About This Guide
This guide describes how to set up and operate a Silicon GraphicsOrigin200™server. It
contains the following chapters:
• Chapter 1, “Overview of the Origin200 System,” provides an overview of the
Origin200 system, including the main system features, internal components,
external connectors, and physical specifications of the machine.
• Chapter 2, “Setting Up an Origin200 System,” describes how to set up a
one-module or two-module Origin200 system. It shows how to open and close the
chassis, how to attach a system console, how to connect two Origin200 modules
together, how to turn on the system, how to log in for the first time, and how to turn
the system off.
• Chapter 3, “Installing an Origin200 System in a Rack,” describes how to install a
one-module or two-module Origin200 system in a rack cabinet.
• Chapter 4, “Using the Origin200 System,” documents common tasks in operating
the server, including turning the system on and off, using the front panel buttons
(reset, nonmaskable interrupt), using the AUX port and the system controller, and
how to open the system chassis for servicing.
• Chapter 5, “Installing and Removing Memory,” describes how to install and remove
dual-inline memory modules (DIMMs) in an Origin200 module.
• Chapter 6, “Installing and Removing PCI Option Boards,” shows how to install
peripheral component interconnect (PCI) option boards in an Origin200 module.
• Chapter 7, “Installing and Configuring Peripherals,” describes how to attach
various internal and external peripherals to an Origin200 module. These include
disk drives, tape drives, CD-ROM drives, and serial devices.
• Chapter 8, “Troubleshooting,” lists the message codes for the system status LED,
Ethernet port LEDs, and drive status LEDs, and describes how to check the power
supply.
• Chapter 9, “Replacing Internal Parts,” shows how to remove components from an
Origin200 module, order replacement parts, and install replacement parts.

About This Guide
In addition, this guide contains the following appendices:
• Appendix A, “Connector Pinout Assignments,” shows the pinouts of the various
connectors available on the Origin200 system.
• Appendix B, “Cable Descriptions,” describes various cables that can be used with
the Origin200 system, including serial, Ethernet, SCSI, parallel, and CrayLink™
Interconnect.
• Appendix C, “Supported Terminals,” lists some common terminal types that are
supported by IRIX™on the Origin200 system.

Origin200 Owner’s Guide
Refer to the Origin200 Owner’s Guide (this manual) to set up the system, use the system,
install hardware options, and whenever you suspect there is a hardware problem. In
addition, you can refer to this guide when you install or remove optional software.
The system and all the procedures in this guide are designed so that you may maintain
manyofthecomponentsofthesystemwithoutthehelpofatrainedtechnician.However,
do not feel that you must work with the hardware yourself. You can always contact your
maintenance provider to have an authorized service provider work with the hardware
instead.
Optional Documentation
The IRIX Admin manual set is recommended as a reference for system administration
tasks. This set of manuals contains the following books:
•IRIX Admin: Software Installation and Licensing—This book explains how to install
and license software that runs under IRIX, the Silicon Graphics implementation of
the UNIXoperating system. It contains instructions for performing miniroot and
live installations using Inst, the command-line interface to the IRIX installation
utility. It also identifies the licensing products that control access to restricted
applications running under IRIX and refers readers to licensing product
documentation.
•IRIX Admin: System Configuration and Operation—This book lists good general
system administration practices and describes system administration tasks,
