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.
