QUANTUM  VP32170/32550S SATURN  JUMPER SETTING

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

 * = factory default


 J5 TE Termination Enable Jumper
 -------------------------------
  +---------+-----------+--------------------------------------------+
  | Jumper  | Setting   | Description                                |
  +---------+-----------+--------------------------------------------+
  |   TE    | OPEN      | Termination Disabled                       |
  |         | CLOSED x  | Termination Enabled                        |
  +---------+-----------+--------------------------------------------+
  |   TP    | CLOSED    | Termination Power Enabled                  |
  |         | OPEN      | Termination Power Disabled                 |
  +---------+-----------+--------------------------------------------+

 One of the requirements of the SCSI bus is that it be properly
 terminated. If more than one SCSI device is connected to the host,
 only the last one must be terminated. The TE (Termination Enable)
 jumper, when installed, enables an active termination circuit,
 thereby terminating the SCSI bus. With the TE jumper off, bus
 termination is disabled.

 NOTE
 There are no Terminator Resistor packs to remove on the Saturn
 products.

 At the factory, Quantum configures the Saturn VP31080/32170S hard
 disk drive with termination enabled; that is, with a jumper installed
 across the termination pins on jumper block J5. To disable
 termination, remove the jumper from the pins at location J5.


 TP Termination Power
 --------------------
 It is recommended that the drive be configured to provide Termination
 Power to the SCSI bus. This ensures that there is sufficient power
 along the entire SCSI bus. The Termination Power (TP) jumper, when
 installed, enables termination power to be provided by the disk
 drive.

 At the factory, Quantum configures the Saturn VP31080/32170S hard
 disk drive with termination power enabled; that is, with a jumper
 installed across the termination power pins on jumper block J5. To
 disable termination power, remove the jumper from the pins at
 location J5.


 A2/A1/A0 SCSI-Bus Device Identification
 ---------------------------------------
 Used in combination, the jumper settings across A2, A1, and A0 de-
 termine the Saturn 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.


 J3 Spin Delay SD Pins 13/14
 ---------------------------
 With the Spin Delay jumper installed, across pins 13-14 of Option
 Connector J3, the drive will start power up sequence immediately
 when power is applied. With the Spin Delay jumper removed the drive
 will power up when a START/STOP command is issued by the host
 adapter.

 By default, Quantum configures the drive with a jumper installed
 across pins 13-14.


 J3 Spindle Sync SY Pin 19
 -------------------------
 Saturn disk drives support synchronized spindle operation. Master or
 slave synchronized operation is set through a SCSI Mode Select Page.
 When the drive operates as a Master drive, it generates a spindle
 synchronization reference signal, SPINDL_SYNC_REF L. When operating
 as a slave, the drive synchronizes its spindle according to the
 SPINDL_SYNC_REF L input reference. The drive always maintains local
 speed regulation when no reference signal is applied.

 Pin 19, of Option Connector J3, is provided to facilitate
 installations where a 2-pin connector for SPINDL_SYNC_REF L will be
 used. For Saturn drives, pin 10 is provided as an alternate
 connection to facilitate installations where a 10-pin header is used
 to connect several remote features. The ground return is pin 20,
 although pins 2, 4, or 6 can be used for ground return.


 J3 Write Protect WP Pins 17-18
 ------------------------------
 To enable write protection on the drive, install the referenced
 jumper across pin pair 17-18 of Option Connector J3. To disable
 write protection from the drive, remove the jumper from pin pair
 17-18.


 J3 Remote LED Status Display
 ----------------------------
 Busy and Fault status for Saturn VP31080/32170S disk drives can be
 monitored remotely by connecting a remote Busy and a remote Fault
 display LED to the drive's Option Connector J3.

 Busy status is monitored remotely by connecting the cathode side of
 the remote Busy LED to the BSY_OUT L pin. The anode side of the LED
 connects to the +5 VDC OUT pin.

 Fault status is monitored remotely by connecting the cathode side of
 the remote Fault LED to the FLT_OUT L pin. The anode side of the LED
 connects to the +5 VDC OUT pin.

 Pin 07     FLT Out Fault display LED Option

 Pin 09     BSY Out Busy display LED Option

 Pin 11     +5VDC LED anode connection

 Pin 15 RESERVED Don't use!
