About This Guide

This guide provides an overview of the architecture and descriptions of the major
components that compose the SGI Origin 3900 server. It also provides the standard
procedures for powering on and powering off the system, basic troubleshooting
information, and important safety and regulatory specifications.
This guide is written for owners, system administrators, and users of the SGI Origin 3900
server. It is written with the assumption that the reader has a general knowledge of
computers and computer operations.
Warning:
To avoid problems, you must ask your SGI system support engineer (SSE)
to perform all the set up, addition or replacement of parts, cabling, and service of your
SGI Origin 3900 server, with the exception of the following items that you can perform
yourself:
• Using your system console and your L2 controller touch display to enter commands
and perform system functions such as powering on and powering off, as described
in this guide.
• Adding and replacing PCI and PCI-X cards, as described in this guide.
• Adding and replacing disk drives in the TP900 and D-brick2 storage modules, and
in the IX-brick, as described in this guide.
• Using the On/Off switch and other switches (the reset and non-maskable interrupt
[NMI] switches on the Cx-bricks) on the front panel of your system bricks.
• Using the ESI/ops panel (operating panel) on the D-brick2.
