The BladeCenter HT components

The BladeCenter HT unit supports the following hot-swap components:

v Blade servers

v Media tray

v Advanced management modules

v I/O modules

v Power modules

v Fan modules

v Multiplexer expansion modules

v Alarm panel module

“Major components of the BladeCenter HT Type 8740 and 8750 unit” on page

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:

– Switch modules

– Bridge modules

– Passthrough modules

The modules in I/O bays 7 through 10 support high-speed I/O modules.

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.

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

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.

– To switch the KVM to a specific blade server, press the

blade server.

– To switch the media tray to a specific blade server, press the

that blade server.

The requesting it.

v On a keyboard that is directly attached to the management module, you can

press keyboard keys in the following sequence to switch KVM control between blade servers:

NumLock NumLock blade_server_number Enter

Where blade_server_number is the two-digit number of the blade bay in which the blade server is installed. When you use some keyboards, such as the 28L3644 (37L0888) keyboard, you must hold down the Shift key while you enter this key sequence.

and

management module assigns the resource to the blade server that is

button on that

button on

Note:

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.

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.
