viii BladeCenter TType 8720 and 8730: Hardware Maintenance Manual and Troubleshooting Guide

Chapter 1. General information
The IBM
® BladeCenter ®
TTypes 8720 and 8730 units are rack-mounted,
high-density, high-performance blade server systems developed for
telecommunications network applications and other applications requiring physical
robustness.
The BladeCenter Tunit uses blade servers, switches, and other components that
are common to the IBM BladeCenter product line. This common component
strategy makes it ideal for applications in telecommunications networks that need
high levels of computing power and access to common off-the-shelf middleware
packages that are used in IT data centers. The BladeCenter Tunit supports up to
eight blade servers and four I/O modules, making it ideally suited for networking
environments that require alarge number of high-performance servers in asmall
amount of space. The BladeCenter Tunit provides common resources that are
shared by the blade servers, such as power, cooling, system management, network
connections, backplane, and I/O (CD-ROM drive and connectors for USB, network
interfaces, and –for blade servers that support the KVM function –keyboard, video,
and mouse).
Performance, ease of use, reliability (NEBS/ETSI compliance), and expansion
capabilities were key considerations during the design of the BladeCenter Tsystem.
These design features make it possible for you to customize the system hardware
to meet your needs today, while providing flexible expansion capabilities for the
future.
This Hardware Maintenance and Troubleshooting Guide provides information to:
vSet up and cable aBladeCenter Tunit
vStart and configure aBladeCenter Tunit
vInstall and remove modules, options, and blades
vReplace field replaceable units
vPerform troubleshooting and servicing of the BladeCenter Tunit
Packaged with the Hardware Maintenance and Troubleshooting Guide are software
CDs that help you to configure and manage the BladeCenter Tunit.
This Hardware Maintenance and Troubleshooting Guide and other publications that
provide detailed information about your BladeCenter Tunit are provided in Portable
Document Format (PDF) on the IBM BladeCenter TDocumentation CD.
You can register the BladeCenter Tunit and blade servers on the World Wide Web.
To register, go to: http://www.ibm.com/pc/register/.
