Overview

The Dell PowerEdge 4400, which has an Intel® Pentium® III Xeon™ microprocessor, is a feature-rich, enterprise class server that offers the highest performance, availability, scalability, manageability, and investment protection features. The PowerEdge 4400 includes a hot-pluggable 64-bit/66-megahertz (MHz) Peripheral Component Interconnect (PCI) bus, an integrated Ultra3 small computer system interface (SCSI), and an optional integrated redundant array of independent disks (RAID) with battery back-up cache. The PowerEdge 4400 provides a robust, reliable, rack-optimized platform on which large corporate customers can deploy their mission-critical applications. 

This section describes the major hardware and software features of the computer, provides information about the indicators and controls on the computer's front panel, and discusses connecting external devices to the computer.

System Features

PowerEdge 4400 systems offer the following major features:

• One or two Pentium III Xeon microprocessors.

The Processor Core option on Page 1 of the System Setup program lists your system's processor speed.  For more information, see "Using the System Setup Program."

The Pentium III Xeon microprocessor includes MMX™ technology designed to handle complex multimedia and communications software. This microprocessor incorporates new instructions and data types as well as a technique called single instruction, multiple data (SIMD) that allows the microprocessor to process multiple data elements in parallel, thereby improving overall system performance.

A secondary level 2 (L2) cache of static random-access memory (SRAM) is included within the single-edge contact (SEC) cartridge that contains the microprocessor. Math coprocessor functions are provided by the microprocessor. A separate and external math coprocessor chip is not used or required.

The size of the L2 cache is dependent on the processor installed in the system. The first screen of the System Setup program lists the system's cache size. For more information, see "Using the System Setup Program."

• Front side bus (FSB) with an external bus speed of 133 MHz.

• Support for symmetric multiprocessing (SMP) is available by installing a second Pentium III Xeon microprocessor. SMP greatly improves overall system performance by dividing microprocessor operations between the two independent microprocessors. To take advantage of this feature, you must use an operating system that supports multiprocessing, such as Microsoft® Windows NT® Server 4.0 or Novell® NetWare® 4.2 (and later versions).

NOTE: If you decide to upgrade your system by installing a second microprocessor, you must order a microprocessor upgrade kit from Dell. Not all versions of the Pentium III Xeon microprocessor work properly as a second microprocessor. The upgrade kit contains the correct version of the microprocessor for use as a second microprocessor as well as instructions for performing the upgrade.

• A minimum of 128 megabytes (MB) of system memory, upgradable to a maximum of 2 gigabytes (GB) by installing combinations of 64-, 128-, or 256-MB registered synchronous dynamic RAM (SDRAM) dual in-line memory modules (DIMMs) in the eight DIMM sockets on the system board. These DIMMs must be installed in equal pairs.

• A basic input/output system (BIOS) that resides in flash memory on the PCI bus that can be upgraded if required.

• Eight 1-inch or six 1.6-inch, hot-pluggable, SCSI hard-disk drives.
  

• Two additional 1-inch drives can be installed in the optional removable media bay via a 1 x 2 SCSI backplane board. If this backplane is configured as a split backplane using two SCSI cable connections, these two drives are hot-pluggable.

• A power-supply distribution board to accommodate up to three independent power supplies. Two power supplies are standard; a third can be added to make the system redundant.
  

• Redundant, hot-pluggable fans that run independently.
  
  
• A single, 1.44-MB 3.5-inch diskette drive.
  
  
• A 17/40x SCSI CD-ROM drive.

The system board includes the following integrated features:

• Seven PCI slots located on the system board. PCI slots 1 through 4 are hot-pluggable. PCI slots 1 and 2 are 64-bit, 66-MHz PCI slots; PCI slots 3 through 6 are 64-bit, 33-MHz PCI slots. Slot 7 provides a 32-bit, 33-MHz PCI slot for use with the optional Dell OpenManage™ Remote Assistant Card (DRAC) or other PCI accessories.
  
  
• An integrated Intel PRO/100+ network interface controller (NIC), which provides an Ethernet interface and failover and load balancing with single and dual ports.
  
  
• An integrated Adaptec AIC-7899 dual-channel Ultra3 SCSI host adapter that supports up to ten SCSI hard-disk drives (eight 1-inch hard-disk drives via a SCSI backplane board and two 1-inch hard-disk drives via an external SCSI hard-disk drive media bay). The SCSI backplane automatically configures SCSI ID numbers and SCSI termination on individual hard-disk drives, greatly simplifying drive installation. 
  
  
• An integrated PowerEdge Expandable RAID Controller (PERC) 3/Di that supports RAID levels 0, 1, 5, and 10. The Ultra3 SCSI host adapter can become RAID capable with the addition of the PERC 3/Di hardware enable kit.
  
  
• An integrated Adaptec AIC-7880 Ultra/Wide SCSI secondary host adapter (implemented as Ultra/Narrow) that supports up to three externally accessible SCSI devices in the external hard-disk drive bays (for example, CD-ROM drive, tape drive unit).
  
  
• An integrated video graphics array (VGA)-compatible video subsystem with an ATI RAGE IIC video controller. This video subsystem contains 4 MB of synchronous dynamic RAM (SDRAM) video memory (nonupgradable). Maximum resolutions are 1600 x 1200 x 65K colors (noninterlaced). The maximum true-color resolution is 1152 x 864; 16.7 million colors are available for true-color graphics.
  
  
• An integrated National Semiconductor PC97317 super input/output (I/O) controller that controls the bidirectional parallel port, two serial ports, keyboard, mouse, and the diskette drive in the externally accessible front bay.
  
  

The parallel port can be set to operate in the following modes via the Parallel Mode option in the System Setup program: output-only (AT-compatible), bidirectional (Personal System/2 [PS/2]-compatible).



• Integrated server management circuitry that monitors operation of the system fans as well as critical system voltages and temperatures. The integrated server management circuitry works in conjunction with the optional HP OpenView Network Node Manager Special Edition (NNM SE) and the Dell OpenManage Hardware Instrumentation Package (HIP) software package.
  
  
• System board support for the Dell OpenManage Remote Assistant when the optional DRAC 2 is installed, which provides additional local and remote server management.
  
  
• A PS/2-style keyboard port, dual Universal Serial Bus (USB) ports, and a PS/2-compatible mouse port.

Standard PowerEdge 4400 systems include a 3.5-inch diskette drive and a SCSI CD-ROM drive installed in the externally accessible bays and a SCSI hard-disk drive installed in slot 0.
