Jumper Locations
The Viking II wide disk drive has two locations where user configurable jumpers are found. The
primary jumper block (Front option connector J3) for the Viking II wide drive is found on the front
edge of the disk drive printed circuit board. Using these jumper pins you can establish the various
drive configuration options. The secondary option jumper block provides an alternate method for
setting primary drive features. The alternate jumper block is located at the rear of the drive and is
incorporated into the SCSI cable connector.
The termination power option setting is located on the printed circuit board at the rear of the drive
and is near the SCSI cable connector.
