NOTE: The SCSI bus address switch on the controller shelf device I/O module does not
control the target addresses of the SBB slots in the device expansion shelves. This switch
has been electrically disabled by design. Refer to the StorageWorks SBB Shelf I/O Module
User’s Guide supplied with the device expansion shelf for a description of how to set the
SCSI IDs in each shelf.
SCSI bus termination switch S4 configures the SCSI bus termination of the
device expansion shelves in the RAID Array 3000 storage system. The proper
settings for S4 are included in the Chapter 3, “Installation and Maintenance.”
