Dell™ PowerEdge™ 1400 systems are high-speed, upgradable servers designed
around Intel
®
Pentium
®
III microprocessors. This document describes the major hard-
ware and software features of the system. It also provides information about the
indicators and controls on the computer's front panel and discusses connecting exter-
nal devices to the computer.

The system offers the following features:

One or two Intel Pentium III microprocessor(s).

Front side bus (FSB) with an external bus speed of 133 MHz.

A secondary cache of 256 kilobytes (KB) of static random-access memory
(SRAM). The secondary cache also provides error checking and correction (ECC)
capability.

Support for symmetric multiprocessing (SMP) when a second Pentium III micro-
processor is installed. SMP greatly improves overall system performance by
dividing microprocessor operations among the independent microprocessors. To
take advantage of this feature, you must use an operating system that supports
multiprocessing, Microsoft
®
Windows NT
®
Server 4.0, Windows 2000 Server,
Novell
®
NetWare
®
5.1, Red Hat Linux 6.2 Release SBE2 (and later versions), or
Microsoft BackOffice
®
Small Business Server (SBS) 4.5 (and later versions).
NOTES: If you decide to upgrade your system by installing a second microproces-
sor, you must order the microprocessor upgrade kit from Dell. Not all versions of
the Pentium III microprocessor will work properly as additional microprocessors.
The upgrade kit from Dell contains the correct version of the microprocessor for
use as a second microprocessor.
The second microprocessor must have the same internal operating frequency as
the first.

System memory that can be increased incrementally up to 2 gigabytes (GB)
using registered dynamic random-access memory (DRAM) dual in-line memory
modules (DIMMs). The memory subsystem also provides ECC capability, which
corrects all single-bit memory errors and detects all multibit errors.
