3.3.1 SCSI 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.
