The maximum cable length is six external meters. You can connect one device per SAS PHY unless you use an expander.
System throughput problems can occur if the SAS cables are not the correct type. To minimize the potential for problems:
a.Use cables no longer than six meters (LSI recommends using shorter cables, if possible)
b.Use cables that meet the SAS specification
c.Route the SAS cables carefully
Step 9. Turn on the Power to the System
Replace the computer cover and reconnect the AC power cords; then, turn on the computer. Ensure that the SAS and/or SATA II devices are powered up before or at the same time as the host computer. If the computer is powered up before a SAS or SATA II device, the device might not be recognized.
During boot, a BIOS message appears. The firmware takes several seconds to initialize. The configuration utility prompt times out after several seconds. The second portion of the BIOS message displays the MegaRAID 8480 Storage Adapter number, firmware version, and cache SDRAM size. The numbering of the controller follows the PCI slot scanning order used by the host mainboard.
Step 10. Run the WebBIOS Configuration Utility
Run the WebBIOS Configuration Utility to configure the physical arrays and the logical drives. When the message Press <Ctrl><H> for WebBIOS appears on the screen, press CTRL+H immediately to run the utility.
Step 11. Install the Operating System Driver
The RAID controller can operate under various operating systems. To operate under these operating systems, you must install the software drivers.The MegaRAID 8480 CD includes software drivers for the supported operating systems, along with documentation. You can download the latest drivers at http://www.ibm.com/support/. For updates, click Downloads and drivers.
For details on installing the driver, refer to the MegaRAID 8480 Device Driver Installation User’s Guide on the MegaRAID 8480
