RAID Array 3000 Controller Shelf
3.3.1SCSI Bus Target Addresses and Termination
NOTE
The SCSI bus address switch on the Controller Shelf device I/O module has been disabled. It does affect or control the SCSI bus addresses of the de- vices in the Device Expansion Shelves. The target addresses of the disk drives are set by address switch S3 on the personality module in each Device Expansion Shelf.
The SCSI bus device address and termination switches should be set before con- necting the SCSI cables between the Controller and Device Expansion Shelves. The SCSI bus addresses of the devices in each Device Expansion Shelf is set by address switch (S3) on the side of the personality I/O module in each shelf.
The SCSI bus termination on each device bus is set by the SCSI bus termination switch (S4) on the device I/O module of the Controller Shelf and the Personality I/O module on each Device Expansion Shelf.
The correct SCSI bus ID addresses and termination switch settings for single and multiple Device Expansion Shelf installations are shown on the diagrams that support the four following cabling procedures.
