v If you plan to use redundant management modules and want both to use the
same IP address, disable DHCP and configure and use the static IP address (the
IP configuration information will be transferred to the redundant management
module automatically when needed). Otherwise, configure the DHCP setting as
you prefer. You need to configure the static IP address only if DHCP is disabled.
– IP address - The IP address for the management module. The IP address
must contain four integers from 0 to 255, separated by periods, with no
spaces or consecutive periods. The default setting is 192.168.70.125.
– Subnet mask - The subnet mask must contain four integers from 0 to 255,
separated by periods, with no spaces. The default setting is 255.255.255.0
– Gateway address - The IP address for your network gateway router. The
gateway address must contain four integers from 0 to 255, separated by
periods, with no spaces.
Configuring the internal Ethernet port
Under MM Control, click Network Interfaces → Internal Network Interface (eth1).
This interface communicates with the network-interface I/O modules, such as the
Ethernet switch module or the Fibre Channel switch module.
v Specify the IP address to use for this interface. The subnet mask must be the
same as the subnet mask in the external network interface (eth0).
v You can configure the locally-administered MAC address for this interface; the
other fields (data rate, duplex mode, maximum transmission unit (MTU), and
burned-in MAC address) are read-only.
Configuring the management port on I/O modules
Under I/O Module Tasks, click Management; then, click the bay number that
corresponds to the I/O module you are configuring.
v In the New Static IP address fields, specify the IP address to use for this
interface. The subnet mask must be the same as the subnet mask in the internal
network interface (eth1).
v Click Advanced Management → Advanced setup. Enable the external ports and
external management.
Saving and restoring the configuration file
After you have configured the management module, you can save the configuration
file to a diskette or other external media. Then, if the configuration in the
management module becomes damaged or the management module is replaced,
you can restore the saved configuration file to the management module. Use the
management-module Web interface to save and restore the configuration file (MM
Control → Configuration File).
Note: If you cannot communicate with a replacement management module through
the Web interface or the IBM Director programs, the IP address might be
different from the IP address of the management module just removed.
Press the IP reset button to set the management module to the factory
default IP addresses; then, access the management module using the
factory IP address (see “Configuring the management module for remote
access” on page 39 for the factory IP addresses) and configure the
management module or load the saved configuration file.
