Jumper setting
==============

 J6 Shunt Block
 --------------
 01-16 : radial connection alway selected
 02-15 : auto-access during MST, the drive performs a repetitive
         series of moves.
 03-14 : without meaning
 04-13 : without meaning
 05-12 : unit 4 LUN 3
 06-11 : unit 3 LUN 2     (one out of four straps may be used to
 07-10 : unit 2 LUN 1     select the unit)
 08-09 : unit 1 LUN 0

Standard Position

 D570 on OMTI 20C (in easy-box or no)
      Only straps 4-13 and 6-11 are set. Choice explainable by the use
      of a D570 disk drive indicated under unit number 3. The
      adaptator-terminator 220/330 Ohms is always in RP1 location.

 D570 on DTC540E and OMTI5400
      Straps 4-13 and 8-9 are present for the livery disk drive with
      the streamer; the extensions disks will be strapped with the
      next unit number. Adaptator-terminator 220/330 in RP1 in
      first and last unit in the daisy-chain.

 NB:  In configurations with D570 and Maxtor we must respect rules for
      each disk drive type.
