 Pins 1 Write Protect
 --------------------
   OPEN   Drive looks at Mode Page header and responds accordingly;
          Default = NOT write protected
   CLOSED Drive is forced into the Write Protect Mode.


 Pins 2  SCSI-1/SCSI-2
 ---------------------
 When the SCSI-1/2 pin is active, and if the SCSI-1 mode is required,
 the jumper must be placed sideways.

   If the SCSI-1/2 pin is active
   OPEN   Drive looks at Mode Page 09, byte 8, bit 4 and responds
          accordingly; default = SCSI-2
   CLOSED Drive is forced to respond as a SCSI-1 device


 Pins 3 SDTR/UA
 --------------
 Mode Select page 23H determines whether the SDTR/UA (unit Attention)
 pin is active or not.

 When active, Mode Select page 23H determines whether the pin
 functions as SDTR or Unit Attention.

 If the SDTR function is active:
   OPEN   Inhibit drive initiation of SDTR message
   CLOSED Enable drive initiation of SDTR message at Power-On and
          Reset.

 If the Unit Attention function is active:
   OPEN   Enable Unit Attention
   CLOSED Inhibit Unit Attention


 Pins 4 LED Driver
 -----------------
 An LED requiring 10 ma may be connected across pinset 4.


 Pins 5 Auto Spin-Up
 -------------------
   OPEN   Drive will not spin up until Initiator sends Start Unit
          Command
   CLOSED Drive will spin up automatically at Power-On


 Pins 7, 8  SCSI pin 29
 ----------------------
   Note: Pinsets 7 and 8 have no effect if Sync Spindle Mode is
   disabled.

   7 and 8 OPEN       Not Allowed

   7 OPEN, 8 CLOSED   Connects Sync Spindle line to SCSI pin 29. When
                      Pinset 8 is CLOSED, pinset 7 MUST be OPEN.

   7 CLOSED, 8 OPEN   Connects SCSI pin 29 to ground. Upper pin of
                      pinset 8 is sync output in Master mode, or sync
                      input in Slave mode. When pinset 7 is shorted,
                      pinset 8 must be open.

   7 CLOSED, 8 CLOSED Not Allowed

 J4 Terminator Power Source Options
 ----------------------------------
 The single-ended drive is shipped with active terminator circuits
 installed. When installing multiple drives on the SCSI channel, the
 terminators must be disabled on all but the last drive in the chain.
 When the Terminator Enable jumper is installed, the terminator IC is
 active on the drive's SCSI bus connector; when removed, the
 terminator, are disconnect from the SCSI connector.

 Active terminators should be powered by Terminator voltage (TermPwr)
 whwnever the drive is connected to an active SCSI bus to avoid
 exceeding the bus high-state input current specification.
 The Terminator Power jumper determines the TermPwr source as listed
 below.

    1   Terminator Enable
    OPEN   On-board active terminators disabled. Terminators not
           connected to SCSI Connector.
    CLOSED On-board active terminators enabled and connected to SCSI
           bus. TermPwr source determined by placement of Terminator
           Power pinset jumper.

    3   Terminator Power
    OPEN   TermPwr for on-board terminators provided by the drive
           only. Drive TermPwr is not connected to SCSI connector pin
           26.
    CLOSED TermPwr for on-board terminators provided by the drive, and
           drive, and drive TermPwr is connected to SCSI connector pin
           26.

 Mounting Clearances
 -------------------
 Maintain a minimum clearance of 0.040 in. (1.0 mm) between any system
 structure and the top, bottom (PCA), sides (for bottom mounting) and
 ends of the disk drive. For side mounting, minimize the contact be-
 tween the drive and any system structure.

 Maintain a minimum clearance of 0.04 in. (1.0 mm) between any system
 structure and any PCA component.

 Use 6-32 UNC screws with flat washers under the heads and torque them
 to 15 inch-pounds (1.7 Newton-meters).

 When mounted, the screws should not protrude more than 0.25 in. (6.35
 mm) into the disk driveside or bottom mounting holes.
