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 (using shorter cables
is preferred)
b. Use cables that meet the SAS specification
c. Route the SAS cables carefully
Step 9. Turn on the Power to the System
Reinstall the computer cover, and reconnect the AC 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 as the host computer. If the power
is turned on to the computer before it is turned on to the
devices, the computer might not recognize the devices.
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 ServeRAID-MR10is controller
number, firmware version, and cache SDRAM size. The
numbering of the controller follows the PCI slot scanning order
used by the host mainboard.

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.
