Dell® PowerEdge® 2300 systems are high-speed, upgradable server systems designed around the Intel® Pentium® II family of microprocessors. The PowerEdge 2300 systems provide both high-performance Peripheral Component Interconnect (PCI) and Industry-Standard Architecture (ISA) expansion slots to allow for future expansion of your system. This chapter 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. The PowerEdge 2300 systems offer the following major features: One or two Intel Pentium II microprocessors with an internal operating frequency of 333, 350, or 400 megahertz (MHz) and an external bus speed of 66 MHz (333-MHz processor) or 100 MHz (350- and 400-MHz processors). The Pentium II 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 (L2) cache of 512 kilobytes (KB) of static random-access memory (SRAM) is included within the single-edge contact (SEC) cartridge that contains the microprocessor. Math coprocessor functionality is internal to the microprocessor. Support for symmetric multiprocessing is available by installing a second Pentium II 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® 4.0 or Novell® NetWare® 4.11 (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 II microprocessor will work properly as a second Introduction 1-1

The PowerEdge 2300 systems offer the following major features:
²
One or two Intel Pentium II microprocessors with an internal operating frequency
of 333, 350, or 400 megahertz (MHz) and an external bus speed of 66 MHz (333-MHz
processor) or 100 MHz (350- and 400-MHz processors).
The Pentium II microprocessor includes MMX
™
technology designed to handle
complex multimedia and communications software. This microprocessor incorpo-
rates new instructions and data types as well as a technique called Single
Instruction, Multiple Data (SIMD) that allows the microprocessor to process mul-
tiple data elements in parallel, thereby improving overall system performance.
²
A secondary (L2) cache of 512 kilobytes (KB) of static random-access memory
(SRAM) is included within the single-edge contact (SEC) cartridge that contains
the microprocessor. Math coprocessor functionality is internal to the
microprocessor.
²
Support for symmetric multiprocessing is available by installing a second Pentium II
microprocessor. Symmetric multiprocessing greatly improves overall system per-
formance by dividing microprocessor operations between the two independent
microprocessors. To take advantage of this feature, you must use an operating sys-
tem that supports multiprocessing, such as Microsoft
®
Windows NT
®
4.0 or
Novell
®
NetWare
®
4.11 (and later versions).
NOTE: If you decide to upgrade your system by installing a second micro-
processor, you must order a microprocessor upgrade kit from Dell. Not all
versions of the Pentium II microprocessor will work properly as a second
