Press on the memory module with your thumbs while closing the ejectors with your index fingers to lock the memory module into the connector.
9.
Insert the RAID battery into the battery holder. See
10.
Thread the battery power cable through the hole in the back of the battery holder.
11.
Connect the battery power cable to the RAID battery cable connector on the riser card. See

14.
Reconnect the system to its electrical outlet and turn the system on, including any attached peripherals.
15.
Enter the System Setup program and verify that the setting for the SCSI controller has changed to reflect the presence of the RAID hardware. See
"Using the System Setup Program" in your User's Guide.

Install and configure the RAID software.
See the RAID software documentation for more information.
Installing a RAID Controller Card
See "
Installing an Expansion Card
" in "Installing System Components" for instructions about installing the card. See the RAID controller documentation for
information on installing and configuring the RAID software.
SCSI Hard-Drive Cabling Guidelines
Non-RAID Configurations
For a system without an optional RAID controller installed, connect SCSI channel A on the riser card to connector SCSIA on the SCSI backplane board. If the
optional external SCSI cable is installed, connect it to SCSI channel B on the riser card.
RAID Configurations
If the optional ROMB controller is enabled, or an optional RAID controller card is installed, you can configure the hard drives for RAID operation. The general
cabling configurations for various system options are discussed in the following subsections. For details on drive requirements for specific RAID types, see your
RAID controller documentation.
1x8 Drive Configuration
For a 1x8 drive configuration with no optional 1x2 backplane installed in the system, connect SCSI channel A on the riser card (see
Figure A
-4
) or SCSI channel
A on the optional RAID card to connector SCSIA on the 1x8 backplane (see
Figure A
-5
). Drive 0 functions as the boot drive.
1x8 plus 1x2 Drive Configuration
If an optional 1x2 backplane is installed in the peripheral bay, follow these guidelines:
l
Connect the 1x2 backplane to SCSI channel A on the riser card (see
Figure A
-4
) or SCSI channel A on the optional RAID controller card. Drive 0 in the
1x2 drive cage functions as the boot drive.
l
Connect a SCSI cable from connector SCSIA on the 1x8 backplane (see
Figure A
-5
)to SCSI channel B on the riser card (see
Figure A
-5
) or channel B of
the optional RAID controller card.
2x4 Split Backplane Configurations
l
To use the optional integrated ROMB controller in a split 2x4 backplane configuration:
¡
Connect SCSI channel A on the riser card (see
Figure A
-4
) to connector SCSIA on the SCSI backplane (see
Figure A
-5
). This channel controls the
boot drive (drive 0) and drives 1, 2, and 3.
NOTICE:
An optional daughter card must be installed on the back of the 1x8 SCSI backplane to support split 2x4 backplane operation.
