About This Guide
This guide provides an overview of the architecture, general operation and descriptions of the
major components that compose the SGI®Integrated Compute Environment (ICE™) X series blade
enclosure systems. It also provides the standard procedures for powering on and powering off the
system, basic troubleshooting information, customer maintenance procedures and important
safety and regulatory specifications.
Audience
This guide is written for owners, system administrators, and users of SGI ICE X series computer
systems.
It is written with the assumption that the reader has a good working knowledge of computers and
computer systems.
Important Information
Warning: To avoid problems that could void your warranty, your SGI or other approved
service technician should perform all the setup, addition, or replacement of parts, cabling,
and service of your SGI ICE X series system, with the exception of the following items that
you can perform yourself:
• Using your system console or network access workstation to enter commands and perform
system functions such as powering on and powering off, as described in this guide.
• Removing and replacing power supplies andfans as detailed in this document.
• Adding and replacing disk drives in optional storage systems and using the operator’s panel
on optional mass storage.
