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. You
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
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.

configure the external network switch to which the pass-thru module is
connected; see the documentation that comes with the external network
switch.
