5. Configure the necessary disk enclosures for full-bus operation. See
Switches" on page
Set the disk enclosure DIP switches on both BCC A and BCC B to the following
settings for full-bus operation:
sw1=1 (This switch is set to 0 for split-bus mode.)
sw2=0
sw3=0
sw4=0
sw5=0
6. Install SCSI terminators on each disk enclosure. Install a SCSI Terminator on the
right-most connector on both the BBC A and BCC B cards.
An incorrectly terminated SCSI bus can cause data loss.

7. Install the SCSI cabling between the controller enclosure and the disk enclosures. Use
your expanded configuration diagram to determine how to connect the SCSI cabling. A
single SCSI cable will be used to connect each full-bus disk enclosure to the controller
enclosure.
To simplify disk array management, it is recommended that the SCSI cabling be
Note
connected to the disk enclosures according to where in the rack the enclosure
is installed. The disk enclosure closest to the controller enclosure should be
connected to SCSI channel 0. Moving down the rack, the next disk enclosure
should be connected to channel 1, the next to channel 2, and so on.
