IBM Enterprise X-Architecture
™
technologies
1
.
Your BladeCenter HS20 blade server can be installed in an IBM Eserver
BladeCenter Type 8677 unit or IBM Eserver BladeCenter T Types 8720 and 8730
units.
Note: Unless otherwise stated, references to the BladeCenter unit also apply to the
BladeCenter T unit.
These high-performance blade servers are ideally suited for networking
environments that require superior microprocessor performance, efficient memory
management, flexibility, and reliable data storage.
This Installation and User’s Guide provides information to:
v Set up the blade server
v Start and configure the blade server
v Install options
v Install the operating system
v Perform basic troubleshooting of the blade server
Packaged
with the Installation and User’s Guide are software CDs that help you to
configure hardware, install device drivers, and install the operating system. To
download the latest device drivers, go to the IBM Support Web site at
http://www.ibm.com/pc/support/.
The blade server comes with a limited warranty. For information about your
warranty, see, Appendix B, “IBM Statement of Limited Warranty Z125-4753-07
11/2002,” on page 71. You can obtain up-to-date information about your
BladeCenter HS20 Type 8832 model and IBM xSeries
®
server products at
http://www.ibm.com/eserver/xseries/.
You can register the blade server at http://www.ibm.com/pc/register/.
Record information about your BladeCenter HS20 blade server in the following
table.
Note: The model number and serial number are on the ID label that is behind the
control panel door on the front of the blade server, and on a label on the
right side of the blade server that is visible when the blade server is not in
the BladeCenter unit. You will need these numbers when you register your
blade server with IBM.
1. Enterprise X-Architecture technology takes full advantage of existing IBM technologies to build powerful, scalable, and reliable Intel
processor-based servers. For more information about IBM Enterprise X-Architecture, go to

Note:
″Short term″ refers to a period
of not more than 96 consecutive hours
and a total of not more than 15 days in
1 year. (This refers to a total of 360
hours in any given year, but no more
than 15 occurrences during that 1-year
period.)
Note: The operating system in the blade server must provide USB support for the
blade server to recognize and use the keyboard, mouse, CD-ROM drive, and
an external diskette drive. The BladeCenter T unit uses USB for internal
communications with these devices.
