The maximum cable length is 10 meters (393.37 in.). 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, use
the following guidelines:
a. Use cables no longer than 10 meters (393.37 in.) (LSI
recommends using shorter cables, ifpossible.)
b. Use cables that meet the SAS specification.
c. Route the SAS cables carefully.
Step 7. Turn on the Power to the System
Reinstall the computer cover, and reconnect the AC power
cords. Turn power on to the host computer. Make sure that the
power is turned on to the SAS devices, SATA II devices, or both
before or at the same time that the power is turned on to the
host computer. If the computer is powered up before these
devices, the devices 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 shows the MegaRAID 6Gb/s SAS RAID
controller number, firmware version, and cache SDRAM size.
The numbering of the controllers follows the PCI slot scanning
order used by the host motherboard.
Step 8. Run the WebBIOS Configuration Utility
Run the WebBIOS Configuration Utility to configure the drive
groups and the virtual drives. When the message Press
CTRL+H for WebBIOS appears on the screen, immediately
press CTRL+H to run the utility.
Step 9. Install the Operating System Driver
The SAS RAID controllers can operate under various operating
systems. To operate under these operating systems, you must
install the software drivers. The MegaRAID Universal Software
Suite CD includes software drivers for the supported operating
systems, along with documentation. You can view the
supported operating systems and download the latest drivers
