About This Guide

This guide provides an overview of the architecture and descriptions of the major components that compose the SGI® Altix® 3700 Bx2 family of servers. 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 SGI Altix 3700 Bx2 series computer systems. It is written with the assumption that the reader has a general knowledge of computers and computer systems.

Important Information

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 Altix 3700 Bx2 system, with the exception of the following items that you can perform yourself:

  • Using your system console and your L1 controller 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 CR-bricks) on the front panel of your system bricks.

  • Using the ESI/ops panel (operating panel) on the D–brick2.

  • Man pages (online)

    Man pages locate and print the titled entries from the online reference manuals.

You can obtain SGI documentation, release notes, or man pages in the following ways:

  • See the SGI Technical Publications Library at http://docs.sgi.com . Various formats are available. This library contains the most recent and most comprehensive set of online books, release notes, man pages, and other information.

  • The release notes, which contain the latest information about software and documentation in this release, are in a file named README.SGI in the root directory of the SGI ProPack for Linux Documentation CD.

  • You can also view man pages by typing man <title> on a command line.

SGI systems include a set of Linux man pages, formatted in the standard UNIX “man page” style. Important system configuration files and commands are documented on man pages. These are found online on the internal system disk (or CD-ROM) and are displayed using the man command. For example, to display the man page for the xscsidisktest command, type the following on a command line:

man xscsidisktest

References in the documentation to these pages include the name of the command and the section number in which the command is found.

For additional information about displaying man pages using the man command, see man(1).

In addition, the apropos command locates man pages based on keywords. For example, to display a list of man pages that describe disks, type the following on a command line:

apropos disk

For information about setting up and using apropos, see apropos(1).
