  Technical Specifications

Your system is a high-performance enterprise server offering new levels of performance and scalability with up to four Intel® Xeon™ microprocessors and 16 GB of system memory, as well as hot-pluggable hard drives, expansion slots, power supplies, and system fans.

This section describes the major hardware and software features of your system. It also provides information about other documents you may need when setting up your system and how to obtain technical assistance.

CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. See your System Information document for complete safety information.

System Features

• Up to four Intel Xeon microprocessors with an internal operating speed of at least 1.40 GHz; an L2 cache of 256 KB and an L3 cache of 512 KB or 1 MB (L2 and L3 cache size is dependant on microprocessor speed); and a front-side (external) bus speed of 400 MHz.
  
  
• Support for SMP, which is available on systems with at least two 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 an additional microprocessor, you must order the microprocessor upgrade kits from the company where you purchased your system. Not all versions of the Intel Xeon microprocessor will work properly as additional microprocessors. The upgrade kit contains the correct version of the microprocessor as well as the instructions for performing the upgrade. All microprocessors must have the same internal operating frequency and cache size.

• A minimum of 512 MB of system memory, upgradable to a maximum of 16 GB by installing combinations of DDR SDRAM memory modules in the 16 memory module sockets. The memory module sockets are located on two riser cards with eight sockets per card.
  
  

NOTE: All memory modules in a single memory bank must be the same size and type.

The system also features redundant memory, which provides your system with a failover memory bank when a memory bank fails, and a memory mirror, which splits the four memory banks into a mirrored set.

NOTE: Spare bank memory is supported if three or four identical memory banks (12 or 16 memory modules) are installed on your system. Memory mirror is supported if four identical banks (16 memory modules) are installed on your system. Both features must be enabled/disabled in the BIOS setup. You cannot enable both features simultaneously. For more information, see "Using the System Setup Program."

• Support for up to five 1-inch, internal Ultra3 SCSI hard drives connected to a hot-pluggable SCSI backplane (the backplane can be split into 2+3).
  
  
• 1 MB flash for the system BIOS, video BIOS, and SCSI BIOS.
  
  
• A single, 1.44-MB, 3.5-inch diskette drive.
  
  
• A 24X IDE CD or DVD drive.
  
  
• Two hot-pluggable, 900-W power supplies in a 1 + 1 redundant configuration.
  
  
• Six redundant, hot-pluggable system cooling fans.
  
  
• An intrusion switch that signals the appropriate systems management software if the top cover is opened.
  
  
• Eight hot-pluggable expansion slots (seven full-length, 64-bit, 100-MHz PCI or PCI-X slots and one 32-bit, 33-MHz PCI slot).
  
  
• An integrated VGA-compatible video subsystem with an ATI RAGE XL video controller. This video subsystem contains 8 MB of SDRAM video memory (nonupgradable). The maximum resolution is 1600 x 1200 with 256 colors.
  
  
• An integrated, single-channel Ultra3 SCSI controller for internal SCSI hard drives or tape drives.
  
  
• An optional dual- or quad-channel RAID controller card for connection to both internal and external storage.
  
  
• Optional remote access card that provides remote management capabilities for your system. The remote access card allows you to manage and monitor your system through a modem or network connection, even when the system itself is down.
  
  
• Two integrated 10/100/1000 Mbps NICs, which provide an Ethernet interface.
  
  
• Embedded 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 your systems management software.
  
  
• Back-panel connectors include mouse, keyboard, serial, video, two USB, external SCSI, and two NIC connectors.
  
  

For more information about specific features, see "Technical Specifications."

Software Features

• A System Setup program for quickly viewing and changing system configuration information. For more information on this program, see "Using the System Setup Program."
  
  
• Enhanced security features, including a system password and a setup password, available through the System Setup program (see "Using the System Setup Program").
  
  
• System diagnostics for evaluating system components and devices. For information on using the system diagnostics, see "Running the System Diagnostics."
  
  
• Video drivers for displaying many popular application programs in high-resolution modes.
  
  
• SCSI device drivers that allow the operating system to communicate with devices attached to the integrated SCSI subsystem. For more information on these drivers, see "Installing and Configuring SCSI Drivers" in your User's Guide.
  
  
• Systems management software and documentation CDs.
  
  

Supported Operating Systems

• Microsoft® Windows NT® Server 4.0
  
  
• Windows NT Server 4.0, Terminal Server
  
  
• Windows NT Server 4.0, Enterprise Edition
  
  
• Microsoft Windows® 2000 Server and Advanced Server
  
  
• Red Hat Linux 7.2 or later
  
  
• Novell® NetWare® 6.0
  
  

Service Features

The system includes the following service features to make troubleshooting and repair easy and effective, in most cases without tools or service aids:

• System diagnostics are available on the utility partition, which checks for hardware problems (if the system can boot). You can also install the diagnostics onto diskettes from the Dell OpenManage Server Assistant CD.
  
  
• Optional systems management hardware and software, which monitors temperatures and voltages throughout the system and notifies you if the system overheats, if a system cooling fan malfunctions, if a processor overheats, or if a power supply or VRM fails. For information about the systems management option, see your systems management software documentation.
  
  
• The system chassis simplifies removing and replacing system components. You can replace microprocessors or memory modules without removing the system board. The SCSI backplane board and hard-drive carriers eliminate the extensive cabling and drive configuration usually required for a SCSI subsystem.
  
  

Power Protection Devices

A number of devices are available to protect your system from the effects of power problems such as power surges, transients, and power failures. The following subsections describe some of these devices.

Surge Protectors

Surge protectors are available in a variety of types and usually provide a level of protection commensurate with the cost of the device. Surge protectors prevent overvoltage spikes, such as those that may occur during an electrical storm, from entering the system through the electrical outlet. Surge protectors do not offer protection against brownouts, which occur when the voltage drops more than 20 percent below the normal power line voltage level.

Line Conditioners

Line conditioners go beyond the overvoltage protection of surge protectors. Line conditioners keep a system's power source voltage at a fairly constant level and provide protection from brownouts of short duration. Because of this added protection, line conditioners cost more than surge protectors—up to several hundred dollars. However, these devices cannot protect against a complete loss of power.

Uninterruptible Power Supplies

UPS systems offer the most complete protection against variations in power because they use battery power to keep the system running when power is unavailable or unusable. The battery is charged by the AC power while it is available so that once power is lost, the battery can provide power to the system for a limited amount of time—from 15 minutes to an hour or so—depending on the UPS system.

UPS systems range in price from a few hundred dollars to several thousand dollars, with the more expensive units allowing you to run larger systems for a longer period of time when power is lost. UPS systems that provide only 5 minutes of battery power let you conduct an orderly shutdown of the system but are not intended to provide continued operation. Surge protectors should be used with all UPS systems, and the UPS system should be UL safety approved.
