What your BladeCenter unit offers
The design of your BladeCenter unit takes advantage of advancements in server
technology. It provides up to 14 functionally separate servers and their shared
resources in a single center. Your BladeCenter unit combines:
v IBM Enterprise X-Architecture technology
IBM Enterprise X-Architecture technology leverages proven innovative IBM
technologies to build powerful, scalable, reliable Intel-processor-based servers.
Enterprise X-Architecture technology includes features such as Predictive Failure
Analysis (PFA), scalability, and Real Time Diagnostics.
v Expansion capabilities
You can add blade servers to the BladeCenter unit as needed, up to a maximum
of 14 blade servers.
Note: When any blade server or option is in blade bay 7 through 14, power
modules must be present in power bays 1 and 2, and power modules
must be present in power bays 3 and 4.
Some blade servers have connectors for options that add capabilities to the
blade server, such as an I/O expansion card to add a network interface, or a
storage expansion unit to add SCSI hard disk drives.
v Hot-swap capabilities
The front bays on the BladeCenter unit are hot-swap blade bays; the rear bays
on the BladeCenter unit are hot-swap module bays. You can add, remove, or
replace blade servers or management, I/O, power, or blower modules in
hot-swap bays without removing power from the BladeCenter unit.
Attention: To maintain proper system cooling, each unoccupied bay must
contain a filler blade or filler module.
Chapter 1. Introduction 7
v Redundancy capabilities
The redundant components in the rear of your BladeCenter unit enable continued
operation if one of the components fails.
– Power modules and blowers: Normally, the redundant power modules and
blowers share the load. If one of the power modules or blowers fails, the
non-failing power module or blower handles the entire load. You can then
replace the failed blower or power module without shutting down the
BladeCenter unit.
– Management modules: Only one management module will be active at a time.
If the active management module fails, the secondary, or redundant,
management module becomes the active management module, containing
current BladeCenter configuration and status information. You can then
replace the failed management module without shutting down the BladeCenter
unit.
v Redundant network connection capabilities
Configuring a pair of Ethernet switch modules in I/O-module bays 1 and 2
identically provides support for Ethernet failover configured on blade servers. See
“Configuring a switch module” on page 46 for more information. If the I/O
expansion options in your blade servers can be configured for failover,
configuring a pair of switch modules in I/O-module bays 3 and 4 identically
provides support for the failover configured on the I/O expansion options.
Other network-interface I/O expansion options, such as the IBM HS20 Fibre
Channel Expansion Card, can have similar capability for redundant network
connections. See the documentation that comes with your I/O expansion and
switch module options for more information about configuring for redundant
network connections.
v System-management capabilities
Your BladeCenter unit comes with a service processor in the management
module. This service processor, in conjunction with the system-management
firmware that is provided with your BladeCenter unit and the service processor in
each blade server, enables you to remotely manage the BladeCenter unit, its
components, and the blade servers. The management module also multiplexes
the keyboard, mouse, and video ports and the USB port across the multiple
blade servers.
The service processor in each blade server provides blade server system
monitoring, event recording, and alert capability.
See Chapter 4, “Configuring your BladeCenter unit”, on page 37 for more
information.
v Network environment support
Your BladeCenter unit supports up to two Ethernet-compatible I/O modules
(switch modules or pass-thru modules), for blade server integrated Ethernet
controller communication with the network. Each I/O module provides one
internal connection to each blade server, up to 14 internal connections per I/O
module.
The BladeCenter unit also supports two additional I/O modules, for a total of four
I/O modules. The two additional I/O modules support the network interface on the
optional I/O expansion card installed on one or more blade servers in the
BladeCenter unit.
Note: The two additional I/O modules must be compatible with the network
interface on the optional I/O expansion cards in the blade servers.
8 BladeCenter Type 8677: Installation and User’s Guide
Each of these two additional I/O modules provides one internal connection to the
optional I/O expansion card, up to 14 internal connections per I/O module.
Reliability, availability, and serviceability
Three of the most important features in server design are reliability, availability, and
serviceability (RAS). These factors help to ensure the integrity of the data stored on
your blade server; that your blade server is available when you want to use it; and
that should a failure occur, you can easily diagnose and repair the failure with
minimal inconvenience.
The following is a list of some of the RAS features that your BladeCenter unit
supports:
v Shared key components, such as power, cooling, and I/O
v All components serviced from the front or rear of the chassis

Chapter 2. Installing options
This chapter provides instructions for adding options to your BladeCenter unit.
Some option-removal instructions are provided in case you need to remove one
option to install another.
Installing the BladeCenter unit in a rack
Statement 20:
CAUTION:
To avoid personal injury, before lifting the unit, remove all the blades to
reduce the weight.
Statement 4:
≥ 18 kg (39.7 lb) ≥ 32 kg (70.5 lb) ≥ 55 kg (121.2 lb)
CAUTION:
Use safe practices when lifting.
Install the BladeCenter unit in a rack before installing any blade servers in the
BladeCenter unit. If your BladeCenter unit has blade servers already installed,
remove them first. Blade servers are installed from the front of the BladeCenter unit,
without sliding the BladeCenter unit into or out of the rack. Detailed instructions for
installing a BladeCenter unit in a rack are in the Rack Installation Instructions that
come with your BladeCenter unit.
Installation guidelines
Before you begin to install options in your BladeCenter unit, read the following
information:
v Read the safety information beginning on page vii and the guidelines in “Handling
static-sensitive devices” on page 14. This information will help you work safely
with your BladeCenter unit and options.
v The orange color on components and labels in your BladeCenter unit identifies
hot-swap components. You can install or remove hot-swap modules and, with
© Copyright IBM Corp. 2002, 2003 13
some restrictions, hot-swap blade servers while the BladeCenter unit is running.
For complete details about installing or removing a hot-swap component, see the
detailed information in this chapter.
v The blue color on components and labels identifies touch points where you can
grip a component, move a latch, and so on.
v You do not need to disconnect the BladeCenter unit from power to install or
replace any of the hot-swap modules on the rear of the BladeCenter unit. You
need to shut down the operating system and turn off a hot-swap blade server on
the front of the BladeCenter unit before removing the blade server, but you do
not need to shut down the BladeCenter unit itself.
v For a list of supported options for your BladeCenter unit, go to
http://www.ibm.com/pc/compat/ on the World Wide Web.
System reliability considerations
To help ensure proper cooling and system reliability, make sure that:
v Each of the module bays on the rear of the BladeCenter unit has either a module
or filler module installed.
v Each of the blade bays on the front of the BladeCenter unit has either a blade
server or filler blade installed.
v Each of the drive bays in a blade server storage expansion option has either a
hot-swap drive or a filler panel installed.
v A removed hot-swap module, blade server, or drive is replaced within 1 minute of
removal.
v Cables for the option modules are routed according to the illustrations and
instructions in this document.
v A failed blower is replaced as soon as possible, to restore cooling redundancy.
Handling static-sensitive devices
Attention: Static electricity can damage electronic devices and your system. To
avoid damage, keep static-sensitive devices in their static-protective packages until
you are ready to install them.
To reduce the possibility of electrostatic discharge, observe the following
precautions:
v Limit your movement. Movement can cause static electricity to build up around
you.
v Handle the device carefully, holding it by its edges or its frame.
v Do not touch solder joints, pins, or exposed printed circuitry.
v Do not leave the device where others can handle and damage it.
v While the device is still in its static-protective package, touch it to an unpainted
metal part of the system unit for at least 2 seconds. This drains static electricity
from the package and from your body.
v Remove the device from its package and install it directly into the system unit
without setting the device down. If it is necessary to set down the device, place it
back into its static-protective package. Do not place the device on your system
unit or on a metal surface.
v Take additional care when handling devices during cold weather. Heating reduces
indoor humidity and increases static electricity.

Installing and removing modules
The procedures for installing or removing a module on the BladeCenter unit are
nearly identical for all modules except the blower modules. To install or remove a
blower module, see the BladeCenter Hardware Maintenance Manual and
Troubleshooting Guide on the BladeCenter Documentation CD. To install or remove
all other modules, follow the instructions in this section.
Each module is keyed so that it can be inserted only in an appropriate bay. You can
insert an I/O module only in an I/O-module bay, for example. In addition, most
modules must be installed in a specific sequence or under specific circumstances.
The BladeCenter modules
Your BladeCenter unit contains the following hot-swap modules: power modules, I/O
modules, management modules, and blower modules. See “Rear view” on page 33
for the location of each module. These modules supply common functions to the
blade servers that are installed in the blade bays in the front of the BladeCenter
unit.
The chassis and the active management module supply I/O (diskette drive,
CD-ROM drive, USB port, keyboard, video, and mouse) that is available to all the
blade servers, selected by any one blade server at a time. The chassis can contain
up to 14 blade servers.
Attention: To help ensure proper cooling, performance, and system reliability,
make sure that each of the module bays on the rear of the BladeCenter unit has a
module or filler module installed. When replacing a module, do not operate the
BladeCenter unit for more than one minute without either a module or a filler
module installed in each module bay.
Management module
Your BladeCenter unit comes with one hot-swap management module in the
management bay. You can add a management module in management bay 2.
Note: Only one management module will be active; the second management
module, if present, provides redundancy.
The management module functions as a service processor and a
keyboard/video/mouse (KVM) multiplexor for the multiple blade servers. The
management module also configures the BladeCenter unit and modules, configuring
information such as switch module IP addresses. The management module
provides the following external connections: keyboard, mouse, and video for use by
a local console, and one RJ-45 connector for a 10/100 Mbps Ethernet remote
management connection.
The service processor in the management module communicates with the service
processor in each blade server for functions such as:
v Blade server power-on requests
v Blade server error and event reporting
v Blade server requests for keyboard, mouse, and video
v Blade server requests for diskette drive, CD-ROM drive, and USB port
The management module also communicates with the I/O modules, power modules,
blower modules, and blade servers to detect presence or absence and any error
conditions, sending alerts when required.
Chapter 2. Installing options 15
I/O modules
For blade server communication with the network, your BladeCenter unit supports
from one to four hot-swap I/O modules. Table 2 identifies the type of I/O module
you can install in each I/O-module bay. Go to the IBM Support Web site at
http://www.ibm.com/pc/support/ to see the list of supported I/O modules.
Your BladeCenter unit supports a minimum of one hot-swap Ethernet switch module
or pass-thru module, in I/O-module bay 1 or 2. This I/O module provides an internal
connection to an integrated Ethernet controller in all the blade servers in the
BladeCenter unit, up to 14 internal connections per I/O module. To provide an
internal connection for the second integrated Ethernet controller in each blade
server, install an Ethernet switch module or pass-thru module in the available
I/O-module bay of the pair (I/O-module bay 1 or bay 2).
Similarly, the BladeCenter unit supports two additional I/O modules in I/O-module
bays 3 and 4. Each of these I/O modules provides an internal connection to one of
the two network-interface controllers on all the I/O expansion options installed on
blade servers in the BladeCenter unit. The I/O module must be compatible with the
network interface on all the I/O expansion options. For example, if you install a
Fibre Channel I/O expansion option on a blade server, the I/O modules you install
in I/O-module bays 3 and 4 must be Fibre Channel switch modules or pass-thru
modules.
Notes:
1. Because of electromagnetic interference (EMI), no more than two four-port 1-Gb
Ethernet switch modules can be installed in the BladeCenter unit. You can mix
four-port 1-Gb Ethernet switch modules with other supported Ethernet switch
modules to achieve the total number of Ethernet switch modules you need in
the BladeCenter unit.
2. You can use a pass-thru module in any I/O-module bay, provided the associated
controller in the blade servers or I/O expansion options is compatible with it.
The following table summarizes the types of modules that can be used in each
I/O-module bay. See “Rear view” on page 33 for the location of the I/O-module bays
on the BladeCenter unit.
Table 2. Hot-swap I/O module types by location
Bays I/O-module function Permissible I/O module
1 and 2 Network connections 1 and 2
(Ethernet) for all blade servers in the
BladeCenter unit
3 and 4 Network connections 3 and 4 (for all
I/O expansion options on blade
servers in the BladeCenter unit)
One of the following combinations:
v Two Ethernet switch modules
v Two pass-thru modules
v One Ethernet switch module and
one pass-thru module
One of the following combinations.
v Two Ethernet switch modules
v Two Fibre Channel switch modules
v Two pass-thru modules
Important:
v The modules used must support the
network interface used on the I/O
expansion options.
v The I/O modules in bays 3 and 4
must be the same type.
