About This Guide
This guide provides an overview of the SGI Origin 350 server system components. It also
describes how to set up and operate the Origin 350 server system.
The Origin 350 server system is either a standalone base compute module, or a base
compute module connected and rackmounted with the following optional modules that
expand the function of the system:
• A system expansion compute module, which is interconnected to the base compute
module via a NUMAlink 3 cable, adds processors, memory, and PCI/PCI-X card
slots, but may or may not have an IO9 card. (The new single system created by
connecting the two modules together can include 4, 6, or 8 processors with local
memory of up to 16 GB.)
• A 2U memory and PCI expansion (MPX) module provides extra memory and four
PCI and PCI-X card slots to your system. See Chapter 4, “Memory and PCI
Expansion (MPX) Module,” for information about this module.
• The 4U PCI expansion module adds PCI slots, but no processors, no memory, and
no IO9 card. There are two versions of the PCI expansion module: one module has
12 PCI slots that support 3.3-V or universal PCI cards, and the other module has 6
PCI slots that support 5-V or universal PCI cards and 6 slots that support 3.3-V or
universal PCI cards. For information about this module, see PCI Expansion Module
User’s Guide (5.0-V Support and/or 3.3-V Support) (007-4499-00x).
• The SGI TP900 storage module provides additional storage to the system. For
information about this module, see SGI Total Performance 900 Storage System User’s
Guide (007-4428-00x). The Origin 350 server supports other storage modules. See
“Storage Expansion” on page 89 for information.
• The NUMAlink module connects two or more compute modules in your server
system. See Chapter 5, “NUMAlink Module,” for information about this module.
This guide is written for owners, system administrators, and users of the Origin 350
server system. It is written with the assumption that the reader has a general knowledge
of computers and computer operations.

About This Guide
Important Information
Your SGI system support engineer (SSE) should perform the addition or replacement of
parts, cabling, and service of your Origin 350 server system, with the exception of the
following tasks that you may perform yourself:
• Installing your system in a rack.
• Cabling the system modules to each other.
• Connecting a system console to your server system.
• Using your system console to enter commands and perform system functions such
as powering on and powering off.
• Using the On/Off, reset, and non-maskable interrupt (NMI) switches on the front
panel of your server system.
• Installing and removing PCI and PCI-X cards.
Caution: Exception: Because the installation and removal of an IO9 PCI card, which
installs in the lowermost slot, is more complicated and can cause damage to your
system if not performed properly, it can only be installed and removed by a trained
SGI system support engineer.
• Installing and removing disk drives.
• Installing and removing power supplies.
• Installing and removing DIMMs.
• Installing and removing the L1 controller display.
Chapter Descriptions
The following topics are covered in this guide:
• Chapter 1, “Installation and Operation,” provides instructions for rack mounting,
cabling, and operating the Origin 350 server system.
• Chapter 2, “System Overview,” provides a general overview of the Origin 350
server system, including a list of the system features. This chapter also includes a
quick description of the various components and modules that can be part of an
Origin 350 server system.
