CAUTION: Only trained service technicians are authorized to remove the system cover and access any of
the components inside the system. See your System Information Guide for complete information about
safety precautions, working inside the computer, and protecting against electrostatic discharge.
Installing a RAID Controller Card
Follow these general guidelines when installing a RAID controller card. For specific instructions, see the documentation
supplied with the RAID controller card.
NOTICE: To avoid possible data loss, back up all data on the hard drives before changing the mode of operation of the
integrated SCSI controller from SCSI to RAID.
1. Unpack the RAID controller card, and prepare it for installation.
For instructions, see the documentation accompanying the card.
2. Remove the bezel (see " Removing the Bezel ").
3. Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
4. Remove the cover (see " Removing the Cover ").
5. Install the RAID controller card (see " Installing an Expansion Card ").
6. Connect SCSI interface cables supplied with the card to the SCSIA and/or SCSIB connectors on the SCSI backplane
board.
NOTE: Cables can be connected from the RAID controller card to SCSIA and/or SCSIB backplane board
connector(s). A backplane board connector that is not attached to the RAID controller card will use the integrated
SCSI controller or optional integrated RAID controller.
To identify the connector on the RAID controller card, see documentation for the card. See Figure 5-4 to locate the
SCSI controller connectors on the SCSI backplane board.
Route the SCSI cables around the expansion-card guide and under the front-fan assembly to reach the RAID controller
card.
7. Connect the external SCSI devices to the card's external connector on the system's back panel.
If you are attaching multiple external SCSI devices, daisy-chain the devices to each other using the cables shipped with
each device.
8. Replace the cover (see " Removing the Cover ").
9. Remove the bezel (see " Removing the Bezel ").
10. Reconnect the system to its electrical outlet and turn the system on, including any attached peripherals.
11. Install any required SCSI device drivers (see "Installing and Configuring SCSI Drivers" in the User's Guide).
12. Test the SCSI devices.
Test a SCSI hard drive by running the SCSI Controllers test in the system diagnostics.
SCSI Backplane Board
The system contains a 3.5-inch diskette drive and a CD drive assembly mounted on the peripheral bay drive cage that
connects to the controllers on the system board. The system also contains up to six 1-inch SCSI hard drives that connect to a
controller on the system board or a RAID controller card through the SCSI backplane board.
