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

 x = Jumper set at factory


 Jumper Options
 --------------
 On the Drive's PCB, there are eight pairs of jumper pins that allow
 you to control drive operation. When you change a jumper setting, the
 new setting is in effect when the drive is next powered on.

  +---------+-----------+-------------------------------------------+
  | Jumper  | Setting   | Description                               |
  +---------+-----------+-------------------------------------------+
  |   TE    | OPEN      | Termination Disabled                      |
  |         | CLOSED x  | Termination Enabled                       |
  +---------+-----------+-------------------------------------------+
  |   EP    | CLOSED x  | Parity checking enabled                   |
  |         | OPEN      | Parity checking disabled                  |
  +---------+-----------+-------------------------------------------+
  |   WS    | OPEN   x  | Wait/Spin disabled                        |
  |         | CLOSED    | Wait/Spin enabled                         |
  +---------+-----------+-------------------------------------------+
  |   A2    | CLOSED x  | A0, A1, and A2 are used in combination to |
  |   A1    | CLOSED x  | determine the drive's SCSI ID. The default|
  |   A0    | OPEN   x  | value is six.                             |
  +---------+-----------+-------------------------------------------+


 Jumper Options
 --------------
 The configuration of five jumpers control the drive's mode of
 operation:

     TE - Termination Enable

     EP - Enable Parity

     WS - Wait/Spin


 TE Termination Enable Jumper
 ----------------------------
 One of the requirements of the SCSI bus is that it be terminated with
 proper termination resistors. If more than one hard disk device is
 connected to the host, the last one must be terminated. The TE
 (Termination Enable) jumper, when installed, connects terminating
 resistors to the SCSI bus. With the TE jumper off, no resistors are
 connected.


 EP  Enable Parity Jumper
 ------------------------
 The Enable Parity (EP) jumper controls parity checking across the
 SCSI bus.

 Installing the EP jumper enables parity checking. Quantum ships
 ProDrive 700/1050/1225S hard disk drive from the factory with the
 EP jumper installed. Removing the EP jumper disables parity checking.
 The drive still generates parity, but does not perform parity check-
 ing. When the jumper is changed, the new setting takes effect at the
 next power on.


 WS  Wait/Spin Jumper
 --------------------
 The Wait/Spin (WS) jumper controls the Wait/Spin option. Quantum
 ships the ProDrive 700/1050/1225S hard disk drive from the factory
 with no WS jumper installed - that is, with the Wait/spin option
 disabled. With the Wait/Spin option disabled at power-on, the motor
 starts spinning automatically and the drive will become ready to
 perform read or write operations without the need for start command.
 To enable Wait/Spin option, install the WS jumper.

 With the WS jumper installed at power-on, the motor does not start to
 spin until the host sends a START/STOP UNIT command. This delay
 permits power sequencing, preventing the system power supply from be-
 ing overloaded by simultaneous demands for peak start current from
 multiple devices. Once the drive receives the START/STOP UNIT
 command, it will become ready to perform read or write operations.


 A2/A1/A0  SCSI-Bus Device Identification
 ----------------------------------------
 Used in combination, the jumper settings across A2, A1, and A0 de-
 termine the ProDrive 700/1050/1225S hard disk drive's SCSI-bus device
 identification (SCSI ID). By default, Quantum configures the drive
 with a SCSI ID of six; that is, with jumpers installed across the
 pins labeled A2 and A1, and no jumper installed across the pins
 labeled A0.

   +----------+-----------------------+
   | SCSI ID  |        Jumpers        |
   |          |  A2   |  A1   |  A0   |
   +----------+-------+-------+-------+
   |    0     | OPEN  | OPEN  | OPEN  |
   |    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|
   +----------+-------+-------+-------+

 The SCSI bus supports up to eigth devices, including the host system.
 A device's identification number determines its priority and must be
 unique in the system.
