Chapter 4. Configuration and networking guidelines The BladeCenter components are configured and managed through a management module. Depending on your management module type, you can configure the management module and the BladeCenter 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 unit. Configuring the BladeCenter unit General configuration of the BladeCenter unit and installed components is performed through the management module. See the BladeCenter Management Module User's Guide and the BladeCenter Management Module Command-Line Interface Reference Guide for your management module for information and instructions. Some devices in the BladeCenter 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 preconfigured with the same static IP address. You can use the management module 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 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 network switch that the pass-thru module is connected to; see the documentation that comes with the 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. © Copyright IBM Corp. 2010 35

Chapter 4. Configuration and networking guidelines
The BladeCenter components are configured and managed through a management
module. Depending on your management module type, you can configure the
management module and the BladeCenter 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 unit.
Configuring the BladeCenter unit
General configuration of the BladeCenter unit and installed components is
performed through the management module. See the
BladeCenter Management
Module User’s Guide
and the
BladeCenter Management Module Command-Line
Interface Reference Guide
for your management module for information and
instructions. Some devices in the BladeCenter 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 preconfigured with the same static IP address. You can
use the management module 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 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 network switch that the pass-thru module is connected to; see
the documentation that comes with the 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.
