Introduction: Dell™PowerEdge™4400SystemsUser'sGuide
Overview
The Dell PowerEdge 4400, which has an Intel®Pentium®IIIXeon™microprocessor,isafeature-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)PeripheralComponentInterconnect(PCI)bus,anintegratedUltra160/msmallcomputersysteminterface(SCSI),and
an optional integrated redundant arrays 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-criticalapplications.
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:
l One or two Pentium III Xeon microprocessors.

"Using the System Setup Program."
ThePentiumIIIXeonmicroprocessorincludesMMX™technologydesignedtohandlecomplexmultimediaandcommunications
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
thatcontainsthemicroprocessor.Mathcoprocessorfunctionsareprovidedbythemicroprocessor.Aseparateandexternalmath
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."
l Front side bus (FSB) with an external bus speed of 133 MHz.
l Support for symmetric multiprocessing is available by installing a second Pentium III Xeon microprocessor. Symmetric multiprocessing
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).
l A minimum of 128 megabytes (MB) of system memory, upgradable to a maximum of 4 gigabytes (GB) by installing combinations of 64-,
128-, 256-, or 512 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.
l A basic input/output system (BIOS) that resides in flash memory on the PCI bus that can be upgraded if required.
l Eight 1-inch or six 1.6-inch, hot-pluggable, SCSI hard-disk drives.
l 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.
l 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.
l Redundant, hot-pluggable fans that run independently.
