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

 x = Jumpers at the shipment


 The following jumpers are accessible for the user (use green jumper
 plugs, as for J8 use blue jumper plugs):

  SCSI ID setting jumper                 J8
  SCSI bus parity jumper                 J8
  Terminator power on/off jumper         JP5
  Write protected jumper                 JP4
  Motor Auto-start option jumper         JP2
  Synchronized spindle jumper            JP3
  Synchronized spindle Terminator        JP7
  Synchronized spindle signal connector  J7  Pins 1-2, 3-4

 Note: The DK516C jumpers other than listed above are installed by the
 manufacturer (black jumper plugs) and must not be modified or
 replaced by the user.

   +2-1+ x OPEN   +5V source for terminator is supplied only from the
                  drive controller. (Pins 4-3 CLOSED)

 Note: Terminator power source is supplied to the terminator resistor
 module from the host that pulls up the SCSI interface signals in the
 controller so that the SCSI bus lines will not be pulled down when
 DK516C power is turned down.


 JP4  Write Protected
 --------------------
     CLOSED  Write protected. The disk can be only read and cannot be
             written.
   x OPEN    Read or write. The disk is enabled for both read and
             write.

 ----------------------------------
  x 15-16 CLOSED The spindle motor is started automatically when power
                 is turned on.
          OPEN   The Spindle motor is not started automatically when
                 power is turned on. It can be started by using SCSI
                 command to start the drive.

 of these jumpers. The mode to be supported will be decided when power
 is turned on. The mode can be confirmed by MODE SENSE command and
 changed by MODE SELECT command*

 Whenever you change the orientation of the drive it is recommended to
 reformat the disks.


 Mounting
 --------
 In order to prove the shock protection ability, design the cabinet of
 a system as described in below.

 - Fix the drive with four screws by using the proper 4 screw holes
   (total of 8 holes) of the drive.
 - The insertion depth of the mounting screws below the drive surfaces
   must be less than
                     3.5mm (0.14inch) for side holes
                     5 mm (0.2 inch) for bottom holes


 Sequential Activation of Motors
 -------------------------------
 When multiple disk drives are connected and turned on simultaneously,
 a large amount of current will flow. It is recommended to turn the
 motors on one by one at an interval of approx. 35 seconds. Indication
 of "READY" on the last drive reports that all drives have been
 activated.

 Cable Connector BERG 65043-XX Female (XX = 33 (8 Pin), 34 (6 Pin)


 Terminator
 ----------
 The terminator of the controller other than last drive of SCSI Daisy
 Chain must be removed.
