Chapter 1. General information The IBM xSeries 235 Type 8671 is a high-performance server. It can be Eserver upgraded to a symmetric multiprocessing (SMP) server through a microprocessor upgrade. It is ideally suited for networking environments that require superior microprocessor performance, efficient memory management, flexibility, and large amounts of reliable data storage. Performance, ease of use, reliability, and expansion capabilities were key considerations in the design of your server. These design features make it possible for you to customize the system hardware to meet your needs today and provide flexible expansion capabilities for the future. This server contains IBM Enterprise X-Architecture™ technologies, which help increase performance and reliability. You can obtain up-to-date information about your server and other IBM server products at http://www.ibm.com/eserver/xseries/ on the World Wide Web. Note: The illustrations in this document might differ slightly from the hardware. Related publications This Hardware Maintenance Manual and Troubleshooting Guide is provided in Portable Document Format (PDF) on the IBM xSeries Documentation CD. It contains information to help you solve the problem yourself or to provide helpful information to a service technician. In addition to this Hardware Maintenance Manual and Troubleshooting Guide, the following xSeries 235 Type 8671 documentation is provided with your server: v User's Guide The User's Guide provides general information about the server, including information about features, how to configure the server, how to use the ServerGuide™ Setup and Installation CD, and how to get help. v Installation Guide This printed publication contains setup and installation instructions. v Rack Installation Instructions This printed publication contains the instructions to install your server in a rack. v Safety Information Book This multilingual publication is provided in PDF on the IBM xSeries Documentation CD. It contains translated versions of the caution and danger statements that appear in the documentation for your server. Each caution and danger statement has an assigned number, which you can use to locate the corresponding statement in your native language. v Option Installation Guide This publication is provided in PDF on the IBM xSeries Documentation CD.
