10. Watch the boot process until you see a BIOS message informing you of the key combination that you need to press to enter the LSI Corporation MPT SAS BIOS Configuration Utility*. A message similar to the following appears: Press + to start the LSI SAS Configuration Utility This message times out after several seconds. If you miss it, you will pass the option to get into the LSI Corporation MPT SAS BIOS Configuration Utility*. The firmware takes several seconds to initialize and then displays the Intel® RAID Controller SASUC8I number and firmware version. The numbering of the controllers follows the PCI slot scanning order used by the server board. Connecting the Cables This section describes the cables used on the SAS controller and provides instructions for connecting SAS and SATA hard disk drives to the SAS RAID controller. Note: Use only "straight" SAS cables, not "cross-over" SAS cables. A SATA connector consists of a signal connector and a power connector. The SAS connector adds a bridge (primary physical link) between the signal connector and the power connector. This means SAS backplane connectors can accept either drive type, but SATA backplane connectors can ONLY accept SATA drives. Figure 3 shows these connectors. Figure 3.
