Jumper Locations 

 

The Atlas II disk drive has two locations where user configurable jumpers are found. The primary jumper block (Front option 
connector J3) for the Atlas II 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 Atlas II 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.
