Getting Started With Your System 3System FeaturesThe major hardware and software features of your system include:• One or two Dual-Core Intel® Xeon® Processors 5000 Sequence.• Support for symmetric multiprocessing (SMP), which is available on systems with two Intel Xeonprocessors. SMP greatly improves overall system performance by dividing processor operationsbetween independent processors. To take advantage of this feature, you must use an operatingsystem that supports multiprocessing.NOTE: If you decide to upgrade your system by installing a second processor, you must order theprocessor upgrade kits from Dell. Not all versions of the Intel Xeon processor will work properly asadditional processors. The upgrade kit from Dell contains the correct version of the processor and heatsink.• A minimum of 512 MB of 533 or 667 MHz (when available), Fully Buffered DIMMs (FBD),upgradable to a maximum of 16 GB by installing combinations of 256-MB, 512-MB, 1-GB or 2-GBmemory modules in the eight memory module sockets on the system board.• Support for up to six 3.5-inch, internal Serial-Attached SCSI (SAS) hard drives or six 3.5-inch,internal SATA hard drives.• Peripheral bay provides support for an optional optical drive and an optional half-height tapebackup unit (TBU).• An optional single, 1.44-MB, 3.5-inch diskette drive.• An optional CD, DVD, or combination CD-RW/DVD drive.NOTE: DVD devices are data only.• An intrusion switch that signals the appropriate systems management software if the top coveris opened.• An 800-W power supply.• Six system cooling fans.The 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-Xslots; slot 3 is a 3.3-V, PCIe x8 lane; slots 4 through 6 are 3.3-V, PCIe x4 lanes. Expansion-card slots2 through 6 accommodate full-height, full-length expansion cards. Slot 1 accommodates half-length expansion cards. PCIe slots accommodate up to x8 expansion cards.
