Introduction 1-1Chapter 1IntroductionDell ® PowerEdge ® 4200 systems are high-speed,upgradable PC servers designed around the Intel® Pen-tium® II family of microprocessors. The PowerEdge4200 systems provide both Extended Industry-StandardArchitecture (EISA) and high-performance PeripheralComponent Interconnect (PCI) expansion slots to allowfor future expansion of your system.This chapter describes the major hardware and softwarefeatures of your system, provides information about theindicators and controls on the computer’s front panel,discusses connecting external devices to the computer,and describes the system’s security features.System FeaturesYour system offers the following major features:• One or two Pentium II microprocessors that run at aninternal speed of 233, 266, or 300 megahertz (MHz)and an external speed of 66 MHz.The Intel microprocessor in your computer includesMMX ™ technology designed to handle complexmultimedia and communications software. Thismicroprocessor incorporates new instructions anddata types as well as a technique called SingleInstruction, Multiple Data (SIMD) that allows themicroprocessor to process multiple data elements inparallel, thereby improving overall systemperformance.• A secondary cache of 512 kilobytes (KB) of staticrandom-access memory (SRAM) is included withinthe single-edge contact (SEC) cartridge, which alsocontains the microprocessor. Math coprocessor func-tionality is internal to the microprocessor.• Support for symmetric multiprocessing when a sec-ond microprocessor is installed. Symmetricmultiprocessing greatly improves overall system per-formance by dividing microprocessor operationsbetween the two independent microprocessors. Totake advantage of this feature, you must use an operat-ing system that supports multiprocessing, such asMicrosoft® Windows NT ® 3.51 or 4.0, or Novell®NetWare® 4.11 SMP.NOTE: If you decide to upgrade your system byinstalling a second microprocessor, you must order amicroprocessor upgrade kit from Dell. Not all ver-sions of the Pentium II microprocessor will workproperly as a second microprocessor. The upgradekit from Dell contains the correct revision of themicroprocessor chip for use as a second micro-processor, as well as instructions for performing theupgrade. (A trained service technician must performthe upgrade.) The second microprocessor must havethe same internal operating frequency as the first.• A minimum of 64 megabytes (MB) of system mem-ory, upgradable to a maximum of 512 MB byinstalling combinations of 32- and 128-MB dual in-line memory modules (DIMMs) in the eight DIMMsockets on the system board. Fast-page mode andextended-data out (EDO) DIMMs are supported.The buffered, 72-bit-wide DIMMs installed inPowerEdge 4200 systems support error correctioncode (ECC) to check for and correct memory errors.ECC is performed by the memory controller in thesystem chip set.• An optional redundant, hot-pluggable power supplyand power supply paralleling board.• Three redundant system cooling fans.
