The IBM eServer BladeCenter JS20 - IBM Redbooks

5.1 Management Module configuration
This section describes the steps to set up the BladeCenter Management Module
so that you can work with BladeCenter JS20s. Advanced configuration of the
Management Module is beyond the scope of this book.
The primary setup task for the Management Module is to assign IP addresses,
which are necessary to communicate with the Management Module Web and
command line interfaces. To learn more about selecting these IP addresses, see
Chapter 4, “Planning considerations” on page 53.
The Management Module has two network interfaces, an external interface
(eth0) and an internal interface (eth1). The external interface is accessible via the
10/100BaseT connector on the Management Module. The internal interface is
connected to the management interfaces of all the installed I/O modules that
support such interfaces. This includes all switch I/O modules.
The default behavior of a new Management Module is to request an IP address
for the external interface via DHCP. If the Management Module does not receive
a valid response from a DHCP server within two minutes of powering on, it uses
a default static IP address of 192.168.70.125 with the default subnet mask of
255.255.255.0.
Note: The default host name is MMxxxxxxxxxxxx, where xxxxxxxxxxxx is the
burned-in medium access control (MAC) address.
The default IP address for the internal interface is statically assigned to be
192.168.70.126 with a subnet mask of 255.255.255.0.
You can reset the IP addresses of a Management Module that was previously
configured back to the factory defaults by using the IP reset button shown in
Figure 5-1 on the Management Module. You can find the procedure for doing this
in the IBM Eserver BladeCenter Management Module User’s Guide.
