5 Reconfigure the SCSI cable connections to the SCSI backplane as necessary to
operate the backplane as a 2/5 split backplane:
• If a RAID controller card is not installed, cables are not required to use either the
integrated SCSI controller or optional integrated RAID controller in either a 1 x 5
or 2/5 split configuration.
• If a RAID controller card is installed, you can connect cables from the controller
card to SCSIA and/or SCSIB backplane board connector(s). A backplane board
connector that is not attached to the RAID controller card uses the integrated
SCSI controller or optional integrated RAID controller.
• If a cable is connected to the SCSIB backplane board connector, the SCSI
backplane daughter card must be installed in the system to activate the 2/5 split
configuration. Otherwise, the system displays an error message.
