pins one through four, determine
 the disk drive operation modes. The jumpers are used primarily for
 isolation testing at the factory or authorized repair center.

 J2-1/3/4 CLOSED
 J2-2     OPEN
 J9       all OPEN
 J10      all CLOSED
 J11      CLOSED


 J2 Parity Option
 ----------------
  x J2-1  CLOSED  Enables odd parity detection in the disk drive.
          OPEN    Disables odd parity detection in the disk drive.

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


 J2 SCSI Identification Selection
 --------------------------------

   +----------+-----------------------+----------+
   | SCSI ID  |        Jumpers        |          |
   |          | J2-4  | J2-3  | J2-2  | Priority |
   +----------+-------+-------+-------+----------+
   |    0     | OPEN  | OPEN  | OPEN  |  Lowest  |
   |    1     | OPEN  | OPEN  | CLOSED|    .     |
   |    2     | OPEN  | CLOSED| OPEN  |    .     |
   |    3     | OPEN  | CLOSED| CLOSED|    .     |
   |    4     | CLOSED| OPEN  | OPEN  |    .     |
   |    5     | CLOSED| OPEN  | CLOSED|    .     |
   | x  6     | CLOSED| CLOSED| OPEN  |    .     |
   |    7     | CLOSED| CLOSED| CLOSED|  Highest |
   +----------+-------+-------+-------+----------+

 SCSI identification (ID) jumpers (J2, pin four, pin three, and pin
 two) are provided to configure each disk drive with a SCSI device ID
 for use in multiple SCSI device configurations.

 An ID of seven is the highest priority in a multidevice configura-
 tion, and is usually used for the initiator.

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


 J9  Disk Operation
 ------------------
    +-------+----------+---------+---------------+---------+
    |J9 Pin |Normal    |Open     |Self-Diagnostic|PCB      |
    |No     |Servo Mode|Loop Mode|Mode           |Test Mode|
    +-------+----------+---------+---------------+---------+
    |   1   |  OPEN    |  CLOSED |   CLOSED      | CLOSED  |
    +-------+----------+---------+---------------+---------+
    |   2   |  OPEN    |  CLOSED |   CLOSED      | CLOSED  |
    +-------+----------+---------+---------------+---------+
    |   3   |  OPEN    |  OPEN   |   CLOSED      | OPEN    |

    |   5   |  OPEN    |  OPEN   |   OPEN        | OPEN    |
    +-------+----------+---------+---------------+---------+


 J9 Remote Start/Stop
 --------------------
  x J9-6  OPEN    The disk drive starts immediately when power is
                  applied.
          CLOSED  Wait for START/STOP UNIT Command

 The remote start/stop jumper, J9, pin six, when installed, allows the
 disk drive to be started or stopped by using the SCSI START/STOP UNIT
 command.


 J10 Mode
 --------
 Pins 1, 2, 3, 4, 5, 6 CLOSED  Mode NORMAL


 J11 Termination Power
 ---------------------
 Pins 1, 2 CLOSED Mode TERMINATION POWER

 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 terminators from any devices in between. For instance, if
 the disk drive is in the middle of the string, remove its
 terminators.

 As shipped, interface signal lines are terminated with three
 removable 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 of
 less than 0.5 volts DC (7438-type or equivalent).

 Devices receiving the disk drive outputs should be of 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 Schotky transistor-transistor logic (LSTTL)
 input per line, and should terminate all signals with 220/330-ohm
 terminators.

 Self Configuration
 ------------------
 When the disk drive powers up, or when it is reset, it configures
 itself using the parameters and information saved on the disk drive
 from the previous format operation. This includes the disk drive's
 exact model number returned in the INQUIRY command and parameters
 in the MODE SELECT pages of parameters.

 A UNIT ATTENTION condition is created for each initiator whenever the
 disk drive has been reset (by a BUS DEVICE RESET message or a RESET
 condition), or when the MODE SELECT parameters have been changed by
 other initiators. The UNIT ATTENTION condition persists for each
 initiator until that initiator issues any command (other than
 INQUIRY) which clears the UNIT ATTENTION condition.

 If an INQUIRY command is received from an initiator with a pending
 UNIT ATTENTION condition (before the disk drive reports the CHECK
 CONDITION status), the disk drive reports any pending sense data and
 preserves the UNIT ATTENTION condition.

 If a REQUEST SENSE command is received from an initiator with a
 pending UNIT ATTENTION condition (before the disk reports the CHECK
 CONDITION status), the disk drive reports any pending sense data and
 preserves the UNIT ATTENTION condition in the sense data. The CHECK
 CONDITION, however, is cleared and a GOOD status is returned on any
 subsequent command. Any subsequent command then clears the UNIT
 ATTENTION condition from the sense data.
