System Features 
The system offers the following features: 
l One or two Intel®Xeon™microprocessorswithaninternaloperatingspeedofatleast1.8GHzforthe400-MHz processor and 2.4 GHz for the 533-MHz 
processor, a level 2 cache of 512 KB, and a front-sidebusoperatingat400or533MHz. 
 
l Support for symmetric multiprocessing (SMP), which is available on systems with two Intel Xeon microprocessors. SMP greatly improves overall system 
performance by dividing microprocessor operations between independent microprocessors. To take advantage of this feature, you must use an 
operating system that supports multiprocessing. 
 
 
l A minimum of 256 MB of PC-266 registered DDR SDRAM memory modules, upgradable to a maximum of 8 GB by installing combinations of 128-MB, 256-
MB, 512-MB, 1-GB, or 2-GB 2-way interleaving memory modules in the four memory module sockets on the system board. 
 
l Support for up to three 1-inch, internal U320 SCSI hard drives (with hot-plug capability when using the optional ROMB card). 
 
l A single, 1.44-MB, 3.5-inch diskette drive. 
 
l An IDE CD or DVD drive. 
 
l Up to two hot-pluggable, 320-W power supplies in a 1 + 1 redundant configuration. 
 
l Seven hot-pluggable system cooling fans. 
 
The system board includes the following features: 
l A riser board assembly that supports up to two PCI expansion cards (two 3.3-V, 64-bit, 133-MHz PCI-X cards or one 3.3-V, 64-bit, 133-MHz PCI-X card 
and one 5-V, 64-bit, 33-MHz PCI card) 
 
l An integrated VGA-compatible video subsystem with an ATI RAGE XL video controller. This video subsystem contains 8 MB of SDRAM video memory 
(nonupgradable). Maximum resolution is 1600 x 1200 with 64,000 colors; 32-bit color depth is available for true-color graphics in the following 
resolutions: 640 x 480, 800 x 600, 1024 x 768, and 1280 x 1024. See the operating system documentation for additional supported video modes. 
 
l An integrated, dual-channel U320 SCSI host adapter. The internal channel supports up to three SCSI hard drives on the SCSI backplane. The SCSI 
backplane automatically configures SCSI ID numbers and SCSI termination, greatly simplifying drive installation. The second SCSI channel (an external 
SCSI channel) is available at the back of the system. 
 
l Optional ROMB through a separate RAID controller that incorporates 128 MB of cache memory and a RAID battery. 
 
l A Gigabit Ethernet PCI network card or two integrated Gigabit Ethernet NICs, capable of supporting 10-Mbps, 100-Mbps, and 1000-Mbps data rates. 
 
l Optional remote access controller (RAC) for remote system management. 
 
l Back-panel connectors include mouse, keyboard, serial, video, USB, external SCSI, RAC Ethernet, and two integrated NIC connectors.  
 
l Front-panel connectors include a video and a USB connector. 
 
For more information about specific features, see "Technical Specifications." 
Service Features 
The system includes the following service features to facilitate troubleshooting and repair: 
l Systems management circuitry that monitors operation of the system fans as well as critical system voltages and temperatures. The systems 
management circuitry works in conjunction with the systems management software. 
 
l System diagnostics for evaluating system components and devices. For information about using the system diagnostics, see "Running the System 
Diagnostics."  
 
NOTE: If you decide to upgrade your system by installing a second microprocessor, you must order the microprocessor upgrade kits from Dell. Not 
all versions of the Intel Xeon microprocessor will work properly as additional microprocessors. The upgrade kit from Dell contains the correct 
version of the microprocessor as well as the instructions for performing the upgrade. Both microprocessors must have the same internal operating 
frequency and cache size.
