4 BladeCenter E Type 8677: Installation and User’s Guide

The BladeCenter modules

The BladeCenter unit contains the following hot-swap modules:

v Management modules v I/O modules v Blade servers v Power modules v Blower modules

See “Front view” on page 14 and “Rear view” on page 16 for the location of each module.

The BladeCenter unit and the active management module make optional I/O devices (CD/DVD drive, USB port, keyboard, video, and mouse) available to all the blade servers, selected by any one blade server at a time.

Management modules

The BladeCenter unit comes with at least one hot-swap management module in management-module bay 1. An optional second management module in management-module bay 2 provides management redundancy. The management modules are hot-swap BladeCenter modules that you use to configure and manage all installed BladeCenter components.

The type of management modules that are installed in your BladeCenter unit depends on the BladeCenter unit model and devices that are installed. When two modules are installed they must be the same type.

v A BladeCenter unit that has a media tray with a diskette drive can use either

management modules or advanced management modules, depending on which devices are installed in the BladeCenter unit.

v A BladeCenter unit that has a media tray without a diskette drive must use

advanced management modules.

v If 2320-watt power modules are installed in the BladeCenter unit, you must use

advanced management modules.

v See the documentation that comes with your BladeCenter device to determine if

specific management modules are required to support the device.

See the User's Guide or the Command-Line Interface Reference Guide for your management module type for more information.

Chapter 1. Introduction 5

I/O modules

The BladeCenter unit supports from one to four hot-swap I/O modules. Table 1 identifies the type of I/O module you can install in each I/O-module bay. See http://www.ibm.com/support/ for a list of supported I/O modules. See “Rear view” on page 16 for the location of the I/O-module bays on the BladeCenter unit.

Table 1. 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) are used for all blade servers in the BladeCenter unit.

3 and 4 Network connections 3 and 4

are used 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 that are used must support the

network interface that is used on the I/O expansion options.

v The I/O modules in bays 3 and 4 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. You 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. See the management-module User’s Guide for instructions.

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 the switch module or

pass-thru module is connected to.

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.

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 (I/O-module bay 1 or bay 2).

6 BladeCenter E Type 8677: Installation and User’s Guide

Blade servers

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 that are installed in 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 in 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.

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 that you need in the BladeCenter unit.

2. 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 BladeCenter unit provides 14 bays for blade servers or other BladeCenter 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 slides into a bay in the BladeCenter unit and shares power, blowers, media-tray drives, switches, and ports with other blade servers.

Power modules

The BladeCenter unit comes with two to four hot-swap power modules.

The following table summarizes the application for each power module.

Bays Power module function

1 and 2 Provides power to all the BladeCenter modules and to blade bays 1 through 6 3 and 4 Provides power to blade bays 7 through 14

Power modules are not needed in bays 3 and 4 until you begin installing blade servers and options in blade bays 7 through 14.

Note: If you install a blade server in blade bay 6 that spans two bays or that has

an attached expansion unit, power modules are required in all four power bays.

Each pair of power modules is redundant, depending on power-management settings. 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.

Important:

1. The power modules in a pair must match each other in capacity (wattage).

2. For power redundancy, you must connect the power-module pairs (1 and 3, or 2 and 4) to different ac power sources that are controlled by separate circuit breakers. For example, when one ac power source fails, the second ac power source handles the power load for the BladeCenter unit.

Chapter 1. Introduction 7

Blower modules

The BladeCenter unit comes with two hot-swap blower modules for cooling redundancy. The blower speeds vary depending on the ambient air temperature at the front of the BladeCenter unit and the temperature of internal BladeCenter components. If the ambient temperature is 22°C (72°F) or below, the BladeCenter unit blowers will run at 30% of their maximum rotational speed, increasing their speed as required to control internal BladeCenter temperature. If the ambient temperature is above 22°C (72°F), the blowers will run at 80% of their maximum rotational speed, increasing their speed as required to control the internal BladeCenter unit temperature. If a blower fails, the remaining blower continues to cool the BladeCenter unit and blade servers. Replace a failed blower as soon as possible, to restore cooling redundancy. See the Hardware Maintenance Manual and Troubleshooting Guide for instructions.
