arnings, Cautions, and Notes
Throughout this manual, there may be blocks of text printed in bold type or in
italic type. These blocks are warnings, cautions, and notes, and they are used as
follows:
NOTE: A NOTE provides helpful information about using the computer system.
A prerequisite for using this manual to service Dell computer systems is a
basic knowledge of IBM®-compatible PCs and prior training in IBM-
compatible PC troubleshooting techniques. Moreover, only trained service
personnel should perform the procedures explained in this manual.
In addition to information provided in this manual and the User’s Guide that
came with the system, Dell provides the Installation and Troubleshooting
Guide for troubleshooting procedures and instructions on using the Dell di-
agnostics to test the computer system.
WARNING: A WARNING indicates the potential for bodily harm and
provides instructions for how to avoid the problem.
CAUTION: A CAUTION indicates either potential damage to hardware
or loss of data and provides instructions for how to avoid the problem.

System Overview 1-1
Chapter 1
System Overview
T
he Dell®PowerEdge®6100 system covered in this manual is a high-speed,
scalable, upgradable server system that uses the Intel®Pentium®Pro family of
microprocessors. PowerEdge 6100 systems incorporate the high-performance
PCI local bus as well as the EISA expansion bus. These buses are built into the
system board, which integrates the microprocessor(s) and other elements of the
basic computer system.
PowerEdge 6100 systems can have up to four Pentium Pro microprocessors.
The systems have been designed for better serviceability and increased reliabil-
ity, with optional redundant power supplies, RAID capability, hot-pluggable
SCSI hard-disk drives, thermal and power supply monitoring, redundant fans,
and ECC memory. The PowerEdge 6100 systems are freestanding or can be
rackmounted to integrate your servers. SIMMs and microprocessors are located
on modules that connect to the system board. Contact Dell for information
about Dell-supported microprocessor upgrades.
The Pentium Pro microprocessor contains a built-in clock multiplier circuit,
which increases the microprocessor’s internal operating frequency to a multiple
of the system clock frequency. The microprocessor’s internal speed for the Dell
PowerEdge 6100/200 system is 200 MHz derived from a system clock fre-
quency of 66 MHz.
S
ystem Features
In addition to the standard features found in a traditional personal computer,
Dell PowerEdge 6100 systems include the following new and/or advanced
features:
•512 KB of cache memory internal to each Pentium Pro microprocessor
•64 MB of DRAM main memory (standard), upgradable to 2 GB
•SCSI backplane board supporting up to six hard-disk drives (hot-pluggable
if PowerEdge Expandable RAID Controller is installed)
•Optional, redundant hot-pluggable power supplies
•ECC feature built in to the memory controller on the system board
•Advanced combination EISA and PCI expansion subsystem
•Six PCI and four EISA expansion-card slots (none shared)
•Integrated SVGA-compatible ISA video subsystem attached to the EISA
bus, with 1 MB video memory standard

1-2 Dell PowerEdge 6100/200 System Service Manual
•BIOS in upgradable flash memory attached to the EISA bus
•Integrated super I/O controller attached to the EISA bus, provides a
bidirectional parallel port, two serial ports, and the diskette drive interface
•Two integrated Ultra/Wide SCSI controllers
•Integrated server management circuitry that monitors critical system volt-
ages and temperatures, as well as the operation of the system cooling fans
•CD-ROM drive standard in an externally accessible drive bay
•Recessed power and reset buttons to prevent accidental system interruptions
All of these features are briefly described in this chapter. For a complete list of
system features, see “Technical Specifications” found later in this chapter.
For information about installing the PowerEdge 6100 systems in a rack, see the
“Dell PowerEdge 4100 and 6100 Systems Rack Kit Installation Guide”
(P/N 40722).
