See
11 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 HT
unit.
The BladeCenter HT unit and the active management module make optional I/O
devices (USB devices, keyboard, video, and mouse) available to all the blade
servers, selected by any one blade server at a time.
Blade servers
The BladeCenter HT unit provides 12 bays for blade servers or other BladeCenter
HT devices. A blade server is a hot-swap, independent server with its own
processors, memory, storage, network controllers, operating system, and
applications. The blade server is installed in a bay in the BladeCenter HT unit and
shares power, fans, switches, and ports with other blade servers.
Media tray
The BladeCenter HT unit comes with one hot-swap media tray in media tray bay 1.
You can add a second media tray in media tray bay 2 to provide redundancy.
The media tray is a hot-swap module that provides two USB connectors for use by
the blade servers, error LEDs, an ambient air temperature sensor and a pressure
sensor for use by the advanced management module, and two CompactFlash bays.
Advanced management module
The BladeCenter HT unit comes with one hot-swap advanced management module
in management-module bay 1. You can add a second advanced management
module in management-module bay 2 to provide redundancy.
When installing an advanced management module into the BladeCenter HT
Note:
unit, an advanced management-module interposer must be installed into the
bay before installing the advanced management module.
The advanced management module is a hot-swap module that you use to configure
and manage BladeCenter HT components. See the User’s Guide that comes with
the advanced management module for more information.
Chapter 1. Introduction 5
I/O modules
Power modules
The BladeCenter HT unit has eight hot-swap I/O-module bays that are compatible
with three types of I/O modules (see “BladeCenter HT components and LEDs” on
page 18 for the location of the I/O module bays). These bays can be used as
follows:
Notes:
1. When installing an I/O module into the BladeCenter HT unit, an I/O-module
interposer must be installed into the bay before installing the I/O module.
2. When installing a high-speed I/O module into the BladeCenter HT unit, a
high-speed I/O-module interposer tray with interposer card must be installed into
the bay before installing the high-speed I/O module.
The modules in I/O bays 1 through 4 can be either of the following types:
v
– Switch modules
– Bridge modules
– Passthrough modules
The modules in I/O bays 7 through 10 support high-speed I/O modules.
v
The BladeCenter HT unit is configured with two or four hot-swap power modules.
Fan modules
Power modules are required in bays 1 and 2, and they supply power to blade bays
1 through 6, media trays 1 and 2, management-module bays 1 and 2, and
I/O-module bays 1 through 4.
Power modules are required in power module bays 3 and 4 if you install blade
servers in blade bays 7 through 12 or if you install I/O modules in any of
I/O-module bays 7 through 10.
Each pair of power modules operates as a redundant pair. If either power module
fails, the remaining power module continues to supply power, but there is no
redundancy; the failed power module must be replaced as soon as possible.
The BladeCenter HT unit comes with four hot-swap fan modules for cooling
redundancy. The fan module speeds vary depending on the ambient air temperature
within the BladeCenter HT unit, which is reported by the media tray. If the ambient
temperature is 25°C (77°F) or below, the BladeCenter HT unit fan modules will run
at their minimum rotational speed, increasing their speed as required to control
internal BladeCenter HT temperature. If the ambient temperature is above 25°C
(77°F), the fan modules will run faster, increasing their speed as required to control
internal BladeCenter HT unit temperature. Each fan module contains two fans
operating as a pair in a series. If one fan fails, the remaining fan will run at full
speed and continue to cool the BladeCenter HT unit. Replace a failed fan module
as soon as possible, to restore cooling redundancy.
Attention: If more than two fan modules are removed or more than two fan
modules experience a double fan failure, the blade servers will shut down within 1
to 3 seconds.
Multiplexer expansion modules
The BladeCenter HT unit comes with two hot-swap multiplexer expansion modules
for redundancy. The multiplexer expansion module controls the USB connectors,
6 BladeCenter HT Type 8740 and 8750: Installation and User’s Guide
video signal, console redirection, and status LEDs on the BladeCenter HT unit.
Replace a multiplexer expansion module as soon as possible, to restore
redundancy.
Alarm panel module
The BladeCenter HT unit comes with an alarm panel module. The alarm panel
provides telecom relays and LED alarm status with additional functionality of a
serial console through the serial port on each blade server in the chassis using an
external breakout cable.

Installing the BladeCenter HT unit in a rack
Install the BladeCenter HT unit in a rack before you install any modules or blade
servers in the BladeCenter HT unit. Reduce the weight of your BladeCenter HT unit
by removing any blade servers, power modules, and fan modules that are
preinstalled. The fan shuttle must also be removed from the rear of the BladeCenter
HT unit. You can further reduce the weight of the BladeCenter HT unit by removing
any preinstalled media trays, management modules, and I/O modules. Lift handles
come with your BladeCenter HT unit. See the rack installation instructions for more
information on installing the lift handles. Instructions for installing a BladeCenter HT
unit in a 4-post rack are in the BladeCenter HT 4-Post Rack Installation Instructions
and instructions for installing a BladeCenter HT unit in a 2-post rack are in the
BladeCenter HT 2-Post Rack Installation Instructions that come with the
BladeCenter HT unit.
Installation guidelines
Before you install any modules or fillers in the BladeCenter HT unit, read the
following information:
v Read the safety information that begins on page vii and the guidelines in
“Handling static-sensitive devices” on page 27. This information will help you
work safely.
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 HT 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 You do not have to disconnect the BladeCenter HT unit from power to install or
replace any of the hot-swap modules in the BladeCenter HT unit. You must shut
down the operating system and turn off a blade server before you remove the
blade server, but you do not have to shut down the BladeCenter HT unit itself.
v Blue on a component indicates touch points where you can grip the component
to open and close a latch, or grab a component to remove it from or install it into
the BladeCenter HT unit.
v For a list of supported optional devices for the BladeCenter HT unit, see
http://www.ibm.com/servers/eserver/serverproven/compat/us/.
System reliability guidelines
To help ensure proper cooling and system reliability, make sure that the following
requirements are met:
v Each of the module bays on the BladeCenter HT unit has either a module or a
module filler installed.
v Each of the blade bays on the front of the BladeCenter HT unit has either a
blade server or a blade filler installed.
v Each of the drive bays in a blade server storage expansion unit has either a
hot-swap drive or a filler installed.
v A removed hot-swap module, blade server, or drive is replaced within 1 minute of
removal.
v Cables for the optional modules are routed according to the illustrations and
instructions in this document.
v A failed fan is replaced as soon as possible, to restore cooling redundancy.
26 BladeCenter HT Type 8740 and 8750: Installation and User’s Guide
Handling static-sensitive devices
Attention: Static electricity can damage the BladeCenter HT unit and other
electronic devices. To avoid damage, keep static-sensitive devices in their
static-protective packages until you are ready to install them.
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. Use
an ESD wrist strap and the ESD connectors on the BladeCenter HT unit. See
“Front view” on page 18 and “Rear view” on page 21 for the locations of the ESD
connectors on your BladeCenter HT unit. The ESD wrist strap safely channels the
electricity from your body to a proper ground (the BladeCenter HT unit). 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 HT unit). Use an ESD wrist strap whenever you are working on the
BladeCenter HT unit and BladeCenter HT components.
To reduce the possibility of electrostatic discharge, observe the following
precautions:
v Use an ESD wrist strap whenever you are working on the BladeCenter HT unit
and BladeCenter HT components.
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 BladeCenter HT unit or rack 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 immediately without setting it
down. If it is necessary to set down the device, put it back into its
static-protective package.
v Take additional care when you handle devices during cold weather. Heating
reduces indoor humidity and increases static electricity.

62 BladeCenter HT Type 8740 and 8750: Installation and User’s Guide
Chapter 4. Configuration and networking guidelines
The BladeCenter HT components are configured and managed through a
management module. You can configure the management module and the
BladeCenter HT unit components through a local or remote connection and
management-module user interfaces or other system management tools. See your
management-module documentation for instructions for configuring the BladeCenter
HT unit.
Configuring the BladeCenter HT unit
General configuration of the BladeCenter HT unit and installed components is
performed through the management module. See the BladeCenter HT Management
Module User’s Guide and the BladeCenter HT Management Module Command-Line
Interface Reference Guide for your management module for information and
instructions. Some devices in the BladeCenter HT unit, such as I/O modules and
blade servers, might also require additional configuration. See the documentation
that comes with each device for information and instructions.
Configuring the management module
All management modules are preconfigured with the same static IP address. Yo u
can use the management module user interface to assign a new static IP address.
To establish connectivity, the management module attempts to use Dynamic Host
Configuration Protocol (DHCP) to acquire its initial IP address for the
management-module Ethernet port. If DHCP is not installed or is enabled and fails,
the management module uses the static IP address. Use the management module
to configure other BladeCenter HT component settings, such as user accounts,
DHCP, or Wake on LAN. See the documentation for your management module for
instructions.
Configuring I/O modules
You must install and configure at least one external (in-band) port on an Ethernet
switch module in I/O-module bay 1 or 2 to communicate with the Ethernet
controllers that are integrated in each blade server. See the documentation for your
management module for information about configuring external ports on I/O
modules. For I/O-device settings, see the documentation that comes with your I/O
device.
Note: If a pass-thru module is installed in I/O-module bay 1 or 2, you must
configure the external network switch to which the pass-thru module is
connected; see the documentation that comes with the external network
switch.
Configuring blade servers
To achieve blade server redundancy, you must configure the Ethernet controllers in
one or more blade servers for failover. When failover occurs on a blade server, the
secondary Ethernet controller takes over network communications, using the I/O
module that is associated with that controller. Install a pair of Ethernet switches in
I/O-module bays 1 and 2, and then configure them and your network infrastructure
so that they can direct traffic to the same destinations. You can also install a
pass-thru module that is connected to an external Ethernet switch in either or both
of these I/O-module bays. See the documentation that comes with your blade
server and operating system for instructions.

BladeCenter HT networking guidelines
Make sure the network infrastructure is configured before you connect the
BladeCenter HT unit to a LAN switch or similar network device.
Each blade server has two independent Ethernet controllers, each with its own
MAC address and a dedicated 1000 Mbps link to one of the switch modules in
I/O-module bays 1 and 2. Switches that support Inter Switch Link (ISL) can be
configured to support switch to switch traffic on up to two internal switch link
interconnections between the peer switches. These ports can be configured as a
trunk group between these peer switches.
When installing a switch module that supports ISL, a switch-module
Note:
interposer that also supports ISL must be installed into the same I/O bay.
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.

Chapter 6. Shared BladeCenter HT resources
The BladeCenter HT unit provides resources that are available to most blade
servers at all times, such as power modules, cooling, system-management, and
network I/O modules; no user intervention is required. Some resources are
selectable for use by a single blade server at a time, such as the media tray or the
keyboard-video-mouse (KVM). You can select the resources for a blade server in
the following ways.
Attention: Do not switch ownership of the media tray to another blade server
while a transaction is taking place on an attached USB device, such as a USB
CD-ROM drive. The data might become corrupted. Make sure that activity lights on
the USB devices are not lit.
v Most blade servers have two selection buttons on the front of the blade server
CD
v You can use the management-module Web interface to enable or disable the
selection buttons on the blade servers and change ownership of the media tray
or the KVM (Blade Tasks → Remote Control).
The monitor that is attached to the management module shows the video output
from the blade server that is the current owner of the KVM. When there is no
actively selected video from any blade server, the video from blade server 12 is
routed to the management module. While the management module is restarting,
there is temporarily no current KVM owner. The video from blade server 12 is
displayed on the monitor briefly until the management module uses its NVRAM
values to reestablish ownership of the KVM and media tray. After that, the video
from the blade server that is the current KVM owner is displayed on the monitor.

The KVM control key sequence does not change the ownership of the
media tray resources.
It can take up to 20 seconds for the operating system in the switched-to blade
server to recognize the media tray or the KVM. If you install Microsoft Windows
2000 on a blade server while it is not the current owner of the media tray or the
KVM, the first time the blade server requests ownership after the operating system
has been installed, it can take up to 1 minute for the operating system to recognize
the devices (this is a one-time-only occurrence).
Note: The operating system in the blade server must provide USB support for the
blade server to recognize and use the media tray. The BladeCenter HT unit
uses USB for internal communication with these devices.

Light path diagnostic LEDs
Light path diagnostic LEDs are a system of LEDs on the BladeCenter HT unit and
the BladeCenter HT components that can be used to diagnose system errors. If the
front or rear system-error LED on the BladeCenter HT unit is lit, one or more error
LEDs on the BladeCenter HT components also might be lit. These LEDs help to
identify the cause of the problem.
Diagnosing problems by using diagnostic LEDs
To identify the component that is causing the error, locate the lit error LED on that
component.
The following example shows how to use the LEDs to diagnose a system error:
1. Note that the BladeCenter HT system-fault LEDs are lit on the media tray LED
panel.
2. Locate the module or blade server that also has a lit error LED (see
“BladeCenter HT components and LEDs” on page 18 for the locations of error
LEDs; see the documentation that comes with your blade server for the
locations of error LEDs on the blade server).
v If the component is a module, replace the module.
v If the component is a blade server on which a system-error LED is lit, follow
the instructions in the documentation that comes with the blade server to
isolate and correct the problem.
Diagnostic LEDs
Use the following table to find solutions to problems that are identified by LEDs on
the front and rear BladeCenter HT system LED panels.
Lit LED Cause Action

not present or not functioning.
Attention: If the power-on LED is off, it does
not mean that no electrical current is present in
the BladeCenter HT unit. The LED might be
burned out. To remove all electrical current
from the BladeCenter HT unit, you must
disconnect all power cords from all power
modules.
