Step 5 Configure and Install the SAS Devices, SATA

II Devices, or Both in the Host Computer Case

Refer to the documentation for the devices for any
pre-installation configuration requirements.

Step 6 Connect the RAID Controller to the SAS

Devices, SATA II Devices, or Both

Use SAS cables to connect the SAS RAID
controller to SAS devices, SATA II devices, or
both. Refer to Figure 1 to view connector
locations on the controller.

Refer to the MegaRAID 1078-based SAS RAID

Controllers User’s Guide on the MegaRAID
Universal Software Suite CD for detailed

information about the SAS cables.

Step 7 Turn on the Power to the Computer

Reinstall the computer cover, and reconnect the
power cords. Turn on the power to the computer.
Make sure that the power is turned on to the SAS
devices and the SATA II devices before or at the
same time that the power to the host computer is
turned on. If the power is turned on to the
computer before it is turned on to the devices, the
computer might not recognize the devices.
