SCSI connection
The unit provides a 50-pin high density SCSI-2 port for connection of an
external storage system, for example, a LP (DVAD) or a RAID (DVAS) storage
array. To use this feature, connect the drive's SCSI cable to the SCSI-2
connector on the rear panel.
The Divar with internal DVD writer is delivered with a terminator connected to
the SCSI connector. Do not remove the supplied terminator from the SCSI
connector unless you connect a disk array!
The default SCSI ID of the Divar is 7. The SCSI ID of the internal DVD writer
is 6. If you are using a disk array make sure that the ID you select is different
from these IDs.
Adding additional storage arrays deletes all existing data!
