                 Enable termination on a SCSI channel if the controller
                 is installed at one end of that channel. This setting
                 terminates the channel and power s its SCSI TERMPWR
                 signal.

                 Disable termination on a SCSI channel if the controller
                 is not at the end of that channel (both external and
                 internal devices exist on the same channel).

                                     (Cache holds data that needs to be
                                             written to disk)

  JP5/pins 5 & 6        Off                 No write is pending

  Note: If the system loses power or is reset while JP6/pins 5 & 6 are
  on, the data in cache memory will be lost. Install the optional cache
  batter backup module J2 to avoid data loss.
