viii BladeCenter T Type 8720 and 8730: Hardware Maintenance Manual and Troubleshooting Guide
Chapter 1. General information
®
The IBM
high-density, high-performance blade server systems developed for
telecommunications network applications and other applications requiring physical
robustness.
The BladeCenter T unit 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 T unit supports up to
eight blade servers and four I/O modules, making it ideally suited for networking
environments that require a large number of high-performance servers in a small
amount of space. The BladeCenter T unit 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 T system.
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.

22 BladeCenter T Type 8720 and 8730: Hardware Maintenance Manual and Troubleshooting Guide
Chapter 2. Configuring the BladeCenter T unit
The BladeCenter T unit automatically detects the modules and blade servers that
are installed and stores the vital product data (VPD). When the BladeCenter T unit
is started, the management module automatically configures the remote
management port on the management module, accessed through the LAN module
on the rear of the BladeCenter T unit, so that you can configure and manage the
BladeCenter T unit and blade servers. Yo u configure and manage the BladeCenter
T unit remotely, through the management module, using the Web-based user
interface.
Note: There are two ways to configure the switch modules; through the
management-module Web interface, or through an external switch-module
port enabled through the management module, using a Telnet interface or a
Web browser. See the documentation that comes with the switch module for
more information.
For the active management module to communicate with the I/O modules in the
BladeCenter T unit, you must configure the IP addresses for the following internal
and external ports:
v The external Ethernet (remote management) port on the management module,
accessed through the LAN module on the rear of the BladeCenter T unit (see
“Configuring the external Ethernet port” on page 28 for instructions). The initial
management module autoconfiguration enables the network management station
to connect to the management module to configure the port completely and to
configure the rest of the BladeCenter T unit.
v The internal Ethernet port on the management module for communication with
the I/O modules (see “Configuring the internal Ethernet port” on page 29 for
instructions).
v The management port on each switch module provides for communication with
the management module. You configure this port by configuring the IP address
for the switch module (see “Configuring management ports on I/O modules” on
page 29 for instructions).
Note: Some types of I/O modules, such as the pass-thru module, have no
management port.
the documentation that comes with the I/O module to determine what else you
See
must configure in the I/O module.
To communicate with the blade servers for functions such as deploying an operating
system or application program over the network, you must also configure at least
one external (in-band) port on an Ethernet switch module in I/O-module bay 1 or 2.
See “What to configure” on page 29 for information about configuring external ports
on Ethernet switch modules.
The management module supports the following Web browsers for remote access.
The Web browser that you use must be Java™-enabled, must support JavaScript

Management and configuration program
This section provides the instructions for setting up and using the management and
configuration program in the management module.
Setting up the management and configuration program
Complete the following steps to set up the management and configuration program:
1. Connect a PC to the BladeCenter T management network.
2. At initial power-on, the management module configures the Ethernet port
connection in one of the following ways:
v If you have an accessible, active, and configured dynamic host configuration
protocol (DHCP) server on the network, the host name, IP address, gateway
address, subnet mask, and DNS server IP address are set automatically.
v If the DHCP server does not respond within 2 minutes after the port is
connected, the management module uses a default IP address of
192.168.70.125 and subnet mask of 255.255.255.0.
Either of these actions enables the Ethernet to assign a connection.
If you cannot communicate with a replacement management module through
the Web interface. Press the IP reset button on the front of the management
module to set the management module to the factory default IP addresses;
then, access the management module using the factory IP address (see
“Setting up the management and configuration program” for the factory IP
addresses) and configure the management module.
Note: If the IP configuration is assigned by the DHCP server, the network
administrator can query the MAC address of the management-module
network interface on the DHCP server to determine what IP address and
host name are assigned.
26 BladeCenter T Type 8720 and 8730: Hardware Maintenance Manual and Troubleshooting Guide

Chapter 2. Configuring the BladeCenter T unit 27
Setting management and configuration program options
From the management and configuration program main menu, you can select
settings that you want to view or change.
The navigation pane (on the left side of the management module window) contains
navigational links that you use to manage the BladeCenter T unit and check the
status of the components (modules and blade servers). The following information
describes the choices that you have to configure the external Ethernet port on the
management module, the internal Ethernet port on the management module, and
the external management port on each I/O module. See the BladeCenter T
Management Module User’s Guide on the BladeCenter T Documentation CD that
comes with the BladeCenter T unit for a description of all the navigational links.
Configuring the external Ethernet port
Under MM Control, click Network Interfaces ” External Network Interface (eth0).
This is the interface for the remote management and console port.
v Set Interface to Enabled to use the Ethernet connection.
v If you plan to use redundant management modules and want both to use the
same IP address, disable DHCP and configure and use a static IP address (the
IP configuration information will be transferred to the redundant management
28 BladeCenter T Type 8720 and 8730: Hardware Maintenance Manual and Troubleshooting Guide
module automatically when needed). Otherwise, configure the DHCP setting as
you prefer. You must configure the static IP address only if DHCP is disabled.
– IP address - The IP address for the management module. The IP address
must contain four integers from 0 through 255, separated by periods, with no
spaces or consecutive periods. The default setting is 192.168.70.125.
– Subnet mask - The subnet mask must contain four integers from 0 to 255,
separated by periods, with no spaces. The default setting is 255.255.255.0
– Gateway address - The IP address for your network gateway router. The
gateway address must contain four integers from 0 through 255, separated by
periods, with no spaces.
Configuring the internal Ethernet port
Under MM Control, click Network Interfaces ” Internal Network Interface (eth1).
This interface communicates with the network-interface I/O modules, such as the
Ethernet switch module or the Fibre Channel switch module.
v Specify the IP address to use for this interface. The IP addresses for the internal
Ethernet port (eth1) and external Ethernet port (eth0) must be on the same
subnet.
v (Optional) Configure the locally-administered MAC address for this interface; the
other fields (data rate, duplex mode, maximum transmission unit (MTU), and
burned-in MAC address) are read-only.
Configuring management ports on I/O modules
Under I/O Module Tasks, click Management; then, click the bay number that
corresponds to the I/O module that you are configuring.
v In the New Static IP address fields, specify the IP address to use for this
interface. The new static IP address must be on the same subnet as the internal
network interface (eth1).
v Click Advanced Management ” Advanced setup. Enable the external ports.
v Click Advanced Management ” Advanced setup. (Optional) Enable external
management.
Saving and restoring the configuration file
After you have configured the management module, you can save the configuration
file to a drive attached to the system running the management-module Web
interface. Then, if the configuration in the management module becomes damaged
or if the management module is replaced, you can restore the saved configuration
file to the management module. Use the management-module Web interface to
save and restore the configuration file (MM Control ” Configuration File).
Configuring an I/O module
To connect any of the blade servers to the network, you must have an Ethernet
switch module installed in I/O-module bay 1 or 2, or a pass-thru module in
I/O-module bay 1 or 2 connected to an external Ethernet switch. If you have an I/O
expansion option installed on one or more blade servers, you must have compatible
I/O modules (switch modules or other compatible modules) in I/O module bays 3 or
4. See “Removing and installing I/O modules” on page 60 for information about the
location and purpose of each I/O module.
What to configure
You must configure switch-module IP addresses and subnet masks through the
management-module Web interface to communicate with the management module
Chapter 2. Configuring the BladeCenter T unit 29
and remote management station. This is in addition to the IP addresses that are
configured on the management module. You might also have to use the user
interface on the switch module to configure the switch external ports to operate in
the correct link aggregation (trunking) mode, or to configure any VLANs or other
special conditions.
To allow blade servers to communicate with the network, make sure that the
External ports configuration item in the management module is set to Enabled. In
the management-module Web interface, under I/O Module Tasks, click
Management ” Bay n ” Advanced Management ” Advanced Setup and enable
the item (where n is the number of the I/O bay).
To access the user interface using external ports on the switch module, make sure
that the External management over all ports configuration item is set to enabled.
See your network administrator before enabling this feature.
Because all blade servers in the BladeCenter T unit share access to the external
LAN through the switch ports, you can configure the ports on a switch module to
operate together as an aggregate link, or trunk. An aggregate link provides more
bandwidth than a single link to the attached LAN.
Notes:
1. The attaching LAN switch must have a compatible multiport trunk configuration.
2. Configure link aggregation before you attach cables between the external ports
and your LAN equipment.
Configure
the switch through the user interface on the switch module, which you
can access through the Web interface to the management module (click I/O
Module Tasks ” Management ” Advanced Management ” Start Telnet/Web
Session in the navigation pane).
Important: For a remote management station, such as a management server, to
communicate with the switch modules in the BladeCenter T unit, the management
port of the switch module must be on the same subnet as the management module.
Supporting Ethernet failover
To have the BladeCenter T unit support Ethernet failover on the blade servers, set
up the BladeCenter T unit and blade servers as follows:
1. Configure the Ethernet controllers in one or more blade servers for failover (see
the blade server documentation and the operating-system documentation for
information). When failover occurs on a blade server, the secondary Ethernet
controller takes over network communication, using the I/O module associated
with that controller.
2. Install a switch module or a pass-thru module that is connected to external
Ethernet switches in both I/O-module bays 1 and 2.
3. Configure the Ethernet switch modules and your network infrastructure so that
they can direct traffic to the same destinations.
Configuring the Ethernet controllers in the blade servers
Note: The BladeCenter T unit does not include an Ethernet switch module; this is
an optional feature that must be purchased separately. An Ethernet switch
module or a pass-thru module is connected to an external Ethernet switch
30 BladeCenter T Type 8720 and 8730: Hardware Maintenance Manual and Troubleshooting Guide
must be installed in the BladeCenter T unit in I/O-module bay 1 or 2, or both,
before the integrated Ethernet controllers on each blade server system board
can be used.
The Ethernet controllers are integrated on each blade server system board. The
Ethernet controllers provide 1-Gbps full-duplex capability only, which enables
simultaneous transmission and reception of data to the external ports on the
Ethernet switches. You do not need to set any jumpers or configure the controller
for the blade server operating system. However, you must install a device driver on
the blade server to enable the blade server operating system to address the
Ethernet controller. For blade server device drivers and information about
configuring the Ethernet controllers, see the Ethernet software CD that comes with
your blade server.
BladeCenter T networking guidelines
Your networking administrator should assist in the configuration of the network
infrastructure before you connect the BladeCenter T unit to a LAN switch or similar
network device. This section provides additional guidelines that might be useful in
setting up your system.
A BladeCenter T unit with two Ethernet switch modules and one management
module has the internal configuration that is shown in the following illustration:

Note: 2nd switch module is optional
Each blade server has two independent Ethernet controllers, each with its own
MAC address and a dedicated 1 Gbps link to one of the switch modules in I/O
module bays 1 and 2 (controller 1 to switch A and controller 2 to switch B in the
illustration). In this configuration (the default), the blade servers share access to
four external ports on each switch. There is no internal data path between the two
switches within the BladeCenter T unit; an external network device is required for
data packets to flow from one internal switch to the other.
The management module has a separate internal 100 Mbps link to each switch.
These links are for internal management and control only. No data packets are
allowed to flow from application programs on the blade servers to the management
module over this path. A separate, nonswitched path (not shown) is used for
communication between the management module and a service processor on each
blade server.

In this configuration, each BladeCenter T unit contains two Ethernet switch modules
and one management module. The external ports on the switch modules are
configured for multiport link aggregation groups, or trunks, as are the corresponding
ports on the attached external LAN switches. Additionally, every port in the switch
module in I/O-module bay 1 (switch A in this illustration) in the BladeCenter T units
is connected to the same external LAN switch, and every port in the switch module
in I/O-module bay 2 (switch B in this illustration) in the BladeCenter T units is
connected to another external LAN switch.
Observe the following guidelines when creating this topology:
1. The external ports on the BladeCenter T switch modules are designed for
point-to-point, full-duplex operation to a compatible LAN switch or router.
Configure a corresponding multiport link aggregation group, or trunk, in both the
switch module and the attached LAN switch before installing the cables. The
connection options are as follows, in order of preference:
v Multiport link aggregation group or trunk, 1 Gbps (1000 Mbps) per port
v Single-uplink port, 1 Gbps
v Multiport link aggregation group or trunk, 100 Mbps per port
Connect the management-module 10/100 Mbps Ethernet port to a separate
2.
layer 2 network for security. If a separate network is not available, you can
attach the Ethernet ports of the management module and switch modules to the
same layer 2 network.
32 BladeCenter T Type 8720 and 8730: Hardware Maintenance Manual and Troubleshooting Guide
3. Avoid network configurations that could lead to data loops, if possible. Loops
will be created if you connect multiple ports from the same switch module to the
same layer 2 network device without first enabling link aggregation. If you
implement configurations that include data loops, you must enable Spanning
Tree Protocol on the switch-module external ports.
Using Remote Deployment Manager Version 4.11 Update 3 or later
You can use the Remote Deployment Manager (RDM) Version 4.11 Update 3 (or
later) program to install a supported Microsoft Windows
BIOS update onto a blade server. Follow the instructions in the documentation that
comes with the RDM program to install a supported Microsoft Windows operating
system, supported Red Hat Advanced server 2.1, or BIOS code update.

configuration. See the IBM Eserver BladeCenter T Planning and Installation
Guide for more examples of network configurations. You can obtain the

To communicate with the BladeCenter T unit, the IBM Director software needs a
managed object (in the Group Contents pane of the IBM Director Management
Console main window) that represents the BladeCenter T unit. If the BladeCenter T
management-module IP address is known, the network administrator can create an
IBM Director managed object for the unit. If the IP address is not known, the IBM
Chapter 2. Configuring the BladeCenter T unit 33
It is
Director software can automatically discover the BladeCenter T unit (out-of-band,
using the Ethernet port on the management module) and create a managed object
for the unit.
For the IBM Director software to discover the BladeCenter T unit, your network
must initially provide connectivity from the IBM Director server to the BladeCenter T
management-module Ethernet port. To establish connectivity, the management
module attempts to use DHCP to acquire its initial IP address for the Ethernet port.
If the DHCP request fails, the management module uses a static IP address.
Therefore, the DHCP server (if used) must be on the management LAN for the
BladeCenter T unit.
Notes:
1. All management modules are preconfigured with the same static IP address.
You can use the management-module Web interface to assign a new static IP
address for each BladeCenter T unit. If DHCP is not used and you do not
assign a new static IP address for each BladeCenter T unit before attempting to
communicate with the IBM Director software, only one BladeCenter T unit at a
time can be added onto the network for discovery. Adding multiple units to the
network without a unique IP address assignment for each BladeCenter T unit
results in IP address conflicts.
2. For switch communication with the IBM Director server through the
management-module external Ethernet port, the switch-module internal network
interface and the management-module internal and external interfaces must be
on the same subnet.

Chapter 3. Diagnostics
This section provides basic troubleshooting information to help you resolve some
common problems that might occur with your BladeCenter T unit.
If you cannot locate and correct the problem using the information in this section,
see Appendix A, “Getting help and technical assistance,” on page 111 for more
information.
Diagnostic tools overview
The following tools are available to help you identify and solve hardware-related
problems:
v Troubleshooting charts
These charts list problem symptoms and steps to correct the problems. See the
Chapter 6, “Symptom-to-FRU index,” on page 89 for more information.
v Diagnostic programs and error messages
The built-in self-test (BIST) program checks the BladeCenter T unit during startup
and generates error messages if problems are found.
The system diagnostic program, Real Time Diagnostics Version 1.3, tests the
major components of your BladeCenter T unit. The Real Time Diagnostics
software is available from the IBM Support Web site at http://www.ibm.com/pc/
support. It is run from the IBM Director Management Console window (under the
BladeCenter T task in the Task panel).
To obtain the Real Time Diagnostics program, go to the following Web site:
http://www.ibm.com/pc/support, and complete the following steps:
1. Select Servers from the list at the left of the window.
2. Select Downloadable files from the list at the left of the window.
3. In the Downloadable files by category list, select Diagnostic.

v Light Path Diagnostics feature
Use the Light Path Diagnostics feature to identify system errors quickly. On the
BladeCenter T unit, the Light Path Diagnostics feature consists of the LEDs on
the front and rear of the BladeCenter T unit and on the front of the modules and
blade servers.
Identifying problems using the Light Path Diagnostics feature
If the system-error LED on the system LED panel on the front or rear of the
BladeCenter T unit is lit, one or more error LEDs on the BladeCenter T components
also might be on. These LEDs help identify the cause of the problem.
This section provides the information to identify problems that might arise during
installation using the Light Path Diagnostics feature.
To locate the actual component that caused the error, you must locate the lit error
LED on that component.
© Copyright IBM Corp. 2004 35
For example:
A system error has occurred, and you have noted that the BladeCenter T
system-error LED is lit on the system LED panel. You then locate the module or
blade server that also has an error LED lit (see “BladeCenter T unit power, controls,
and indicators” on page 19 for the location of error LEDs; see the documentation
that comes with your blade server for the location of error LEDs on the blade). If the
component is a module, replace the module. If the component is a blade server
with its system-error LED lit, follow the instructions in the documentation that comes
with the blade server to isolate and correct the problem.

v System reliability considerations.
v Handling static-sensitive devices and the use of the electro-static discharge
(ESD) connector.
© Copyright IBM Corp. 2004 37
Before you begin to install options in the BladeCenter T unit, read the following
information:
v Read the safety information beginning on page 113 and the guidelines in
“Handling static-sensitive devices” on page 40. This information will help you
work safely with your BladeCenter T unit and options.
v Blue on a component indicates touch points, where you can grip the component
to remove it from or install it in the server, open or close a latch, and so on.
v Orange on a component or an orange label on or near a component indicates
that the component can be hot-swapped, which means that you can remove or
install the component while the BladeCenter T unit is running. (Orange can also
indicate touch points on hot-swap components.) See the instructions for removing
or installing a specific hot-swap component for any additional procedures that
you might have to perform before you remove or install the component.
v Yo u do not need to disconnect the BladeCenter T unit from power to install or
replace any of the hot-swap modules in the BladeCenter T unit. Yo u need to shut
down the operating system and turn off a hot-swap blade server on the front of
the BladeCenter T unit before removing the blade server, but you do not need to
shut down the BladeCenter T unit itself.
v For a list of supported options for your server, go to http://www.ibm.com/pc/
compat/.
Preparing for system power
There a number of basic differences in preparing for system power between the
Type 8720 (dc power) and Type 8730 (ac power) units.
Type 8720 (dc power)
The BladeCenter T unit does not have a power switch. The BladeCenter Type 8720
(dc power) unit has two dc-power terminal connectors each powering two power
modules. The left connection (looking from the rear) supplies power to
power-module bays 2 and 4, while the connection on the right supplies power to
power-module bays 1 and 3.
Each dc terminal has four #M6 (1/4 in.) studs, one for -48 V dc, one for RETURN,
and two for connecting the safety ground wire. The following guidelines are
provided for connecting to the -48 V dc power source:
v DC wire rating of 4AWG (7x7x34/36 TC), 105C, 300V UL 10198, CSA approved
and VW1 rated.
v Ring terminal designed for M6 stud, 4AWG wire, wire size (circular Mil area) of
33100-52600, and a wire insulation diameter of 12.8mm to 13.1mm.
Note: The actual wire gauge and ring terminal will be determined by the current
draw and the length of the wire run or as specified by the customer
premises guidelines.
v A two-lug ring terminal is required by NEBS for connecting the single safety
ground wire.
Attention: Remove the power modules before installing the power connections.
Once the power connections are in place, the power modules can be re-installed in
the BladeCenter T unit.
After you connect power to the BladeCenter T unit, all the power-module bays
receive power. The blade servers in the BladeCenter T unit are connected to dc
power but are not turned on. Press the power-control button on the front of each
blade server to obtain full power for the blade server and start its operating system
38 BladeCenter T Type 8720 and 8730: Hardware Maintenance Manual and Troubleshooting Guide
(see the documentation that comes with your blade server for information about
turning on the blade server). Make sure that you shut down the blade-server
operating system before turning off a blade server, to avoid damaging the hard disk
drives.
Notes:
1. Within two minutes after power has been connected to the BladeCenter T unit,
the management module applies power to the I/O modules.
2. If a power failure occurs, the BladeCenter T unit restarts automatically when
power is restored.
3. The blade-server power button turns on or turns off the blade server if local
power control has not been disabled through the management module.
4. The blade-server power button turns on the blade server only if the green power
light on the blade server is flashing slowly. If the light flashes rapidly, the blade
server has not yet synchronized with the management module and pressing the
power button will have no effect.
Type 8730 (ac power)
The BladeCenter T unit can support two or four power modules.
The BladeCenter T unit does not have a power switch. To start the BladeCenter T

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.
Use an ESD wrist strap and the ESD connectors on the BladeCenter T unit.
Electrostatic discharge (ESD) is the release of stored static electricity that can
damage electric circuits. Static electricity is often stored in your body and
discharged when you come in contact with an object with a different potential. The
ESD wrist strap safely channels the electricity from your body to a proper ground
(the BladeCenter T unit).
Use an ESD wrist strap whenever you are working on the BladeCenter T unit,
especially when you are handling modules, options, and blade servers. To work
properly, the wrist strap must have a good contact at both ends (touching your skin
at one end and connected to the ESD connector on the front or back of the
BladeCenter T unit.)

precautions:
40 BladeCenter T Type 8720 and 8730: Hardware Maintenance Manual and Troubleshooting Guide
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 the 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.

Removing and installing the bezel assembly
The BladeCenter T unit comes with a bezel assembly containing a removable and
replaceable air filter. There are software features in the management-module that
detect a clogged filter and generate system alerts based on the severity of the
airflow reduction. The typical service interval for the filter is approximately three to
six months depending on your environment. Be sure to replace the air filter when
indicated.
Important: If the BladeCenter T unit contains any blade servers with standard
(high-profile) release levers, the bezel assembly will not fit on the chassis. The
bezel assembly and air filter can be used only if all blade servers in the chassis
have low-profile release levers.

Removing and installing power modules
The BladeCenter T unit is separated into two power domains. To support devices in
power domain B, a power-supply module option (consisting of two power modules)
must be installed.
The following table summarizes the modules that are powered by each power
domain.
Power domain Power-module bays Modules powered by the power domain
A 1 and 2 I/O-module bays 1 and 2
Management-module bays 1 and 2
Media tray
Blade bays 1 through 4
B 3 and 4 Blade bays 5 through 8
I/O-module bays 3 and 4
All four blowers are required for redundant system operation. Power for all four
blowers is shared by all installed power modules. One failed blower creates a
nonredundant configuration.
If a power module fails or an input power failure occurs, BladeCenter T units that
are configured for redundant power operation will operate in a nonredundant mode.
You must replace the failing power module or restore input power as soon as
possible to regain redundant power operation.
Important:
1. The power modules must be installed in pairs in a domain and must match each
other in capacity (wattage, amperage, and so on).
2. To provide true redundant power, BladeCenter T power modules 1 and 3 must
be connected to a different input power source than power modules 2 and 4.

The BladeCenter T 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 T unit, up to eight 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). The management modules
are connected to the switch module through the backplane using a transformerless
100 Mbps connection and an I2C interface.
The BladeCenter T 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 each of the I/O expansion options that are installed
on blade servers in the BladeCenter T unit. The I/O module must be compatible
with the network interface on each of the I/O expansion options. For example, if you
install a Fibre Channel I/O expansion card on a blade server, the I/O modules that
you install in I/O-module bays 3 and 4 must be Fibre Channel switch modules or
pass-thru modules.
Important: The switch modules in I/O module bays 3 and 4 and all blade server
interface options in the BladeCenter T unit, must use the same interface type. For
example, if you install an Ethernet interface option on a blade server, the switch
modules that you install in I/O module bays 3 and 4 must be Ethernet. All other
interface options in the BladeCenter T unit must also be Ethernet interface options.
Note: You can use a pass-thru module in any I/O-module bay, provided that 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 15 for the location of the I/O-module bays
on the BladeCenter T unit.

must be the same type.
Notes:
1. The enumeration of the Ethernet controllers in a blade server is
operating-system dependent. You can verify the Ethernet controller designations
that a blade server uses through your operating-system settings.
2. The routing of an Ethernet controller to a particular I/O-module bay depends on
the type of blade server. Yo u can verify which Ethernet controller is routed to
which I/O-module bay by using the following test:
a. Install only one Ethernet switch module or pass-thru module, in I/O-module
bay 1.
b. Make sure that the ports on the switch module or pass-thru module are
enabled (I/O Module Tasks ” Management ” Advanced Management in
the management module Web-based user interface).
c. Enable only one of the Ethernet controllers on the blade server. Note the
designation that the blade server operating system has for the controller.
d. Ping an external computer on the network that is connected to the switch
module or pass-thru module.
If you can ping the external computer, the Ethernet controller that you enabled
is associated with the I/O module in I/O-module bay 1. The other Ethernet
controller in the blade server is associated with the I/O module in I/O-module
bay 2.
3. If you have installed an I/O expansion option on a blade server, communications
from the option are routed to I/O-module bays 3 and 4. You can verify which
controller on the option is routed to which I/O-module bay by performing the test
in note 2, using a controller on the I/O expansion option and a compatible
switch module or pass-thru module in I/O-module bay 3 or 4.

62 BladeCenter T Type 8720 and 8730: Hardware Maintenance Manual and Troubleshooting Guide
Blade servers
The BladeCenter T unit supports up to eight high-performance blade servers. Each
blade server is an enclosure that contains microprocessors, memory, a control chip
set, an I/O bus, Ethernet controllers, hard disk drives or flash drives, and
user-interface controls, and connectors for expansion options. The blade server
receives its power, network connection, and I/O devices (CD-ROM, keyboard,
mouse, and video ports, USB port, remote monitoring port) from the BladeCenter T
unit, reducing the number of cables that are required.
Blade server expansion options
Some blade servers contain connectors for options that add capabilities to the blade
server. You can add these options before installing the blade server in the
BladeCenter T unit.
Go to http://www.ibm.com/pc/compat/ for a list of available options for your IBM
blade server.
I/O expansion option
Some blade servers have connectors for adding an I/O expansion option, such as
an IBM BladeCenter Fibre Channel Expansion Card. The BladeCenter T unit routes
network communication signals from the I/O expansion option to I/O modules 3 and
4 on the BladeCenter T unit. The I/O expansion option is attached directly to the
blade server and does not occupy an additional blade bay.
Note: If an I/O expansion option is installed on any blade server, I/O modules that
are compatible with that network interface must be installed in I/O-module
bays 3 and 4 on the BladeCenter T unit. See “Removing and installing I/O
modules” on page 60 for more information.
Expansion unit option
You can install an optional BladeCenter SCSI Storage Expansion Unit or Peripheral
Card Interface (PCI) I/O Expansion Unit on your blade server.
Storage Expansion Unit option: Some blade servers have a connector for
adding an expansion unit, such as an IBM BladeCenter SCSI Storage Expansion
Unit. The storage expansion unit supports up to two hot-swap SCSI hard-disk
drives. The expansion option is attached directly to the blade server and occupies
an additional blade server bay.
PCI I/O-expansion Unit option: Some blade servers have a connector for adding
an expansion unit, such as an IBM BladeCenter PCI I/O Expansion Unit. The PCI
I/O-expansion unit supports up to two PCI-X adapters. The expansion unit is
attached directly to the blade server and occupies an additional blade server bay.
Chapter 4. Setting up the BladeCenter T hardware 63
Removing and installing a blade server or filler module
Use the instructions in this section to remove or install a blade server at the front of
the BladeCenter T unit.
Important: Reinstalling a blade server into a different bay than the one from which
it was removed could have unintended consequences. Some configuration
information and update options are established according to bay number. Yo u might
need to reconfigure the blade server.
Attention: To maintain proper system cooling, do not operate the BladeCenter T
unit for more than 20 minutes without either a blade server or a filler blade installed
in each blade bay. If you fail to replace a blade server or filler blade within 20
minutes, system performance might be affected.

Chapter 6. Symptom-to-FRU index
This index supports the Eserver BladeCenter T Type 8720 and 8730 systems.
Notes:
1. Check the configuration before you replace a FRU. Configuration problems can
cause false errors and symptoms.
2. For IBM devices not supported by this index, refer to the manual for that device.
3. A removed hot-swap module or drive must be replaced within one minute of
removal.
4. A removed hot-swap blade must be replaced within 20 minutes of removal.
The symptom-to-FRU index lists symptoms, errors, and the possible causes. The
most likely cause is listed first. Use this symptom-to-FRU index to help you decide
which FRUs to have available when servicing the system.
The left-hand column of the tables in this index lists error codes or messages, and
the right-hand column lists one or more suggested actions or FRUs to replace.
Note: In tables with more than two columns, multiple columns are required to
describe the error symptoms.
Take the action or replace the FRU suggested first in the list of the right-hand
column, then try the server again to see if the problem has been corrected before
taking further action.
Error symptoms
Note: Try reseating a suspected component or reconnecting a cable before
replacing the component.
You can use the following information to find solutions to problems that have
definite symptoms.
Attention: If diagnostic error messages appear that are not listed in the following
tables, make sure that your BladeCenter T unit has the latest level of firmware code
installed.
If you have just added a new option and your system is not working, complete the
following procedure before using the troubleshooting charts:
1. Remove the option that you just added.
2. Run the diagnostic tests to determine if your system is running correctly.
3. Reinstall the new device.

Blade server problem
Blade servers turn off for no
apparent reason.
All blade bays must have a blade server, expansion unit, or filler blade in them. Blade
bays that do not have these items installed or have them installed improperly disturb
airflow in the BladeCenter T unit with an adverse effect on BladeCenter T unit
cooling. If the BladeCenter T unit begins to overheat, blade server processors will
begin to slow down and will eventually turn off the system.
Blade server does not turn

replacing a failed microprocessor in a two-way Blade server.

The green status dot for a component is not automatically a link to environmental

those components contains a link to environmental information.
Switching KVM control
between blade servers gives
USB device error.
If a blade server is under heavy load, it can take several minutes before it
enumerates the USB devices connected to it. If control of the KVM and media tray is
switched away from the blade server before this enumeration is complete, a USB
device installation error might be displayed. Do not switch KVM control between
blade servers until the mouse and keyboard are both working on the blade server
that has control of the KVM and media tray.
“Unsafe Removal of Device”
error message appears on

Microsoft Windows 2000.
Before switching ownership of the media tray to another blade server, safely stop the
media tray devices on the blade server that currently owns the media tray, as follows:
1. Double-click the Unplug or Eject Hardware icon in the Windows taskbar at the
bottom right of the screen.
2. Select USB Mass Storage Device, and click Stop.
