6 Getting Started With Your SystemThe system board includes the following features:• Six PCI slots located in an expansion-card cage. Slots 1 and 2 are 3.3-V,64-bit, 133-MHz PCI-X slots; slot 3 is a 3.3-V, PCIe x8 lane; slots 4 through 6are 3.3-V, PCIe x4 lanes. Expansion-card slots accommodate full-height,full-length expansion cards. PCIe slots accommodate up to x8 expansioncards.• Dedicated PCI slot for an integrated SAS host bus adapter or an optionalintegrated RAID controller card with 256 MB of cache memory and aRAID battery.NOTE: System boot is not supported from an external device attached to aSAS or SCSI adapter, including SAS 5/E, PERC 5/E, or PERC 4e/DC. Contactyour technical support provider for the latest support information aboutbooting from external devices.• Two integrated Gigabit Ethernet NICs, capable of supporting 10-Mbps,100-Mbps, and 1000-Mbps data rates.• Six USB 2.0-compliant connectors (two on the front and four on the back)capable of supporting a diskette drive, a CD-ROM or DVD-ROM drive,a keyboard, a mouse, or a USB flash drive.• Optional remote access controller (RAC) for remote systems management.• An integrated VGA-compatible video subsystem with an ATI ES1000,33-MHz PCI video controller. This video subsystem contains 16 MB ofDDR SDRAM video memory (nonupgradable). Maximum resolution is1600 x 1200 with 64 K colors; true-color graphics are supported in thefollowing resolutions: 640 x 480, 800 x 600, 1024 x 768, 1152 x 864, and1280 x 1024. When the optional RAC is installed, the video resolutionis 1024 X 768.• Systems management circuitry that monitors operation of the system fansas well as critical system voltages and temperatures. The systemsmanagement circuitry works in conjunction with the systems managementsoftware.• Standard baseboard management controller with serial access.• Back-panel connectors include one serial, one video, four USB, andtwo NIC connectors.
