Installing the SCSI Backplane Daughter Card
1-7
To use the optional RAID controller card in a split backplane configuration:
a Connect SCSI channel A (channel 0) on the controller card to connector SCSIA on
the SCSI backplane. This channel controls the boot drive (drive 0) and drive 1.
b Connect SCSI channel B (channel 1) on the controller card to connector SCSIB on
the SCSI backplane. This channel controls drives 2 through 5.
NOTE:
If a cable is connected to the SCSIB backplane connector, the SCSI backplane daughter
card must be installed to activate the 2/4 split backplane configuration. Otherwise, the system will
display an error message.
10 Rotate the drive bay retraction bar toward the back of the system.
11 Close the system.
12 Enter System Setup to ensure that the RAID or SCSI controller card is configured correctly.
See your system’s
User’s Guide for more information.
13 Replace the bezel (if applicable).
