What are SCSI IDs and SCSI terminators?
Multiple SCSI devices can be “chained” together, and each device in the SCSI chain needs to have it’s own unique ID. The VS’s internal computer is set to SCSI ID #7. Therefore, externally chained SCSI devices can have IDs ranging from 0 to 6. If you connect one or more external SCSI devices to the VS, the last chain in the device must be terminated.
