7. Restart the Management Module. In the Management Module Web interface,
select MM Control Restart MM. Then click the Restart button on the
displayed form. You are prompted to confirm the restart before it occurs.
8. Remove the Management Module from the isolated private Ethernet network
and connect it to the network you will use to manage the BladeCenter.
You can now connect to the Management Module Web and command line
interfaces using the IP address that you assigned to the Management Module
external network interface.
Now consider performing other Management Module setup tasks, such as:
򐂰 Setting the Management Module date and time so that log entries have useful
timestamps
򐂰 Defining user IDs and passwords for the system administrators and operators
who will manage the BladeCenter
Alternatively, you can configure the Management Module to use a Lightweight
Directory Access Protocol (LDAP) directory for this purpose.
򐂰 Configuring the Management Module to send alerts to management systems
via SNMP, or system administrators using e-mail via Simple Mail Transfer
Protocol (SMTP)
򐂰 Enabling the use of Secure Sockets Layer (SSL) to securely access the
Management Module Web interface
򐂰 Enabling the use of Secure Shell (SSH) to securely access the Management
Module command line interface (CLI)
For additional information about how to perform these tasks, refer to the
IBM Eserver BladeCenter Management Module User’s Guide.
5.2 LAN Switch I/O Module configuration
This section explains the basic set up LAN Switch I/O Modules so you can work
with BladeCenter JS20s. Advanced configuration of LAN Switch I/O Modules is
beyond the scope of this book.
The primary setup tasks for LAN Switch I/O Modules are to:
򐂰 Assign IP addresses to the LAN Switch I/O Module management interfaces
򐂰 Enable the LAN Switch I/O Module external Ethernet ports
You can learn about the selection of IP addresses for the LAN Switch I/O Module
management interfaces in Chapter 4, “Planning considerations” on page 53.
74 The IBM Eserver BladeCenter JS20
When a new LAN Switch I/O Module is first installed, the Management Module
assigns a default IP address to the management interface of the LAN Switch I/O
Module. The default IP address is chosen based on the I/O module bay where
the LAN Switch I/O Module is installed. Those I/O modules installed in I/O
module bays 1, 2, 3, and 4 are assigned IP addresses 192.168.70.127,
192.168.70.128, 192.168.70.129, and 192.168.70.130, respectively.
Set the IP address of each LAN Switch I/O Module management interface and
enable the external ports:
1. Connect to the Management Module using the Web browser interface as
explained in “Configuring the Management Module” on page 71.
2. From the Management Module Web interface, select I/O Module Tasks
Management.
3. In the form shown in Figure 5-3, scroll down to the entry for the LAN Switch
I/O Module that you want to configure. Enter the IP address, subnet mask,
and gateway that you want to assign to the LAN Switch I/O Module
management interface. Click the Save button to activate the new IP address.

4. You are prompted to confirm that you want to change the IP address.
5. Select the Advanced Management link for the LAN Switch I/O Module.
6. Scroll down to the Advanced Setup section of the displayed form. This is
illustrated in Figure 5-4. For the External Ports field, select Enabled from the
drop-down list and then click the Save button.
