SCSI ID Assignments
The SCSI ID’s for the ULTRAbloc Series enclosure are hard set and cannot be
changed in anyway. The ULTRAbloc Series enclosure has two modes of operation:
Single (Joined) SCSI bus mode (1x14), and Dual (Split) SCSI bus mode (1x7 and
1x7). The I/O Modules are set at ID 15 in all cases and SCSI ID 7 is reserved for
the host. The illustration below show how the SCSI ID’s are assigned.
