QUANTUM  QM 31700AT/32550AT SIROCCO  JUMPER SETTING

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

 The QM31700AT/QM32550AT has three drive mode jumper options:
 DS (Drive Select), SP (Slave Present) and CS (Cable Select).

 The PK jumper is used for store spare jumpers.


 JP1  Drive Select/Cable Select/Slave Present
 --------------------------------------------
 +---+---+---+-------+---------------------------------------------+
 |CS |DS |SP | Pin 28|           Description                       |
 +---+---+---+-------+---------------------------------------------+
 | 0 | 0 | 0 |   X   |Drive configured as a slave.                 |
 +---+---+---+-------+---------------------------------------------+
 | 0 | 1 | 0 |   X   |Drive is configured as Master.               |
 +---+---+---+-------+---------------------------------------------+
 | 1 | 0 | 1 | OPEN  |Drive configured as a slave.                 |
 +---+---+---+-------+---------------------------------------------+
 | 1 | 0 | 0 | GND   |Drive is configured as Master.               |
 +---+---+---+-------+---------------------------------------------+

 NOTE
 In the table below, a 0 indicates that the jumper is removed, a 1
 indicates that the jumper is installed, and an X indicates that the
 jumper setting does not matter.



 Master Drive
 ------------
 The Master of a two drive configuration or as the only drive
 (if the slave drive uses DASP).
 DS CLOSED
 SP OPEN
 CS OPEN


 Drive Select
 ------------
 The DS jumper is used to identify the drive as a Master drive in a
 single or dual drive configuration.


 Master in a two drive system
 ----------------------------
 If the Slave drive does not use DASP
 DS CLOSED
 SP CLOSED (Slave present)
 CS OPEN


 Slave Drive
 -----------
 A Slave drive in a two drive configuration:
 DS OPEN
 SP OPEN
 CD OPEN


 Slave Present
 -------------
 The SP jumper is only used when the second drive in a two drive
 configuration does not support DASP. DASP (Drive active/drive 1
 present) is a CAM (Common Access Method) defined signal that
 indicates the presence of a second drive, DASP is used during power
 on initialization and after a reset. Prior to this definition,
 products were introduced which did not utilize this method to detect
 the presence of a second drive. The SP jumper is only used on the
 Master drive, with the DS jumper, when the second drive does not
 support DASP.



 Cable Select
 ------------
 The CS (Cable Select) jumper is only used in systems that support
 this feature. Cable Select allows for each IDE disk drive to be
 jumped the same and the position on the cable determines the ID.
 This requires special cable and both drives on the interface would
 have to support this feature.

 When two Sirocco 1700/2550AT hard disk drives are daisy-chained
 together, they can be configured as Master and Slave by using the CS
 jumper or by using the DS jumpers. To configure the drive as a
 Master or Slave with the CS feature, the CS jumper is installed.

 Once you install the CS jumper, the drive is configured as a Master
 or Slave by state of the Cable Select signal, which is pin 28 at the
 IDE-bus interface connector. Please note that pin 28 is a vendor-
 specific pin that Quantum is using for a specific purpose. More than
 one function is allocated to CS, according to the ATA CAM specifica-
 tion. If pin 28 is 0 (grounded), the drive is configured as a Master.
 If it is a 1 (high), the drive is configured as a Slave. In order to
 configure two drives in a Master/Slave realationship using the CS
 jumper, you need to use a cable that provides the proper signal
 level at pin 28 of the IDE bus connector. This allows two drives to
 operate in a Master/Slave realtionship according the drive cable
 placement.


 Drive Select Jumper
 -------------------
 You can also daisy-chain two drives on the IDE bus interface by using
 their Drive Select (DS) jumpers. To use the DS feature, the CS jumper
 must be removed.

 To configure a drive as the Master (Drive 0), a jumper must be
 installed on the DS pins.

 The Quantum Sirocco 1700/2550AT hard disk drives are shipped from the
 factory as a Master (Drive 0 - DS jumper installed). To configure a
 drive as a Slave (Drive 1), the DS jumper must be removed. In this
 configuration, the spare jumper removed from the DS position may be
 stored on the PK jumper pins.

 NOTE
 The order in which drives are connected in a daisy chain has no
 significance.

 Notes On Installation
 =====================


 J1A/B/C  DC Power/Interface Connector
 -------------------------------------
 The drive's DC power can be applied to either section A or B.
 The IDE-bus interface (40-pin) uses section C.
