Keep PCI Express* Slot 3 empty for optimal air flow when populating a graphics card in PCI Express* slot 4. Note: Please follow the installation guide accompanying your graphics card for the power connection. Graphics cards with power greater than 75 W must be self-cooled with exhaust out the back of the chassis. Table 5. Graphics Card Population Optional Hardware Intel® SAS Entry RAID Module AXX4SASMOD The Intel® Workstation Board S5520SC provides a SAS module slot (J2J1) for the installation of an optional Intel® SAS Entry RAID Module AXX4SASMOD. Once the optional Intel® SAS Entry RAID Module AXX4SASMOD is present, the x4 PCI Express* links from the ICH10R to PCI Express* Slot 2 (x8 mechanically, x4 electrically) will switch to the SAS module slot. The optional Intel® SAS Entry RAID Module AXX4SASMOD includes a SAS1064e controller that supports x4 PCI Express* link widths and is a single-function PCI Express* end-point device. The SAS controller supports the SAS protocol as described in the Serial Attached SCSI Standard, version 1.0, and also supports SAS 1.1 features. A 32-bit external memory bus off the SAS1064e controller provides an interface for Flash ROM and NVSRAM (Non-volatile Static Random Access Memory) devices. The optional Intel® SAS Entry RAID Module AXX4SASMOD provides four SAS connectors that support up to four hard drives with a non-expander backplane or up to eight hard drives with an expander backplane. The optional Intel® SAS Entry RAID Module AXX4SASMOD also provides a SGPIO (Serial General Purpose Input/Output) connector and a SCSI Enclosure Services (SES) connector for backplane drive LED control. 14 Intel® Workstation Board S5520SC Service Guide
