Jumper Locations
The Viking disk drive has two locations where user configurable jumpers are found. The primary
jumper block (Front option connector J3) for the Viking 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 second option jumper block is used to set the Viking termination options. This jumper
block is found on the printed circuit board at the rear of the drive and is near the SCSI cable
connector.
