Indicator

Function

Power supply status Green indicates that the power supply is operational.

Power supply fault

Amber indicates a problem with the power supply.

AC line status

Green indicates that a valid AC source is connected to the power supply.

System Features

One or two Intel Xeon processors with an internal operating speed of at least 2.8 GHz, a level 2 cache of at least 1 MB, and a front-side bus operating

at 800 MHz.

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.

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, heat sink, and fan(s) as well as the instructions for performing the upgrade. Both microprocessors must have the

same internal operating frequency and cache size.

A minimum of 256 MB of registered PC2-3200 DDR 2 400 SDRAM memory modules, upgradable to a maximum of 16GB (if supported by the operating

system) by installing combinations of 256-MB, 512-MB, 1-GB, 2-GB, or 4-GB (when available) 2-way interleaving memory modules in the six memory

module sockets on the system board.

NOTE:

Two-way interleaving is not supported in the 256 MB single memory configuration.

The system also features redundant memory, which provides a failover memory bank of memory mirroring. The failover memory bank (spare bank) is

available if all banks (six memory modules) are populated with identical memory modules. The memory mirroring feature is available only if banks 1 and 2

(four memory modules) are populated with identical memory modules.

Support for up to six 1-inch, internal U320 SCSI hard drives (with hot-plug capability when using the optional RAID capability). An optional daughter card

provides support for a split backplane.

An optional single, 1.44-MB, 3.5-inch diskette drive.

An optional IDE CD or DVD drive.

Up to two hot-pluggable, 700-W power supplies in a 1 + 1 redundant configuration.

Up to six redundant system cooling fans.

The system board includes the following features:

One of the following riser card options:

A riser card cage that has three 3.3-V, 64-bit, 133MHz PCI-X expansion slots, and RAID on motherboard (ROMB). Expansion card slots

accommodate full-height, one half-length and 2 full-length expansion cards.

A riser card cage that has one x4 lane-width and one x8 lane-width, PCI-Express expansion slots, one 3.3-V, 64-bit, 100-MHz PCI-X expansion

slot, and ROMB. Expansion card slots accommodate half-length expansion cards.

An integrated, dual-channel U320 SCSI host adapter. The internal channel supports up to six SCSI hard drives on the SCSI backplane. The SCSI

backplane automatically configures SCSI ID numbers and SCSI termination, greatly simplifying drive installation.

Optional RAID through a separate controller card that incorporates 128 MB of cache memory and a RAID battery.

Two integrated Gigabit Ethernet NICs, capable of supporting 10-Mbps, 100-Mbps, and 1000-Mbps data rates.

Four USB 2.0-compliant connectors (two on the front and two on the back) capable of supporting a diskette drive, a CD-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 Radeon 7000-M, 33MHz PCI video controller. This video subsystem contains 16MB of SDRAM

video memory (nonupgradable). Maximum resolution is 1600 x 1200 with 64,000 colors; true-color graphics are supported in the following resolutions:
