When installing narrow SCSI devices use a 68 pin to 50 pin converter
obtained from your supplier.
!
The 68 pin multi mode terminator must be installed as the last device on
the Ultra2 SCSI interface cable in order to terminate the SCSI bus
properly.
!
The optional SCSI tape drive address assignment is 2.
