Connecting External Devices
When connecting external devices to your system, follow these guidelines:
l Most devices must be connected to a specific connector and device drivers must be installed before the device operates properly. (Device drivers are
normally included with your operating system software or with the device itself.) See the documentation that accompanied the device for specific
installation and configuration instructions.
l Always attach external devices while your system is turned off. Next, turn on any external devices before turning on the system (unless the
documentation for the device specifies otherwise).
For information about individual connectors, see your Installation and Troubleshooting Guide. For information about enabling, disabling, and configuring I/O
ports and connectors, see " Using the System Setup Program ."
System Features
l One or two Intel Xeon microprocessors with an internal operating speed of at least 2.0 GHz, a level 2 cache of 512 KB, and a front -side bus operating
at 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 One of the following PCI expansion card slot options. Expansion card slots accommodate full-height, half-length expansion cards.
¡ Two connected riser cards that each have a 3.3-V, 64-bit, 133-MHz PCI-X expansion slot.
or
¡ Two connected riser cards, one with a 3.3-V, 64-bit, 133-MHz PCI-X expansion slot and one with a 5-V, 64-bit, 33-MHz PCI expansion slot.
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 1024 x 768 with 256 colors; 16.7 million colors are available for true-color graphics in the following resolutions:
640 x 480, 800 x 600, and 1024 x 768.
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 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 systems management.
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.
